DAC1020/DAC1021/DAC1022
10-Bit Binary Multiplying D/A Converter
DAC1220/DAC1222
12-Bit Binary Multiplying D/A Converter
General Description
The DAC1020 and the DAC1220 are, respectively, 10 and
12-bit binary multiplying digital-to-analog converters. A de-
posited thin film R-2R resistor ladder divides the reference
current and provides the circuit with excellent temperature
tracking characteristics (0.0002%/
§
C linearity error temper-
ature coefficient maximum). The circuit uses CMOS current
switches and drive circuitry to achieve low power consump-
tion (30 mW max) and low output leakages (200 nA max).
The digital inputs are compatible with DTL/TTL logic levels
as well as full CMOS logic level swings. This part, combined
with an external amplifier and voltage reference, can be
used as a standard D/A converter; however, it is also very
attractive for multiplying applications (such as digitally con-
trolled gain blocks) since its linearity error is essentially in-
dependent of the voltage reference. All inputs are protected
from damage due to static discharge by diode clamps to V
a
and ground.
This part is available with 10-bit (0.05%), 9-bit (0.10%), and
8-bit (0.20%) non-linearity guaranteed over temperature
(note
DAC1021 and DAC1022 are direct replacements for the 10-
bit resolution AD7520 and AD7530 and equivalent to the
AD7533 family. The DAC1220 and DAC1222 are direct re-
placements for the 12-bit resolution AD7521 and AD7531
family.
