The AD3541R operates with a fixed 2.5 V reference. Each DAC incorporates three drift pensating 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). Table 1. Related Devices Part No. Description LTC6655 ADR4525 AD3552R AD3551R AD3542R 0.25 ppm...
