GENERAL DESCRIPTION
The AD7237A/AD7247A is an enhanced version of the industry standard
AD7237/AD7247. Improvements include operation from 12 V to 15 V supplies,
faster interface times and better reference variations with VDD. Additional
features include faster settling times.
The AD7237A/AD7247A is a complete, dual, 12-bit, voltage output digital-to-
analog converter with output amplifiers and Zener voltage reference on a
monolithic 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 AD7247A 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 AD7237A has a double buffered interface structure and an
8-bit wide data bus with data loaded to the respective input latch in two
write operations. An asynchronous LDAC signal on the AD7237A updates the DAC
latches and analog outputs.
A REF OUT/REF IN function is provided which allows either the on-chip 5 V
reference or an external reference to be used as a reference voltage for the
part. For single supply operation, two output ranges of 0 V to +5 V and 0 V to
+10 V are available, while these two ranges plus an additional ±5 V range are
available with dual supplies. The output amplifiers are capable of developing
+10 V across a 2 kΩ load to GND.
The AD7237A/AD7247A is fabricated in Linear Compatible CMOS (LC2MOS), an
advanced, mixed technology process that combines precision bipolar circuits
with low power CMOS logic. Both parts are available in a 24-pin, 0.3" wide
plastic and hermetic dual-in-line package (DIP) and are also packaged in a
24-lead small outline (SOIC) package.
