• TTL/CMOS-Compatible
• No User Trims
• Extended Temperature Range Operation
• Single Supply Operation Possible
Applications:
• Process Control
• Automatic Test Equipment
• Automatic Calibration of Large System Parameters,
• e.g., Gain/Offset
Product Highlights:
1. DAC-to-DAC Matching
Since all four DACs are fabricated on the same chip at the same time, precise matching and tracking between the DACs is inherent.
2. Single-Supply Operation
The voltage mode configuration of the DACs allows the AD7226 to be operated from a single power supply rail.
3. Microprocessor Compatibility
The AD7226 has a common 8-bit data bus with individual DAC latches, providing a versatile control architecture for simple interface to microprocessors. All latch enable signals are level triggered.
4. Small Size
Combining four DACs and four op amps plus interface logic into a 20-pin package allows a dramatic reduction in board space requirements and offers increased reliability in systems using multiple converters. Its pinout is aimed at optimizing board layout with all the analog inputs and outputs at one end of the package and all the digital inputs at the other.
