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  
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 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.
