General Description

The MAX4610/MAX4611/MAX4612 are quad, low-volt-

age, single-pole/single-throw (SPST) analog switches.

On-resistance (100Ω, max) is matched between switch-

es to 4Ω, max and is flat (4Ω, max) over the specified

signal range. Each switch handles V+ to GND analog

signal levels. Maximum off-leakage current is only 1nA

at T

= +25°C and 2nA at T

= +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.

MAX4610/MAX4611/MAX4612 Low-Voltage, Quad, SPST CMOS Analog Switches Protection diodes D1 and D2 also protect against some overvoltage situations. With Figure 1’s circuit, if the supply voltage is below the absolute maximum rating, and if a fault voltage up to the absolute maximum rating is applied to an analog signal pin, no damage will result. single-supply operation with some precautions. The absolute maximum rating for V+ is +13.2V (referenced to GND).
