12-Bit, Parallel Input
DIGITAL-TO-ANALOG CONVERTER
DESCRIPTION
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 7
μ
s. The device
consumes 2.5mW (0.5mA at 5V).
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.
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.
