GENERAL DESCRIPTION
The AD7538 is a 14-bit monolithic CMOS digital-to-analog
converter (DAC) that uses laser trimmed thin-film resistors to
achieve excellent linearity.
The DAC is loaded by a single 14-bit wide word using standard
chip select and memory write logic. Double buffering, which is
optional using LDAC, allows simultaneous updates in a system
containing multiple AD7538s.
A novel low leakage configuration enables the AD7538 to
exhibit excellent output leakage current characteristics over
the specified temperature range.
The AD7538 is manufactured using the linear-compatible
CMOS (LC2MOS) process. It is speed compatible with most
microprocessors and accepts TTL or CMOS logic level inputs.
PRODUCT HIGHLIGHTS
1.
Guaranteed Monotonicity.
The AD7538 is guaranteed monotonic to 14-bits over the
full temperature range for all grades.
2.
Low Cost.
The AD7538, with its 14-bit dynamic range, affords a low
cost solution for 12-bit system upgrades.
3.
Small Package Size.
The AD7538 is packaged in a small 24-pin, 0.3" DIP and a
24-pin SOIC.
4.
Low Output Leakage.
By tying VSS (Pin 24) to a negative voltage, it is possible to
achieve a low output leakage current at high temperatures.
5.
Wide Power Supply Tolerance.
The device operates on a +12 V to +15 V VDD, with a ±5%
tolerance on this nominal figure. All specifications are
guaranteed over this range.
