AD5593RBCPZ-RL7

Overview

The AD5593RBCPZ-RL7 is an 8-channel, 12-bit configurable analog-to-digital converter and digital-to-analog converter manufactured by Analog Devices Inc. It features eight independently configurable I/O pins that can be set as DAC outputs, ADC inputs, or general-purpose digital I/O. The device includes an integrated 2.5 V reference with a temperature coefficient of 20 ppm/°C and an on-chip temperature sensor. It operates on a supply voltage between 2.7 V and 5.5 V and communicates via an I2C interface. Key electrical parameters include a maximum INL of ±2 LSB for the ADC and ±1 LSB for the DAC, with a typical settling time of 6 µs.

Feature Summary

• Eight configurable I/O channels supporting simultaneous 12-bit DAC, ADC, and GPIO operations
• Integrated 2.5 V reference (20 ppm/°C) and temperature indicator sensor
• I2C serial interface compatible with standard and fast modes
• Operates over an extended temperature range from -40°C to +105°C

Applications

• Control and monitoring systems
• General-purpose analog and digital I/O expansion
• Industrial process control interfaces

Procurement Notes

Verify the LFCSP-16 package configuration and reel packaging details against the specific manufacturing revision. Confirm I2C address settings via the A0 pin logic level requirements for system integration. Ensure power supply decoupling meets the datasheet recommendations for specified performance.

Selection Notes

Select this component when high channel density and mixed-signal flexibility are required in a single package. Compare with the AD5592R if SPI communication is preferred over I2C. Verify that the internal 2.5 V reference meets accuracy requirements or plan for external reference implementation if higher precision is needed.

Part Context

This part belongs to the AD5593R family of configurable data acquisition converters. It serves as the I2C-interface variant within the series, distinct from the SPI-based AD5592R. The BC suffix indicates the LFCSP package type, while RL7 denotes the tape and reel shipping format.

Replacement Considerations

The AD5592RBCPZ-RL7 is functionally equivalent but utilizes an SPI interface instead of I2C. Direct pin-for-pin replacement requires significant firmware and hardware interface modifications.
