DESCRIPTION
The LTC
micropower 8-bit current output D/A converters (DACs)
with an output range of 0 A to 10 A for the LTC1329-10
and 0 A to 50 A for the LTC1329-50/LTC1329A-50. The
DAC current output can be biased from – 15V to 2V or
– 15V to 2.5V in 3.3V and 5V systems, respectively. Supply
current is only 95 A for the LTC1329-50/LTC1329A-50
and 75 A for LTC1329-10. A shutdown mode drops the
supply current to 0.2 A.
The LTC1329 can communicate with external circuitry by
using one of three interface modes: standard 3-wire serial
mode and two pulse modes. Upon power-up, the internal
counter resets to 1000 0000B, the DAC output assumes
midrange and the chip is configured in 3-wire or pulse
mode depending on the signal level at CS.
In 3-wire mode, the system MPU can serially transfer 8-bit
data to and from the LTC1329. In pulse mode, the upper
six bits of the DAC output can be programmed for incre-
ment-only (1-wire interface) or increment/decrement
(2-wire interface) operation depending on the signal level
at D
LTC1329 is available in 8-pin SO packages.
