Maxim's MAX40263 two-channel op-amp has two channels that can be disabled with two separate pins. Operating over a wide supply range from 1.8V to 5.5V in the temperature range -40°C to +125°C, each channel consumes only 750µa of (typical) supply current. It is a small, 10-pin QFN pack. It offers a unique combination of high speed, precision, and low voltage operation, making it ideal for many signal processing functions, such as filtering and amplifying signals in portable and industrial equipment.

It offers a unique combination of high speed, precision, and low voltage operation, making it ideal for many signal processing functions, such as filtering and amplifying signals in portable and industrial equipment.
The MAX40263EVKIT# Evaluation Kit (EV Kit) provides a proven design for evaluating the MAX40263 low-noise, low-power, low-bias current dual operational amplifier with an independent shut-off feature for each channel in the 10-pin QFN package. The EV kit circuit is pre-configured as a non-inverter amplifier, but it can be adapted to other topologies by changing some components. EV kit comes with MAX40263AVB+ installation.
