Overview
The DAC8554IPWR is a 16-bit, quad-channel, voltage output digital-to-analog converter (DAC) produced by Texas Instruments. This device is designed for low-power operation and features a flexible serial host interface. It offers exceptional linearity, monotonicity, and ultra-low glitch energy, making it suitable for a variety of applications requiring high precision and low power consumption.
The DAC8554IPWR operates within a supply range of 2.7V to 5.5V and supports a standard 3-wire serial interface capable of operating at clock frequencies up to 50MHz. Each channel has an on-chip precision output amplifier allowing rail-to-rail output swing. The device also includes a power-on reset circuit that ensures the DAC outputs power up at zero-scale and remain there until a valid write takes place.
