DIGITAL-TO-ANALOG CONVERTER
FEATURES DESCRIPTION в—Џ LOW POWER: 2.5mW
в—Џ FAST SETTLING: 7Вµs to 1 LSB The DAC7621 is a 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
register, latch, 2.435V reference, DAC, and high speed
rail-to-rail output amplifier. For a full-scale step, the
output will settle to 1 LSB within 7Вµs. The device
consumes 2.5mW (0.5mA at 5V). в—Џ 1mV LSB WITH 4.095V FULL-SCALE
RANGE
в—Џ COMPLETE WITH REFERENCE
в—Џ 12-BIT LINEARITY AND MONOTONICITY
OVER INDUSTRIAL TEMP RANGE
в—Џ ASYNCHRONOUS RESET TO 0V The parallel interface is compatible with a wide variety
of microcontrollers. The DAC7621 accepts a 12-bit
parallel word, has a double-buffered input logic structure and provides data readback. In addition, two
control pins provide a chip select (CS) function and
asynchronous clear (CLR) input. The CLR input can
be used to ensure that the DAC7621 output is 0V on
power-up or as required by the application. APPLICATIONS
