Description
AI
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 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 AD3541RBCPZ16 (hereafter referred to as AD3541R-16) can operate in fast mode for maximum speed or precision mode for maximum accuracy. The AD3541RBCPZ12 (hereafter referred to as AD3541R-12) has a single operation mode.The serial peripheral interface (SPI) can be configured in 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 AD3541R 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
