Overview
The DAC8802IPW is a dual, 14-bit, current-output digital-to-analog converter (DAC) designed and manufactured by Texas Instruments. This component operates from a single 2.7 V to 5.5 V supply, making it versatile for various applications. The DAC8802 features an external reference input voltage (VREF) that determines the full-scale output current, and it includes an internal feedback resistor for temperature tracking when used with an external I-to-V precision amplifier. The device is available in a TSSOP-16 package and is suitable for high-speed applications due to its SPI-compatible 3-wire interface and double-buffered registers.
