T he LOGDAC AD7112 is a monolithic dual multiplying D/A
converter featuring wide dynamic range and excellent DAC-to-
DAC matching. Both DACs can attenuate an analog input sig-
nal over the range 0 dB to 88.5 dB in 0.375 dB steps. It is
available in skinny 0.3" wide 20-pin DIPs and in 20-terminal
surface mount packages.
T he degree of attenuation in either channel is determined by the
8-bit word applied to the onboard decode logic. T his 8-bit word
is decoded into a 17-bit word which is then loaded into one of
the 17-bit data latches, determined by
DACA
/DACB. T he fine
step resolution over the entire dynamic range is due to the use of
these 17-bit DACs.
T he AD7112 is easily interfaced to a standard 8-bit MPU bus
via an 8-bit data port and standard microprocessor control lines.
It should be noted that the AD7112 is exactly pin-compatible
with the AD7528, an industry standard dual 8-bit multiplying
DAC. T his allows an easy upgrading of existing AD7528 de-
signs which would benefit both from the wider dynamic range
and the finer step resolution offered by the AD7112.
T he AD7112 is fabricated in Linear Compatible CMOS
(LC
2
MOS), an advanced, mixed technology process that com-
bines precision bipolar circuits with low power CMOS logic.

PRODUCT HIGHLIGHT S
1. DAC-to-DAC Matching: Since both of the AD7112 DACs
are fabricated at the same time on the same chip, precise
matching and tracking between the two DACs is inherent.
2. Small Package: T he AD7112 is available in a 20-pin DIP
and a 20-terminal SOIC package.
3. Fast Microprocessor Interface: T he AD7112 has bus inter-
face timing compatible with all modern microprocessors.
