| 16V, 180A Low Power, Low Noise, Single Precision CMOS Rail-to-Rail Output Operational Amplifiers Preliminary Technical Data FEATURES Lower Power at High Voltage: 180 A typ Low offset voltage: 100 V Low input bias current: 300 fA Max Low Voltage Noise: 21nV/Hz @ 10kHz 23nV/Hz @ 1kHz Single-supply operation: 5V to 16V Dual-supply operation: 2.5V to 8V Output Drive 10mA Unity Gain Stable AD8663 PIN CONFIGURATIONS APPLICATIONS Medical Equipment Precision References Buffer / Level Shifting Portable Operated Systems Sensors Photodiode Amplification ADC Drivers GENERAL DESCRIPTION The AD8663 is single rail-to-rail output single/dual supply amplifiers that use Analog Devices' patented DigiTrim(R) trimming technique to achieve low offset voltage, 300V over the common mode range. The AD8663 family features an extended operating range with supply voltage up to 16V for low power operation with ISY of < 325A over the extended industrial temperature. These devices are designed for low noise at higher voltages, 21nV/Hz at 10kHz and 23 nV/Hz at 1 kHz. They also feature low input bias currents of 300fA and 10mA output drive. The combination of low supply currents, low offsets, very low input bias currents, and wide supply range make these amplifiers useful in a wide variety of low power applications. Systems utilizing DC to low frequency measurements, or high impedance sensors, such as photo-diodes benefit from the combination of low input bias current, low noise, low offset and drive current. The wide operating voltage range matches today's high performance ADCs and DACs. Medical monitoring equipment can take advantage of the low voltage noise, high input impedance, low voltage and current noise. The AD8663 is specified over the extended industrial (-40C to +125C) temperature range. Rev. PrA Information furnished by Analog Devices is believed to be accurate and reliable.

This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. THERMAL RESISTANCE JA is specified for the worst-case conditions, that is, a device soldered in circuit board for surface-mount packages. Table 2. Package Type 8-Lead SOIC_N 8-Lead LFCSP_VD JA 121 75 JC 43 18 Unit C/W C/W ESD 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 this product 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.
