DAC8234SPFB TI DAC | 48-TQFP (7x7) | 4-Ch, 12-Bit, Serial Input

Product Overview

The DAC8234SPFB is a quad-channel, 12-bit, serial-input, voltage-output digital-to-analog converter (DAC) from Texas Instruments. It operates from a single +2.7V to +5.5V supply and features a low-power consumption of 0.5mW per channel at 3V. The device includes a power-on reset circuit that ensures the DAC outputs power up to zero volts and remains there until a valid write takes place. The DAC8234SPFB is available in a compact 48-pin TQFP package (7x7mm), making it ideal for space-constrained applications.
