MAX40263 Dual Op Amp

Analog Devices' MAX40263 dual-channel operational amplifier has two channels that can be disabled separately with two individual pins. 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 MAX40263 operates from a wide supply range of 1.8 V to 5.5 V over the -40°C to +125°C temperature range and consumes only 750 µA (typ) supply current per channel. It is available in a tiny, 10-pin QFN package.

The MAX40263EVKIT# evaluation kit (EV kit) provides a proven design to evaluate the MAX40263 low-noise, low-power, low-bias-current dual operational amplifier with independent shutdown for each channel in a 10-pin QFN package. The EV kit circuit is preconfigured as a noninverting amplifier, but it can be adapted to other topologies by changing a few components. The EV kit comes with a MAX40263AVB+ installed.
