Overview
The DAC7564ICPWR is a 12-bit, quad-channel, ultra-low glitch, voltage-output digital-to-analog converter (DAC) produced by Texas Instruments. This device is designed for low-power applications and features a 2.5V internal reference with high accuracy and low temperature drift. It is packaged in a TSSOP-16 package and is suitable for a wide range of applications, including portable instrumentation, closed-loop servo-control, and data acquisition systems. The DAC7564ICPWR is known for its high linearity, minimal code-to-code transient voltages (glitch), and versatile 3-wire serial interface compatible with standard SPI, QSPI, Microwire, and DSP interfaces.
