12-Bit Quad Voltage OutputDIGITAL-TO-ANALOG CONVERTER®DAC7724DAC7725DESCRIPTIONThe DAC7724 and DAC7725 are 12-bit quad voltageoutput digital-to-analog converters with guaranteed12-bit monotonic performance over the specified tem-perature range. They accept 12-bit parallel input data,have double-buffered DAC input logic (allowing simul-taneous update of all DACs), and provide a readbackmode of the internal input registers. An asynchronousreset clears all registers to a mid-scale code of 800H(DAC7724) or to a zero-scale of 000H (DAC7725). TheDAC7724 and DAC7725 can operate from a single+15V supply, or from +15V and –15V supplies.Low power and small size per DAC make the DAC7724and DAC7725 ideal for automatic test equipment,DAC-per-pin programmers, data acquisition systems,and closed-loop servo-control. The DAC7724 andDAC7725 are available in a PLCC-28 or a SO-28package, and offer guaranteed specifications over the–40°C to +85°C temperature range.FEATURES● LOW POWER: 250mW max● SINGLE SUPPLY OUTPUT RANGE: +10V● DUAL SUPPLY OUTPUT RANGE: ±10V● SETTLING TIME: 10µs to 0.012%● 12-BIT LINEARITY AND MONOTONICITY:–40°C to +85°C● RESET TO MID-SCALE (DAC7724) ORZERO-SCALE (DAC7725)● DATA READBACK● DOUBLE-BUFFERED DATA INPUTSAPPLICATIONS● PROCESS CONTROL● CLOSED-LOOP SERVO-CONTROL● MOTOR CONTROL● DATA ACQUISITION SYSTEMS© 1999 Burr-Brown Corporation PDS-1517B Printed in U.S.A.
