AD5592RBCPZ-RL7

Overview

The AD5592RBCPZ-RL7 is an 8-channel, 12-bit configurable ADC/DAC with an integrated SPI interface and on-chip reference. It features eight I/O pins independently configurable as DAC outputs, ADC inputs, or GPIOs. The device operates on a 2.7 V to 5.5 V supply and supports a total ADC throughput of 400 kSPS. It includes a 2.5 V internal reference and temperature sensor. Packaged in a 16-lead LFCSP (3 mm × 3 mm), it functions within a -40°C to +105°C ambient temperature range.

Feature Summary

• Eight configurable I/O channels supporting 12-bit DAC, ADC, and GPIO operations
• Integrated 2.5 V reference with 20 ppm/°C temperature coefficient
• SPI serial interface with 400 kSPS total ADC throughput rate
• On-chip temperature indicator providing die temperature readings

Applications

• Control and monitoring systems
• General-purpose analog and digital input/output interfaces
• Process control data acquisition

Procurement Notes

Verify the package type matches the required PCB footprint, specifically the 16-lead LFCSP configuration. Confirm that the system logic levels are compatible with the standard VDD voltage range, as this variant lacks the dedicated 1.8 V logic pin found in the AD5592R-1 series. Ensure the design accounts for the specified operating temperature limits.

Selection Notes

Select this component when an SPI interface is preferred over I2C. Choose the AD5592RBCPZ-RL7 for applications requiring the compact 3 mm × 3 mm LFCSP package. If 1.8 V logic compatibility is necessary, consider the AD5592R-1 derivative instead. Verify that the 400 kSPS aggregate sampling rate meets the multi-channel data acquisition requirements.

Part Context

This part belongs to the AD5592R family of mixed-signal converters. It serves as the SPI-interface counterpart to the AD5593R, which utilizes an I2C interface. The BC suffix indicates the specific LFCSP package variant, while the RL7 suffix denotes the reel packaging format used for surface-mount assembly.

Replacement Considerations

The AD5592RBRUZ offers the same functionality in a TSSOP-16 package. For I2C connectivity, the AD5593RBCPZ-RL7 provides equivalent channel counts and resolution. The AD5592RBCPZ-1-RL7 is functionally identical but adds support for 1.8 V logic levels via a separate VLOGIC pin.
