D/A Converter
PRODUCT DESCRIPTIONThe AD75004 contains four complete, voltage output, 12-bit
digital-to-analog converters, a high stability bandgap reference,
and double-buffered input latches on a single chip. The convert-
ers use 12 precision high speed bipolar current steering switches
and laser-trimmed thin-film resistor networks to provide fast
settling time and high accuracy.
Microprocessor compatibility is achieved by the on-chip
double-buffered latches. The design of the input latches allows
direct interface to 8-bit buses. The 12 bits of data from the first
rank of latches can then be transferred to the second rank,
avoiding generation of spurious analog output values. The latch
responds to strobe pulses as short as 50 ns, allowing use with
fast microprocessors.
The functional completeness and high performance of the
AD75004 results from a combination of advanced switch de-
sign, the BiMOS II fabrication process, and proven laser trim-
ming technology. BiMOS II is an epitaxial BiCMOS process
optimized for analog and converter functions. The AD75004 is
trimmed at the wafer level and is specified to ±1/2 LSB maxi-
mum linearity error at 25°C and ±3/4 LSB over the full operat-
ing temperature range. The on-chip output amplifiers provide
an output range of ±5 V, with 1 LSB equal to 2.44 mV.

8-Bit Microprocessor Interface
24-Pin PDIP or 28-Lead PLCC PackageThe bandgap reference on the chip has low noise, long term
stability and temperature drift characteristics comparable to
discrete reference diodes. The absolute value of the reference is
laser trimmed to +5.00 V with 0.6% maximum error. Its tem-
perature coefficient is also laser trimmed.
Typical full-scale gain TC is 15 ppm/°C. With guaranteed
monotonicity over the full temperature range, the AD75004 is
well suited for wide temperature range performance.
AD75004–SPECIFICATIONS(TA = +258C, 612.0 V power supplies unless otherwise noted)NOTESGain and bipolar zero errors are measured using internal voltage reference and include its errors.Digital crosstalk is defined as the change in any one output’s steady state value as a result of any other output being driven from VOUTMIN to VOUTMAX into a
2 kΩ || 500 pF load by means of varying the digital input code.The internal voltage reference is intended to drive on-chip only; buffer it if using it externally.All minimum and maximum specifications are guaranteed, and specifications shown in boldface are tested on all production units at final electrical test. Results from
those tests are used to calculate outgoing quality levels.

*Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress
ratings only and functional operation of the device at these or any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
TRUTH TABLENOTE
*The A1 and A0 inputs specify the relevant channel.
A0ChannelCAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the AD75004 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
