AD5672RBCPZ-RL

Overview

The AD5672RBCPZ-RL is an octal, 12-bit buffered voltage output digital-to-analog converter (DAC) from Analog Devices. It features a high-performance architecture with a maximum integral nonlinearity (INL) of ±1 LSB and a gain error of ±0.06% FSR. The device includes a low-drift 2.5 V internal reference with a typical temperature coefficient of 2 ppm/°C. Operating on a single supply from 2.7 V to 5.5 V, it supports a user-selectable gain of 1 or 2 via the GAIN pin, providing full-scale outputs of 2.5 V or 5 V respectively. The unit utilizes a 50 MHz SPI interface with readback capability and operates within a temperature range of -40°C to +125°C.

Feature Summary

• Octal 12-bit resolution with ±1 LSB maximum INL and ±0.06% FSR gain error
• Integrated 2.5 V reference with 2 ppm/°C typical drift
• User-selectable gain (1x or 2x) for 2.5 V or 5 V full-scale output
• 50 MHz SPI interface with daisy-chain and readback support

Applications

• Optical transceivers
• Base station power amplifiers
• Process control PLC input/output cards
• Industrial automation systems
• Data acquisition systems

Procurement Notes

Verify that the ordering suffix RL corresponds to the reel packaging format required for the production line. Confirm that the BCPZ designation matches the LFCSP package type and RoHS compliance status specified in the manufacturer's documentation. Ensure compatibility with the intended logic voltage levels before procurement.

Selection Notes

Select this component when eight independent 12-bit channels are required in a compact form factor. The internal 2.5 V reference simplifies design by reducing external component count. Verify that the 2.7 V to 5.5 V supply range aligns with the system power architecture. Consider the 50 MHz SPI speed if high throughput is necessary for the application.

Part Context

This part belongs to the AD5672R/AD5676R nanoDAC+ family, which provides high channel density and accuracy. The AD5672R specifically offers 12-bit resolution, whereas the AD5676R variant provides 16-bit resolution. Both share similar interfaces and pinouts but differ in performance specifications such as INL and settling time.

Replacement Considerations

The AD5676R serves as a higher-resolution alternative within the same family. For I2C interface requirements, the AD5671R is the corresponding 12-bit option. External reference versions like the AD5676 may be considered if an internal reference is not desired.
