DAC7551

BurrĆBrown Products from Texas Instruments DAC7551 SLAS441E – MARCH 2005 – REVISED APRIL 2007 12-Bit, Ultra-Low Glitch, Voltage Output DIGITAL-TO-ANALOG CONVERTER FEATURES Relative Accuracy (INL): ±0.35LSB Ultra-Low Glitch Energy: 0.1nV-s Low Power Operation: 100µA at 2.7V Power-On Reset to Zero Scale Power Supply: 2.7V to 5.5V Single Supply Power-Down: 0.05µA at 2.7V 12-Bit Linearity and Monotonicity Rail-to-Rail Voltage Output Settling Time: 5µs (Max) SPI-Compatible Serial Interface with Schmitt-Trigger Input: Up to 50MHz Daisy-Chain Capability Asynchronous Hardware Clear to Zero Scale Specified Temperature Range: – 40°C to +105°C Small, 2 x 3 mm, 12-Lead SON Package APPLICATIONS Portable, Battery-Powered Instruments Digital Gain and Offset Adjustment Programmable Voltage and Current Sources Programmable Attenuators Industrial Process Control DESCRIPTION The DAC7551 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 operates from a single 2.7V to 5.5V supply. The DAC7551 output amplifiers can drive a 2kΩ, 200pF load rail-to-rail with 5µs settling time; the output range is set using an external voltage reference. The 3-wire serial interface operates at clock rates up to 50MHz and is compatible with SPI™, QSPI™, Microwire™, and DSP interface standards. The parts incorporate a power-on-reset...
