Overview
The DAC7564IAPW is a low-power, voltage-output, four-channel, 12-bit digital-to-analog converter (DAC) produced by Texas Instruments. This device features a 2.5V internal reference with a temperature drift of 2ppm/°C, providing a full-scale output voltage range of 2.5V. It is designed for high accuracy and linearity, minimizing undesired code-to-code transient voltages (glitch). The DAC7564IAPW is ideal for applications requiring low power consumption and a small footprint, making it suitable for portable, battery-operated equipment.
