The MAX40263 is a dual-channel operational amplifier with two channels that can be disabled separately with two individual pins.

The MAX40263 offers a unique combination of high-speed, precision, and low-voltage operation, making it ideally suited for a large number of signal-processing functions such as filtering and amplification of signals in portable and industrial equipment.

The MAX40263's rail-to-rail input/outputs and low noise guarantee maximum dynamic range in demanding applications such as 12- to 14-bit SAR ADC drivers. Unlike traditional rail-to-rail input structures, input crossover distortion is absent due to an optimized input stage with an ultra-quiet charge pump. The input offset voltage is as low as 50μV due to the autocalibration performed during power-up. The device also includes a fast-power-on shutdown mode for further power savings.

The MAX40263 operates from a wide supply range of 1.8V to 5.5V over the -40°C to +125°C temperature range and consumes only 750µA (typ) supply current per channel. It is available in a tiny, 10-pin QFN package.

The MAX40263 is an extension of the MAX44259/60/61/63 and MAX40110/11 families with individual shutdown pins for separate channels.

Product Details

The MAX40263 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 noninverting amplifiers, but it can be adapted to other topologies by changing a few of components. The EV kit comes with a MAX40263AVB+ installed.
