DAC7634

BurrĆBrown Products from Texas Instruments DAC7634 SBAS134B – JULY 2004 – REVISED DECEMBER 2005 16-BIT, QUAD VOLTAGE OUTPUT DIGITAL-TO-ANALOG CONVERTER FEATURES Low Power: 10 mW Unipolar or Bipolar Operation Settling Time: 10 µs to 0.003% 15-Bit Linearity and Monotonicity: –40°C to 85°C Programmable Reset to Mid-Scale or Zero-Scale Double-Buffered Data Inputs APPLICATIONS Process Control Closed-Loop Servo-Control Motor Control Data Acquisition Systems DAC-Per-Pin Programmers DESCRIPTION The DAC7634 is a 16-bit, quad voltage output, digitalto-analog converter with specified 15-bit monotonic performance over the specified temperature range. It accepts 24-bit serial input data, has double-buffered DAC input logic (allowing simultaneous update of all DACs), and provides a serial data output for daisy-chaining multiple DACs. Programmable asynchronous reset clears all registers to a mid-scale code of 8000H or to a zero-scale of 0000H. The DAC7634 can operate from a single 5-V supply or from 5-V and –5 V supplies. Low power and small size per DAC make the DAC7634 ideal for automatic test equipment, DAC-per-pin programmers, data acquisition systems, and closed-loop servo-control. The DAC7634 is available in a 48-lead SSOP package and offers specifications over the –40°C to 85°C temperature range.
