- Part Models
- 5
- 1ku List Price
- Starting From $5.20
Part Details
- On-Chip Latches for both DACs
- +12 V to +15 V Operation
- DACs matched to 1%
- Four Quadrant Multiplication
- TTL/CMOS Compatible from +12 V to +15 V
- Latch Free (Protection Schottkys not Required)
The AD7628 is a monolithic dual 8-bit digital/analog converter featuring excellent DAC-to-DAC matching. It is available in small 0.3" wide 20-pin DIPs 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 AD7628'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 6502, 6809, 8085, Z80.
The device operates from a +12 V to +15 V power supply and is TTL-compatible over this range. Power dissipation is a low 20 mW.
Both DACs offer excellent four quadrant multiplication characteristics with a separate reference input and feedback resistor for each DAC.
APPLICATIONS
- Disk Drives
- Programmable Filters
- X-Y Graphics

Tools & Simulations
Precision DAC Error Budget Tool
The Precision DAC Error Budget Tool is a web application that calculates the DC Accuracy of precision DAC signal chains. It shows how the static errors accumulate throughout your signal chain to quickly evaluate the design tradeoffs. Calculations include the DC errors introduced by Voltage References, Operation Amplifiers and Precision DACs.
