XR-9201
XR-9201 is 8-Bit Microprocessor Compatible DigitalaTo-Analog Converter manufactured by Exar.
DESCRIPTION
FUNCTIONAL BLOCK DIAGRAM
The XR-9201 is a monolithic 8-Bit ",p patible digitalto-analog converter with differential current outputs. It contains an internal data latch, making it suitable for interfacing with microprocessors. The chip contains a stable voltage reference (2.0 V Nominal) which is externally adjustable and can be used as a reference for other D/A and AID converters.
The XR-9201 features non-linearity of ± V2 LSB maximum (± .19% of full scale current). The internal voltage reference maintains a temperature coefficient of SO ppm/o C.
