µP-Compatible Multiplying
Quad 12-Bit D/A Converter
AD394
FEATURES
Four, complete, 12-bit CMOS DACs with buffer registers
Linearity error: ±1/2 LSB TMIN, TMAX (AD394T)
Factory-trimmed gain and offset
Precision output amplifiers for VOUT
Full four-quadrant multiplication per DAC
Monoticity guaranteed over full temperature range
Fast settling: 15 µs maximum to ±1/2 LSB
Available in MIL-STD-883B
PRODUCT DESCRIPTION
The AD394 contains four 12-bit, high-speed, low power, voltage
Ooutput, multiplying digital-to-analog converters in a compact
B28-pin hybrid package. The design is based on a proprietary,
latched, 12-bit, CMOS DAC chip, which reduces chip count and
Sprovides high reliability. The AD394 is ideal for systems
Orequiring digital control of many analog voltages where board
space is at a premium and low power consumption is a neces-
Lsity. Such applications include automatic test equipment, process
Econtrollers, and vector stroke displays.
TEThe AD394 is laser-trimmed to ±1/2 LSB maximum differential
and integral linearity (AD394T) and full-scale accuracy of
±0.05 percent at 25°C. The high initial accuracy is possible
because of the use of precision, laser-trimmed, thin-film scaling
resistors.

PRODUCT HIGHLIGHTS
The individual DAC registers are accessed by the CS1 through
CS4 control pins. These control signals allow any combination
of the DAC select matrix to occur (see Table 3). Once selected,
the DAC is loaded with a single 12-bit wide word. The 12-bit
parallel digital input interfaces to most 12- and 16-bit bus
systems.
1. The AD394 offers a dramatic reduction in printed circuit
board space in systems using multiple low power DACs.
2. Each DAC is independently addressable and provides
versatile control architecture for a simple interface to
microprocessors. All latch enable signals are level-
triggered.
The AD394 outputs (VREFIN = 10 V) provide a ±10 V bipolar
output range with positive-true offset binary input coding.
3. The output voltage is trimmed to a full-scale accuracy of
±0.05%. Settling time to ±1/2 LSB is 15 µs maximum.
The AD394 is packaged in a 28-lead ceramic package and is
available for operation over a −55°C to +125°C temperature
range.
4. A maximum gain TC of 5 ppm/°C is achievable.
5. Two- or four-quadrant multiplication can be achieved
simply by applying the appropriate input voltage signal to
the selected DAC's reference (VREFIN).
6. The AD394TD features guaranteed accuracy and linearity
over the −55°C to +125°C temperature range.
