® DAC 761 2 Dual, 12-Bit Serial Input DIGITAL-TO-ANALOG CONVERTER Features q LOW POWER: 3.7m W q FAST SETTLING: 7µs to 1 LSB q 1m V LSB WITH 4.095V FULL-SCALE RANGE q PLETE WITH REFERENCE q 12-BIT LINEARITY AND MONOTONICITY OVER INDUSTRIAL TEMP RANGE q 3-WIRE INTERFACE: Up to 20MHz Clock q SMALL PACKAGE: 8-Lead SOIC DESCRIPTION The DAC7612 is a dual, 12-bit digital-to-analog converter (DAC) with guaranteed 12-bit monotonicity performance over the industrial temperature range. It requires a single +5V supply and contains an input shift register, latch, 2.435V reference, a dual DAC, and high speed rail-to-rail output amplifiers. For a fullscale step, each output will settle to 1 LSB within 7µs while only consuming 3.7m W. The synchronous serial interface is patible with a wide variety of DSPs and microcontrollers. Clock (CLK), Serial Data In (SDI), Chip Select (CS) and Load DACs (LOADDACS) prise the serial interface. The DAC7612 is available in an 8-lead SOIC package and is fully specified over the industrial temperature range of - 40°C to +85°C.
