µP-Compatible Multiplying

Quad 12-Bit D/A Converter

AD394

FEATURES

Four, complete, 12-bit CMOS DACs with buffer registers

Linearity error: 1ꢀ2 LSB T_MIN, T_MAX(AD394T)

Factory-trimmed gain and offset

Precision output amplifiers for V_OUT

Full four-quadrant multiplication per DAC

Monoticity guaranteed over full temperature range

Fast settling: 15 µs maximum to 1ꢀ2 LSB

Available in MIL-STD-883B

PRODUCT DESCRIPTION

The AD394 contains four 12-bit, high-speed, low power, voltage

output, multiplying digital-to-analog converters in a compact

28-pin hybrid package. The design is based on a proprietary,

latched, 12-bit, CMOS DAC chip, which reduces chip count and

provides high reliability. The AD394 is ideal for systems

requiring digital control of many analog voltages where board

space is at a premium and low power consumption is a neces-

sity. Such applications include automatic test equipment, process

controllers, and vector stroke displays.

The AD394 is laser-trimmed to ±1ꢀ2 ꢁSB maximum differential

and integral linearity (AD394T) and full-scale accuracy of

±±.±0 percent at 20°C. The high initial accuracy is possible

because of the use of precision, laser-trimmed, thin-film scaling

resistors.

PRODUCT HIGHLIGHTS

1. The AD394 offers a dramatic reduction in printed circuit

board space in systems using multiple low power DACs.

CS1

The individual DAC registers are accessed by the

CS4

through

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.

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 (V_REFIN= 1± V) provide a ±1± V bipolar

output range with positive-true offset binary input coding.

3. The output voltage is trimmed to a full-scale accuracy of

±±.±05. Settling time to ±1ꢀ2 ꢁSB is 10 µs maximum.

The AD394 is packaged in a 28-lead ceramic package and is

available for operation over a −00°C to +120°C temperature

range.

4. A maximum gain TC of 0 ppmꢀ°C is achievable.

0. Two- or four-quadrant multiplication can be achieved

simply by applying the appropriate input voltage signal to

the selected DAC's reference (V_REFIN).

6. The AD394TD features guaranteed accuracy and linearity

over the −00°C to +120°C temperature range.
