Description

The AD3542R is a low drift, dual channel, ultra-fast, 12-/16-bit accuracy, voltage output digital-to-analog converter (DAC) that can be configured in multiple voltage span ranges. The AD3542R operates with a fixed 2.5 V reference.Each DAC incorporates three drift compensating feedback resistors for the internal transimpedance amplifier (TIA) that scales the output voltage. The device has five preconfigured output voltage ranges: 0 V to 2.5 V, 0 V to 5 V, 0 V to 10 V, −5 V to +5 V, and −2.5 V to +7.5 V.The AD3542RBCPZ16 (hereafter referred to as AD3542R-16) can operate in fast mode for maximum speed or precision mode for maximum accuracy. The AD3542RBCPZ12 (hereafter referred to as AD3542R-12) has a single operation mode.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 1.2 V to 1.8 V.The AD3542R is specified over the extended industrial temperature range (–40°C to +105°C).APPLICATIONSInstrumentationHardware in the loopProcess control equipmentMedical devicesAutomated test equipmentData acquisition systemProgrammable voltage sourcesOptical communications
