DESCRIPTION
16-/14-/12-Bit V
OUT
DACs in
3mm × 3mm DFN
The LTC
®
2641/LTC2642 are families of 16-, 14- and 12-bit
unbuffered voltage output DACs. These DACs operate from
a single 2.7V to 5.5V supply and are guaranteed mono
-
tonic over temperature. The LTC2641A-16/LTC2642A-16
provide 16-bit performance (±1LSB INL and ±1LSB DNL)
over temperature. Unbuffered DAC outputs result in low
supply current of 120µA and a low offset error of ±1LSB.
Both the LTC2641 and LTC2642 feature a reference input
range of 2V to V
DD
. V
OUT
swings from 0V to V
REF
. For
bipolar operation, the LTC2642 includes matched scaling
resistors for use with an external precision op amp (such
as the LT1678), generating a ±V
REF
output swing at R
FB
.
The LTC2641/LTC2642 use a simple SPI/MICROWIRE
compatible 3-wire serial interface which can be operated
at clock rates up to 50MHz and can interface directly
with optocouplers for applications requiring isolation. A
power-on reset circuit clears the LTC2641’s DAC output
to zero scale and the LTC2642’s DAC output to midscale
when power is initially applied. A logic low on the CLR pin
asynchronously clears the DAC to
zero scale (
LTC2641)
or midscale (LTC2642). These DACs are all specified over
the commercial and industrial ranges.
