DAC725

® DAC725 Dual 16-Bit DIGITAL-TO-ANALOG CONVERTER FEATURES q COMPLETE DUAL VOUT DAC q DOUBLE-BUFFERED INPUT REGISTER q HIGH-SPEED DATA INPUT: Serial or Parallel q HIGH ACCURACY: ±0.003% Linearity Error q 14-BIT MONOTONICITY OVER TEMPERATURE q PLASTIC PACKAGE q CLEAR INPUT TO SET ZERO OUTPUT DESCRIPTION The DAC725 is a dual 16-bit DAC, complete with internal reference and output op amps. The DAC725 is designed to interface to an 8-bit microprocessor bus, but can also be interfaced to wider buses. The hybrid construction minimizes the digital feedthrough typically associated with products that combine the digital bus interface circuitry with high-accuracy analog circuitry. The 16-bit data word is loaded into either of the DACs in two 8-bit bytes per 16-bit word. The versatility of the control lines allows the data word to be directed to either DAC, in any order. The voltage-out DACs are dedicated to a bipolar output voltage of ±10V. The output is immediately set to 0V when the Clear command is given. This feature, combined with the bus interfacing and complete DAC circuitry, makes the DAC725 ideal for automatic test equipment, power control, servo systems, and robotics applications. 8 D/A Latch 8 16 High Byte Low Byte 16Bit D/A (A) CS (A) 8-Bit Data Bus WR (A) A0 A1 A2 WR (B) 16Bit D/A (B) CLR Control Logic CS (B) High Byte Low Byte 8 D/A Latch 8 16 International Airport Industrial Park Mailing Address: PO Box 11400 Tucson, AZ 85734 Street Address: 6730 S.
