GENERAL DESCRIPTION
The AD7534 is a 14-bit monolithic CMOS D/A converter which
uses thirAilm resistors and laser trimming to achieve excellent
linearity.
The device is configured to accept righr-iusMed dam in two
bytes from an 8-bit data bus. Standard Chip Select and Memory
Write logic is used to access the DAC. Address lines M and Al
control internal register loading and transfer.
A novel low leakage configuration (patent pending) enables the
AD7534 to exhibit excellent autput leakage current characteristics
over the specified temperature range.
The device is fully protected against CMOS "latch up" phenomena
and does not require the use of exteml Schottky diodes or the
we of l FET Input op amp. The AD7534 is nunufactured
using the Linear Compatible CMOS (LC’MOS) process. It is
speed compatible with most microprocessors and accepts TTL
or CMOS logic level inputs.

PRODUCT HIGHLIGHTS
1. Guaranteed Montonicity
The AD7534 is guaramecd monotonic to Mobil: over the full
temperature range for all grades.
2. Low Output Leakage
By tying Vss (Pin 20) to a negative voltage, it is possible to
achieve a low output leakage current at high temperatures.
3. Microprocessor Compatibility
High speed input control (rruw CMOS compatible) allows
direct interfacing to most of the popular 8-bit and 16-bit
microprocessors.
4. Monolithic Construction
For increased reliability and reduced package size - 0.3"
20-pin DIP and 20-terminal surface mount package.
