Description
The ICL7134 combines a four-quadrant multiplying DAC
using thin film resistor and CMOS circuitry with an on-chip
PROM-controlled correction circuit to achieve true 14-bit
linearity without laser trimming.
Microprocessor bus interfacing is eased using standard
memory WRITE cycle timing and control signal use. Two
input buffer registers are separately loaded with the 8 least
significant bits (LS register) and the 6 most significant bits
(MS register). Their contents are then transferred to the
14-bit DAC register, which controls the current switches. The
DAC register can also be loaded directly from the data
inputs, in which case the MS and LS registers are
transparent.
The ICL7134 is available in two versions. The ICL7134U is
programmed for unipolar operation while the ICL7134B is
programmed for bipolar applications. The V
REF
input to the
most significant bit of the DAC is separated from the
reference input to the remainder of the ladder. For unipolar
use, the two reference inputs are tied together, while for
bipolar operation, the polarity of the MSB reference is
reversed, giving the DAC a true 2’s complement input
transfer function. Two resistors which facilitate the reference
inversion are included on the chip, so only an external
op-amp is needed. The PROM is coded to correct for errors
in these resistors as well as the inversion of the MSB.
