AD3541R - Analog Devices

AD3541R Multi-IO SPI DAC

The AD3541R is a low drift, single channel, ultra-fast, 12-/16-bit accuracy, voltage output digital-to-analog converter (DAC) that can be configured in multiple voltage span ranges. The AD3541R operates with a fixed 2.5 V reference. Each DAC incorporates three drift compensating feedback resistors for the internal transimpedance amplifier (TIA) that scales.
