Description

General part information

DAC7551-Q1 Series

The DAC7551-Q1 device is a single-channel, voltage-output digital-to-analog converter (DAC) with exceptional linearity and monotonicity, and a proprietary architecture that minimizes glitch energy. The low-power DAC7551-Q1 device operates from a single 2.7- to 5.5-V supply. The DAC7551-Q1 output amplifiers can drive a 2-kΩ, 200-pF load rail-to-rail with 5-µs settling time. The output range is set using an external voltage reference.

The 3-wire serial interface operates at clock rates up to 50 MHz and is compatible with SPI™, QSPI™, microwire, and DSP interface standards. The device incorporates a power-on-reset (POR) circuit to ensure that the DAC output powers up to 0 V and remains at that voltage until a valid write cycle to the device occurs. The device contains a power-down feature that reduces the current consumption of the device to under 2 µA.

Small size and low-power operation make the DAC7551-Q1 device ideally suited for battery-operated, portable applications. The power consumption is typically 0.5 mW at 5 V, 0.23 mW at 3 V, and reduces to 1 µW in power-down mode.
