AD5593RBCBZ-RL7

Overview

The AD5593RBCBZ-RL7 is an 8-channel, 12-bit configurable ADC/DAC with an I2C interface and on-chip reference. It integrates eight input/output pins independently configurable as DAC outputs, ADC inputs, or general-purpose digital I/O. The device features a 2.5 V internal reference (20 ppm/°C) and an integrated temperature sensor. Operating from 2.7 V to 5.5 V, it supports output ranges of 0 V to VREF or 0 V to 2 × VREF. Key electrical parameters include 12-bit resolution, ±2 LSB INL for ADC, ±1 LSB DNL for both ADC and DAC, and a typical DAC settling time of 6 µs.

Feature Summary

• Eight configurable I/O channels supporting simultaneous 12-bit DAC outputs, 12-bit ADC inputs, and GPIO functions.
• Integrated 2.5 V precision reference with 20 ppm/°C temperature coefficient and built-in temperature indicator.
• I2C serial interface compatible with standard and fast modes, operating within 2.7 V to 5.5 V supply range.
• 16-ball WLCSP package (CB-16-3) designed for space-constrained surface-mount applications.

Applications

• Control and monitoring systems requiring mixed analog/digital signal processing.
• General-purpose analog and digital I/O expansion in embedded controllers.
• Industrial sensor interfaces utilizing programmable excitation and acquisition.

Procurement Notes

Verify the specific suffix RL7 corresponds to reel packaging when sourcing. Confirm the CB package variant matches the target PCB footprint. Ensure voltage levels align with the 2.7 V to 5.5 V operational range. Check for moisture sensitivity handling requirements prior to assembly.

Selection Notes

Select this model for designs requiring high channel density in a minimal footprint. The WLCSP package offers a smaller area compared to TSSOP or LFCSP variants. Verify that the system logic voltage supports the required I2C communication levels. Consider thermal dissipation limits inherent to the small ball grid array structure.

Part Context

This component belongs to the AD5593R family, which provides 12-bit configurable data acquisition capabilities. It serves as an alternative to discrete ADC/DAC combinations, reducing bill of materials complexity. The BC designation indicates the WLCSP package type, distinguishing it from the CP (LFCSP) or RU (TSSOP) versions.

Replacement Considerations

The AD5592R series offers equivalent functionality but utilizes an SPI interface instead of I2C. Direct pin-to-pin replacement requires adapting the microcontroller's serial communication protocol. Package differences between WLCSP and other form factors necessitate custom PCB layout adjustments.
