Description

This is Quad 8-Bit Multiplying CMOS D/A Converter with Memory. a FEATURES Four DACs in a 28 Pin, 0.6 Inch Wide DIP or 28-Pin JEDEC Plastic Chip Carrier 1, 4 LSB Endpoint Linearity Guaranteed Monotonic DACs Matched to Within 1% Microprocessor Compatible Read, Write Capability (with Memory) TTL, CMOS Compatible Four-Quadrant Multiplication Single-Supply Operation (+5 V) Low Power Consumption Latch-Up Resistant Available In Die Form APPLICATIONS Voltage Set Points in Automatic Test Equipment Systems Requiring Data Access for Self-Diagnostics Industrial Automation Multichannel Microprocessor-Controlled Systems Digitally Controlled Op Amp Offset Adjustment Process Control Digital Attenuators Quad 8-Bit Multiplying CMOS D, A Converter with Memory DAC8408 A common 8-bit TTL, CMOS compatible input port is used to load data into any of the four DAC data-latches. Control lines DS1, DS2, and A, B determine which DAC will accept data. Data loading is similar to that of a RAMs write cycle. Data can be read back onto the same data bus with control line R, W..
