Low-Voltage, Single-Supply Analog Multiplexers/Switches
General Description
The MAX4524L/MAX4525L are low-voltage, single-supply CMOS analog switches configured as a 4-channel multiplexer/demultiplexer (MAX4524L) and a doublepole/double-throw (DPDT) switch (MAX4525L). The MAX4524L/MAX4525L have an inhibit input to simultaneously open all switches. These devices operate from a single supply of +2V to +12V. They are optimized for operation with a +12V supply. The on-resistance is 100 with a +12V supply. Each switch can handle Rail-to-Rail analog signals. Off-leakage current measures only 2nA at +25C. All digital inputs have 0.8V to 2.0V logic thresholds to ensure TTL/CMOSlogic compatibility when using a +12V supply. o +3V Logic-Compatible Inputs (VIH = 2.0V, VIL = 0.8V) o +2V to +12V Supply Operation o 100 On-Resistance with +12V Supply o Guaranteed 10 On-Resistance Match at +12V o Guaranteed 2nA Maximum Off-Leakage at +12V o TTL/CMOS-Logic Compatible o Tiny 10-Pin TDFN (3mm x 3mm) and 10-Pin MAX Packages

The TDFN package is production tested at TA = +25C. Limits over temperature are guaranteed by design. The algebraic convention used in this data sheet is where the most negative value is a minimum column. RON = RON(MAX) - RON(MIN). Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the specified analog signal ranges. Note 6: Leakage parameters are 100% tested at maximum-rated hot operating temperature and guaranteed by design at TA = +25C. Note 7: Guaranteed by design, not production tested.

Low-Voltage, Single-Supply Analog Multiplexers/Switches MAX4524L/MAX4525L
Detailed Description
The MAX4524L/MAX4525L are low-voltage, single-supply CMOS analog switches that operate from a single supply of +2V to +12V. Operation with a +12V supply optimizes the performance by reducing their on-resistance to 100. The MAX4524L is configured as a 4channel multiplexer/demultiplexer and the MAX4525L is a double-pole/double-throw (DPDT) switch. These devices have an inhibit input (INH) to simultaneously open all signal paths. Each switch can handle rail-torail analog signals. The off-leakage current is typically only 0.1nA at +25C and 10nA (max) over temperature. All digital inputs have 0.8V to 2.0V logic-level thresholds, ensuring TTL/CMOS-logic compatibility when using a single +12V supply. analog signal exceeds V+ or goes below GND, one of these diodes conducts. During normal operation, these reverse-biased ESD diodes leak, forming the only current drawn from V+ or GND. Virtually all the analog leakage current comes from the ESD diodes. Although the ESD diodes on a given signal pin are identical, and therefore fairly well balanced, they are reverse biased differently. Each is biased by either V+ or GND and the analog signal. This means that leakage varies as the signal varies. The difference in the two diode leakages to the V+ and GND pins constitutes the analog signalpath leakage current. All analog leakage current flows between each pin and one of the supply terminals, not to the other switch terminal. This is why both sides of a given switch can show leakage currents of either the same or opposite polarity. There is no connection between the analog signal paths and GND. V+ and GND power the internal logic and logic-level translators, and set both the input and output logic limits. The logic-level translators convert the logic levels into switched V+ and GND signals to drive the gates of the analog signals. This drive signal is the only connection between the logic supplies (and signals) and the analog supplies.
Applications Information
Power-Supply Considerations
The MAX4524L/MAX4525Ls' construction is typical of most CMOS analog switches. The supply input, V+, is used to power the internal CMOS switches and set the limits of the analog voltage on any switch. Reverse ESD protection diodes are internally connected between each analog signal pin and both V+ and GND. If any
