CMOS Analog Switches
General Description
The MAX4610/MAX4611/MAX4612 are quad, low-volt-
age, single-pole/single-throw (SPST) analog switches.
On-resistance (100, max) is matched between switch-
es to 4, max and is flat (4, max) over the specified
signal range. Each switch handles V+ to GND analog
signal levels. Maximum off-leakage current is only 1nA
at TA = +25°C and 2nA at TA = +85°C.
The MAX4610 has four normally open (NO) switches,
and the MAX4611 has four normally closed (NC)
switches. The MAX4612 has two NO switches and two
NC switches. These CMOS switches operate from a
single +2V to +12V supply. All digital inputs have +0.8V
and +2.4V logic thresholds, ensuring TTL/CMOS-logic
compatibility when using a single +5V supply.
