Overview
The DAC8871SPW is a 16-bit, single-channel, serial input, voltage output digital-to-analog converter (DAC) produced by Texas Instruments. This device is designed to provide high accuracy, low noise, and fast settling times, making it suitable for a variety of applications. The DAC8871 operates over a wide temperature range of -40°C to 105°C and features a high-speed SPI interface up to 50MHz. The output range is determined by the reference voltage, allowing for unipolar or bipolar outputs up to ±18V. The device is available in a 16-pin TSSOP package, which is compact and suitable for space-constrained designs.
