GENERAL DESCRIPTION
The AD5332/AD5333/AD5342/AD5343 are dual 8-, 10-, and
12-bit DACs. They operate from a 2.5 V to 5.5 V supply con-
suming just 230
μ
A at 3 V, and feature a power-down pin,
PD
that further reduces the current to 80 nA. These devices incor-
porate an on-chip output buffer that can drive the output to
both supply rails, while the AD5333 and AD5342 allow a choice
of buffered or unbuffered reference input.
The AD5332/AD5333/AD5342/AD5343 have a parallel interface.
CS
selects the device and data is loaded into the input registers
on the rising edge of
WR
.
The GAIN pin on the AD5333 and AD5342 allows the output
range to be set at 0 V to V
REF
or 0 V to 2
×
V
REF
.
Input data to the DACs is double-buffered, allowing simultaneous
update of multiple DACs in a system using the
LDAC
pin.
An asynchronous
CLR
input is also provided, which resets the
contents of the Input Register and the DAC Register to all zeros.
These devices also incorporate a power-on reset circuit that ensures
that the DAC output powers on to 0 V and remains there until
valid data is written to the device.
The AD5332/AD5333/AD5342/AD5343 are available in Thin
Shrink Small Outline Packages (TSSOP).
