DAC7617 DAC7617 DAC7617 ® www.ti.com Quad, Serial Input, 12-Bit, Voltage Output DIGITAL-TO-ANALOG CONVERTER FEATURES q LOW POWER: 3mW q SETTLING TIME: 10µs to 0.012% q 12-BIT LINEARITY AND MONOTONICITY: –40°C to +85°C q DOUBLE-BUFFERED DATA INPUTS q SO-16 or SSOP-20 PACKAGES q SINGLE-SUPPLY +3V OPERATION DESCRIPTION The DAC7617 is a quad, serial input, 12-bit, voltage output Digital-to-Analog Converter (DAC) with guaranteed 12-bit monotonic performance over the –40°C to +85°C temperature range. An asynchronous reset clears all registers to either mid-scale (800H) or zeroscale (000H), selectable via the RESETSEL pin. The individual DAC inputs are double buffered to allow APPLICATIONS q PROCESS CONTROL q ATE PIN ELECTRONICS q CLOSED-LOOP SERVO-CONTROL q MOTOR CONTROL q DATA ACQUISITION SYSTEMS q DAC-PER-PIN PROGRAMMERS for simultaneous update of all DAC outputs. The device is powered from a single +3V supply. Low power and small size makes the DAC7617 ideal for automatic test equipment, DAC-per-pin programmers, data acquisition systems, and closed-loop servocontrol. The device is available in SO-16 and SSOP-20 packages and is guaranteed over the –40°C to +85°C temperature range.
