AD3542RBCPZ12-RL7

AD3542RBCPZ12-RL7 is a low drift, dual channel, ultra-fast, 12bit accuracy, voltage output digital-to-analogue converter (DAC) that can be configured in multiple voltage span ranges. The AD3542R operates with a fixed 2.5V reference. This DAC incorporates three drift-compensating feedback resistors for the internal trans-impedance amplifier (TIA) that scales the output voltage. The serial peripheral interface (SPI) can be configured in dual synchronous SPI, dual SPI and single SPI (classic SPI) mode with single date rate (SDR) or double data rate (DDR), with logical levels from 1.2V to 1.8V. Applications include instrumentation, hardware in the loop, process control equipment, medical devices, automated test equipment, data acquisition system, programmable voltage sources, optical communications.
