AD5725ARSZ-1500RL7

Overview

The AD5725ARSZ-1500RL7 is a quad, 12-bit parallel input voltage output digital-to-analog converter (DAC) from Analog Devices. It features guaranteed monotonicity with a maximum integral nonlinearity (INL) of ±0.5 LSB and differential nonlinearity (DNL) of ±1 LSB. The device supports operation from single +5 V to dual ±15 V supplies, utilizing an iCMOS process for low power consumption. Key performance metrics include a maximum settling time of 10 µs for a 10 V step and simultaneous updating via the LDAC pin. It includes double-buffered inputs, asynchronous CLR functionality, and readback capabilities within a 28-lead SSOP package.

Feature Summary

• Quad 12-bit resolution with ±0.5 LSB max INL and ±1 LSB max DNL
• Parallel interface with double-buffered inputs and simultaneous update capability
• Asynchronous CLR function resets registers to zero scale or mid-scale
• Operates on single +5 V to dual ±15 V supplies with <270 mW power dissipation

Applications

• Industrial automation systems
• Closed-loop servo control and process control
• Automotive test and measurement equipment
• Programmable logic controllers (PLCs)

Procurement Notes

Verify the specific suffix '1500RL7' against official documentation to confirm reel quantity and packaging details. Ensure the B-grade accuracy rating matches design requirements for INL specifications. Confirm supply voltage ranges align with system constraints before integration.

Selection Notes

Select this component when four independent 12-bit channels are required in a single package. The parallel interface suits applications needing high-speed data loading. Consider the ±0.5 LSB INL for precision analog signal generation. Verify that the 28-lead SSOP package fits the PCB layout constraints.

Part Context

This part belongs to the AD5725 family of quad DACs. The 'A' grade indicates ±1 LSB INL, while the 'B' grade (often default unless specified otherwise in ordering guides) offers ±0.5 LSB. The 'RSZ' denotes the RoHS-compliant SSOP package. The '1500RL7' suffix typically indicates a specific tape and reel quantity for manufacturing.

Replacement Considerations

Check for direct pin-compatible substitutes within the AD5725 series, such as the AD5725ARZ-1500RL7 if grade differences are acceptable. Verify electrical parameters like settling time and reference input currents when cross-referencing with other manufacturers' quad DACs.
