Overview
The DAC8534IPW is a quad-channel, 16-bit Digital-to-Analog Converter (DAC) manufactured by Texas Instruments. This device is designed for low-power operation and features a flexible serial host interface. Each on-chip precision output amplifier allows for rail-to-rail output swing over a supply range of 2.7V to 5.5V. The DAC8534 supports a standard 3-wire serial interface capable of operating with input data clock frequencies up to 30MHz. It is particularly suited for portable battery-operated equipment and other low-power applications due to its microPOWER operation and power-down features.
