- Part Models
- 21
- 1ku List Price
- Starting From $10.41
Part Details
- On-Chip Latches for Both DACs
- +5 V to +15 V Operation
- DACs Matched to 1%
- Four Quadrant Multiplication
- TTL/CMOS Compatible
- Latch Free (Protection Schottkys not Required)
The AD7528 is a monolithic dual 8-bit digital/analog converter featuring excellent DAC-to-DAC matching. It is available in skinny 0.3" wide 20-pin DIP's and in 20-terminal surface mount packages.
Separate on-chip latches are provided for each DAC to allow easy microprocessor interface.
Data is transferred into either of the two DAC data latches via a common 8-bit TTL/CMOS compatible input port. Control input DAC A/DAC B determines which DAC is to be loaded. The AD7528's load cycle is similar to the write cycle of a random access memory and the device is bus compatible with most 8-bit microprocessors, including 6800, 8080, 8085, Z80.
The device operates from a +5V to +15V power supply, dissipating only 20mW of power.
Both DAC's offer excellent four quadrant multiplication characteristics with a separate reference input and feedback resistor for each DAC.
PRODUCT HIGHLIGHTS
- DAC-to-DAC matching: since both of the AD7528 DACs are fabricated at the same time on the same chip, precise matching and tracking between DAC A and DAC B is inherent. The AD7528’s matched CMOS DACs make a whole new range of applications circuits possible, particularly in the audio, graphics and process control areas.
- Small package size: combining the inputs to the on-chip DAC latches into a common data bus and adding a DAC A/DAC B select line has allowed the AD7528 to be packaged in either a small 20-lead DIP, SOIC or PLCC.
