AD5669RBCBZ-1-R5

Overview

The AD5669RBCBZ-1-R5 is an octal, 16-bit buffered voltage-output digital-to-analog converter (DAC) from Analog Devices. It features a 2.6 mm × 2.6 mm 16-ball WLCSP package and operates on a single 2.7 V to 5.5 V supply. The device includes an on-chip 1.25 V reference with a temperature coefficient of 5 ppm/°C, yielding a full-scale output range of 2.5 V. Key electrical parameters include a settling time of 2.5 µs, differential nonlinearity of ±1 LSB, and power-down current as low as 200 nA at 3 V. It supports I2C interfaces in standard (100 kHz) and fast (400 kHz) modes.

Feature Summary

• Octal architecture with 16-bit resolution and rail-to-rail buffered voltage outputs.
• Integrated 1.25 V reference with 5 ppm/°C temperature stability for a 2.5 V full-scale range.
• Ultra-low power consumption with 200 nA power-down mode at 3 V.
• Hardware LDAC and CLR functions alongside software-selectable power-down states.

Applications

• Process control systems
• Data acquisition systems
• Portable battery-powered instruments
• Programmable voltage and current sources

Procurement Notes

Verify the specific suffix -1-R5 against the manufacturer's ordering guide to confirm the internal reference selection (1.25 V) and packaging type (WLCSP). Ensure compatibility with the required operating voltage range of 2.7 V to 5.5 V. Confirm that the I2C address configuration via the A0 pin meets system requirements.

Selection Notes

Select this component when eight independent 16-bit channels are required in a minimal footprint. The internal 1.25 V reference limits the maximum output swing to 2.5 V; use the -2 or -3 variants if a 5 V full-scale range is needed. Verify that the load capacitance does not exceed 2 nF without external resistance to maintain stability.

Part Context

This part belongs to the denseDAC family, designed for high channel density in space-constrained applications. It shares functional similarities with the AD5629R but offers higher 16-bit resolution. The -1 suffix specifically denotes the 1.25 V internal reference option, distinguishing it from other variants with different reference voltages or power-on reset behaviors.
