PRODUCT DESCRIPTION

The 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.

The 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
