GENERAL DESCRIPTION

The AD669 DACPORT

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.

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 s

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

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.

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.
