GENERAL DESCRIPTION

PRODUCT HIGHLIGHTS

The AD669 DACPORT^®is a complete 16-bit monolithic D/A

converter with an on-board reference and output amplifier. It is

manufactured on Analog Devices’ BiMOS II process. This pro-

cess allows the fabrication of low power CMOS logic functions

on the same chip as high precision bipolar linear circuitry. The

AD669 chip includes current switches, decoding logic, an output

amplifier, a buried Zener reference and double-buffered latches.

1. The AD669 is a complete voltage output 16-bit DAC with

voltage reference and digital latches on a single IC chip.

2. The internal buried Zener reference is laser trimmed to

10.000 volts with a ±0.2% maximum error. The reference

voltage is also available for external applications.

3. The AD669 is both dc and ac specified. DC specs include

±1 LSB INL error and ±1 LSB DNL error. AC specs include

0.009% THD+ N and 83 dB SNR. The ac specifications

make the AD669 suitable for signal generation applications.

The AD669’s architecture insures 15-bit monotonicity over

temperature. Integral nonlinearity is maintained at ±0.003%,

while differential nonlinearity is ±0.003% max. The on-chip

output amplifier provides a voltage output settling time of 10 µs

to within 1/2 LSB for a full-scale step.

4. The double-buffered latches on the AD669 eliminate data

skew errors while allowing simultaneous updating of DACs in

multi-DAC systems.

Data is loaded into the AD669 in a parallel 16-bit format. The

double-buffered latch structure eliminates data skew errors and

provides for simultaneous updating of DACs in a multi-DAC

system. Three TTL/LSTTL/5 V CMOS compatible signals con-

trol the latches: CS, L1 and LDAC.

5. The output range is a pin-programmable unipolar 0 V to

+10 V or bipolar –10 V to +10 V output. No external compo-

nents are necessary to set the desired output range.

6. The AD669 is available in versions compliant with MIL-

STD-883. Refer to the Analog Devices Military Products

Databook or current AD669/883B data sheet for detailed

specifications.

The output range of the AD669 is pin programmable and can

be set to provide a unipolar output range of 0 V to +10 V or a

bipolar output range of –10 V to +10 V.

The AD669 is available in seven grades: AN and BN versions

are specified from –40°C to +85°C and are packaged in a 28-pin

plastic DIP. The AR and BR versions are specified for –40°C to

+85°C operation and are packaged in a 28-pin SOIC. The SQ

version is specified from –55°C to +125°C and is packaged in a

hermetic 28-pin cerdip package. The AD669 is also available

compliant to MIL-STD-883. Refer to the AD669/883B data

sheet for specifications and test conditions.
