GENERAL DESCRIPTION
The AD8515 is a rail-to-rail amplifier that can operate from a single-supply voltage as low as 1.8 V. The AD8515 single amplifier, available in SOT-23-5L and SC70-5L packages, is small enough to be placed next to sensors, reducing external noise pickup. The AD8515 is a rail-to-rail input and output amplifier with a gain bandwidth of 5 MHz and typical offset voltage of 1 mV from a 1.8 V supply. The low supply current makes these parts ideal for battery-powered applications. The 2.7 V/ms slew rate makes the AD8515 a good match for driving ASIC inputs, such as voice codecs. The AD8515 is specified over the extended industrial temperature range (-40C to +125C).

CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the AD8515 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.

FUNCTIONAL DESCRIPTION
0 0 0 VS = 2.5V CL = 50pF GAIN = +1
VOLTAGE (100mV/DIV)
The AD8515, offered in space-saving SOT-23 and SC70 packages, is a rail-to-rail input and output operational amplifier that can operate at supply voltages as low as 1.8 V. This product is fabricated using 0.6 micron CMOS to achieve one of the best power consumption to speed ratios (i.e., bandwidth) in the industry. With a small amount of supply current (less than 400 mA), a wide unity gain bandwidth of 4.5 MHz is available for signal processing. The input stage consists of two parallel, complementary, differential pairs of PMOS and NMOS. The AD8515 exhibits no phase reversal as the input signal exceeds the supply by more than 0.6 V. Currents into the input pin must be limited to 5 mA or less by the use of external series resistance(s). The AD8515 has a very robust ESD design and can stand ESD voltages of up to 4,000 V.

VOLTAGE (100mV/DIV)
One of the strongest features of the AD8515 is the bandwidth stability over the specified temperature range while consuming small amounts of current. This effect is shown in TPC 1 through TPC 3. This product solves the speed/power requirements for many applications. The wide bandwidth is also stable even when operated with low supply voltages. TPC 4 shows the relationship between the supply voltage versus the bandwidth for the AD8515. The AD8515 is ideal for battery-powered instrumentation and handheld devices since it can operate at the end of discharge voltage of most popular batteries. Table I lists the nominal and end of discharge voltages of several typical batteries.

Most amplifiers have difficulty driving large capacitive loads. Additionally, higher capacitance at the output can increase the amount of overshoot and ringing in the amplifier's step response and could even affect the stability of the device. This is due to the degradation of phase margin caused by additional phase lag from the capacitive load. The value of capacitive load that an amplifier can drive before oscillation varies with gain, supply voltage, input signal, temperature, and other parameters. Unity gain is the most challenging configuration for driving capacitive loads. The AD8515 is capable of driving large capacitive loads without any external compensation. The graphs in Figures 1a and 1b show the amplifier's capacitive load driving capability when configured in unity gain of +1. The AD8515 is even capable of driving higher capacitive loads in inverting gain of -1, as shown in Figure 2.

AD8515
Full Power Bandwidth
The slew rate of an amplifier determines the maximum frequency at which it can respond to a large input signal. This frequency (known as full power bandwidth, FPBW) can be calculated from the equation
FPBW = SR 2p VPEAK
for a given distortion. The FPBW of AD8515 is shown in Figure 3 to be close to 200 kHz.

choice of an op amp with a high unity gain crossover frequency, such as the AD8515. The 4.5 MHz bandwidth of the AD8515 is sufficient to accurately produce the 100 kHz center frequency, as the response in Figure 6 shows. When the op amp's bandwidth is close to the filter's center frequency, the amplifier's internal phase shift causes excess phase shift at 100 kHz, which alters the filter's response. In fact, if the chosen op amp has a bandwidth close to 100 kHz, the phase shift of the op amps will cause the loop to oscillate. A common-mode bias level is easily created by connecting the noninverting input to a resistor divider consisting of two resistors connected between VCC and ground. This bias point is also decoupled to ground with a 1 mF capacitor.

A MICROPOWER REFERENCE VOLTAGE GENERATOR
Many single-supply circuits are configured with the circuit biased to one-half of the supply voltage. In these cases, a false ground reference can be created by using a voltage divider buffered by an amplifier. Figure 4 shows the schematic for such a circuit. The two 1 MW resistors generate the reference voltages while drawing only 0.9 mA of current from a 1.8 V supply. A capacitor connected from the inverting terminal to the output of the op amp provides compensation to allow for a bypass capacitor to be connected at the reference output. This bypass capacitor helps establish an ac ground for the reference output.

The circuit in Figure 5 is commonly used in portable applications where low power consumption and wide bandwidth are required. This figure shows a circuit for a single-supply band-pass filter with a center frequency of 100 kHz. It is essential that the op amp has a loop gain at 100 kHz in order to maintain an accurate center frequency. This loop gain requirement necessitates the -12-

Wien Bridge Oscillator
VOLTAGE (2V/DIV)
The circuit in Figure 7 can be used to generate a sine wave, one of the most fundamental waveforms. Known as a Wien Bridge oscillator, it has the advantage of requiring only one low power amplifier. This is an important consideration, especially for batteryoperated applications where power consumption is a critical issue. To keep the equations simple, the resistor and capacitor values used are kept equal. For the oscillation to happen, two conditions have to be met. First, there should be a zero phase shift from the input to the output, which will happen at the oscillation frequency of FOSC 1 = 2pR10 C10
High frequency oscillators can be built with the AD8515 due to its wide bandwidth. Using the values shown, an oscillation frequency of 130 kHz is created and is shown in Figure 8. If R11 is too low, the oscillation might converge; if too large, the oscillation will diverge until the output clips (VS = 2.5 V, FOSC = 130 kHz).
0 0 0 0 0 0 0 0
Second, at this frequency, the ratio of VOUT to the voltage at +input (Pin 3) has to be 3, which means that the ratio of R11/R12 should be greater than 2.
