GENERAL DESCRIPTION
The AD7837/AD7847 is a complete, dual, 12-bit multiplying
digital-to-analog converter with output amplifiers on a mono-
lithic CMOS chip. No external user trims are required to
achieve full specified performance.
Both parts are microprocessor compatible, with high speed data
latches and interface logic. The AD7847 accepts 12-bit parallel
data which is loaded into the respective DAC latch using the
WR
input and a separate Chip Select input for each DAC. The
AD7837 has a double-buffered 8-bit bus interface structure
with data loaded to the respective input latch in two write opera-
tions. An asynchronous
LDAC
signal on the AD7837 updates
the DAC latches and analog outputs.
The output amplifiers are capable of developing
±
10 V across a
2 k
load. They are internally compensated with low input off-
set voltage due to laser trimming at wafer level.
The amplifier feedback resistors are internally connected to
V
OUT
on the AD7847.
The AD7837/AD7847 is fabricated in Linear Compatible CMOS
(LC
2
MOS), an advanced, mixed technology process that com-
bines precision bipolar circuits with low power CMOS logic.
A novel low leakage configuration (U.S. Patent No. 4,590,456)
ensures low offset errors over the specified temperature range.
PRODUCT HIGHLIGHTS
1. The AD7837/AD7847 is a dual, 12-bit, voltage-out MDAC
on a single chip. This single chip design offers considerable
space saving and increased reliability over multichip designs.
2. The AD7837 and the AD7847 provide a fast versatile inter-
face to 8-bit or 16-bit data bus structures.
