12-Bit, Parallel Input

DIGITAL-TO-ANALOG CONVERTER

DESCRIPTION

FEATURES

The DAC7621 is a 12-bit digital-to-analog converter

(DAC) with guaranteed 12-bit monotonicity perfor-

mance over the industrial temperature range. It re-

quires a single +5V supply and contains an input

rail-to-rail output amplifier. For a full-scale step, the

output will settle to 1 LSB within 7µs. The device

consumes 2.5mW (0.5mA at 5V).

● LOW POWER: 2.5mW

● FAST SETTLING: 7µs to 1 LSB

● 1mV LSB WITH 4.095V FULL-SCALE

RANGE

● COMPLETE WITH REFERENCE

● 12-BIT LINEARITY AND MONOTONICITY

OVER INDUSTRIAL TEMP RANGE

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 struc-

ture 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.

● ASYNCHRONOUS RESET TO 0V

APPLICATIONS

● PROCESS CONTROL

● DATA ACQUISITION SYSTEMS

● CLOSED-LOOP SERVO-CONTROL

● PC PERIPHERALS

The DAC7621 is available in a 20-lead SSOP package

and is fully specified over the industrial temperature

range of –40°C to +85°C.

● PORTABLE INSTRUMENTATION
