Overview
The DAC8560IADGKRG4 is a 16-bit, ultra-low glitch, voltage output digital-to-analog converter (DAC) produced by Texas Instruments. This device is designed for low-power operation and features an internal 2.5-V reference voltage with high accuracy and stability. The DAC8560 is monotonic over the entire temperature range and offers excellent linearity, minimizing undesired code-to-code transient voltages (glitch). It is highly suitable for applications requiring precise analog output and low power consumption, making it ideal for portable, battery-operated equipment.
