CMOS 8 Bit Multiplying D/A Converter
General Description
The MX7523 is high performance multiplying 8 bit
digital-to-analog converter (DAC). Low power CMOS
technology and low cost make it suitable for a wide
range of analog data acquisition and control appli-
cations.
Thin-film resistors assure 8 bit resolution with up to
10 bit linearity (L grade) over the full operating tem-
perature range, In addition, all digital inputs are
compatible with CMOS logic levels.
Maxim's MX7523 is electrically and pin compatible
with the Analog Devices AD7523 and is available in a
standard width 16-Iead DIP as well as small outline
package.
