DAC8544IPFB TI DAC | 48-TQFP (7x7) | 16-Bit, Quad, Low-Power

Product Overview

The DAC8544IPFB is a 16-bit, quad-channel, low-power, voltage-output digital-to-analog converter (DAC) from Texas Instruments. It operates from a single 2.7V to 5.5V supply and features a flexible serial interface compatible with SPI, QSPI, Microwire, and DSP interfaces. The device includes a power-on reset circuit that ensures the DAC outputs power up at zero scale or midscale, and a power-down feature that reduces current consumption to typically 0.5 µA at 5V. The DAC8544IPFB is available in a compact 48-pin TQFP package (7x7 mm) and is specified over the extended industrial temperature range of -40°C to +105°C.
