AD5593RBRUZ

Overview

The AD5593RBRUZ is an 8-channel, 12-bit configurable analog-to-digital converter (ADC) and digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It integrates a 2.5 V on-chip reference with a 20 ppm/°C temperature coefficient. The device features eight independently configurable I/O pins that function as DAC outputs, ADC inputs, or general-purpose digital I/O. Communication is handled via an I²C interface. Electrical specifications include a supply voltage range of 2.7 V to 5.5 V, an operating temperature range of −40°C to +105°C, and a 16-lead TSSOP package.

Feature Summary

• Eight configurable I/O channels supporting 12-bit DACs, 12-bit ADCs, and GPIO functions.
• Integrated 2.5 V precision reference with 20 ppm/°C temperature coefficient.
• I²C serial interface for control and data transfer.
• Built-in temperature sensor providing die temperature indication.

Applications

• Control and monitoring systems
• General-purpose analog and digital I/O expansion

Procurement Notes

Verify the specific ordering suffix BRUZ corresponds to the 16-lead TSSOP package configuration. Confirm the revision level matches the required design specifications. Ensure compatibility with the target system's I²C bus voltage levels and timing requirements before finalizing procurement.

Selection Notes

Select this component when a single chip must handle mixed-signal tasks including analog output generation, analog input acquisition, and digital switching. The internal 2.5 V reference simplifies design but requires checking if external references are needed for higher precision. Verify that the 12-bit resolution and I²C speed meet the application's latency and accuracy constraints.

Part Context

This part belongs to the AD5593R family of mixed-signal converters. It serves as a hardware-reconfigurable node for embedded systems, reducing bill-of-materials complexity compared to using separate ADC, DAC, and GPIO expander chips. The BRUZ suffix specifically denotes the surface-mount TSSOP-16 package variant.

Replacement Considerations

The AD5592R is a pin-compatible alternative offering SPI interface functionality instead of I²C. When substituting, verify that the host microcontroller supports the SPI protocol and adjust the software driver accordingly.
