DAC11001BPFBT

Digital To Analog Converters Overview

The DAC11001B is a 20-bit, low-noise, ultra-low harmonic distortion, fast-settling, high-voltage-output digital-to-analog converter (DAC) manufactured by Texas Instruments. It features a single-channel unbuffered voltage output with integrated precision feedback resistors. The device supports flexible output ranges from VREFPF to VREFNF and includes an enhanced deglitch circuit for code-independent ultra-low glitch impulse of 1 nV-s. It operates with a 50-MHz, 4-wire SPI-compatible interface supporting readback and daisy-chain modes. The DAC11001B is specified monotonic by design with 1-LSB DNL and INL maximums. It functions within a temperature range of –40°C to +125°C and is available in a 48-pin TQFP package.
