AD7225CRSZ-RL

Overview

The AD7225CRSZ-RL is an LC2MOS quad 8-bit voltage-output digital-to-analog converter (DAC) in a 24-lead SSOP package. It integrates four DACs with output buffer amplifiers and double-buffered interface logic on a single chip. Each channel features a separate reference input, allowing independent configuration. The device supports simultaneous update of all outputs via the LDAC signal and operates with single or dual supplies. Static performance includes ±1 LSB total unadjusted error for L/C versions, with a settling time of 4 µs max.

Feature Summary

• Quad 8-bit architecture with integrated output buffer amplifiers
• Separate reference inputs (VREFA-D) for each DAC channel
• Double-buffered interface enabling simultaneous multi-channel updates
• TTL/CMOS compatible digital inputs with microprocessor interface

Applications

• Programmable gain amplifiers
• Digital potentiometer replacement
• Programmable filters
• Waveform generation

Procurement Notes

Verify the 'C' suffix indicates the commercial temperature range (-40°C to +85°C). Confirm the '-RL' suffix corresponds to reel packaging as per the manufacturer's ordering guide. Ensure the specific lot date code meets project requirements before finalizing procurement.

Selection Notes

Select this component when four independent 8-bit DACs are required in a compact surface-mount package. The L/C version offers improved accuracy (±1 LSB TUE) compared to K/B versions. Ensure the application can provide the necessary VDD-VREF overhead of at least 4V for specified performance.

Part Context

This part belongs to the AD7225 family of quad DACs. The CRSZ designation specifies the 24-lead SSOP plastic package variant. Other package options include PDIP, SOIC, CERDIP, and PLCC. The device utilizes LC2MOS technology for high-speed digital and precision analog integration.

Replacement Considerations

Direct pin-compatible replacements within the same package include other AD7225 variants such as AD7225ARZ or AD7225LPZ, provided the temperature grade and accuracy class (L/C vs K/B) meet the design specifications.
