MAXIM MAX4524L, MAX4525L User Manual

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.

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 +25°C 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.
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
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.
