AD5673RBCPZ-2

Overview

The AD5673RBCPZ-2 is a 16-channel, 12-bit buffered voltage output digital-to-analog converter (DAC) from Analog Devices. It features an internal 2.5 V reference with a typical temperature coefficient of 2 ppm/°C and operates on a single 2.7 V to 5.5 V supply. The device uses a 400 kHz I²C-compatible serial interface and includes a user-selectable gain pin for 2.5 V or 5 V full-scale outputs. Packaged in a 28-lead, 4 mm × 4 mm LFCSP, it guarantees monotonic operation without missing codes and incorporates a power-on reset circuit for safe initialization.

Feature Summary

• 16 channels with 12-bit resolution and ±1 LSB maximum INL
• Internal 2.5 V reference with 2 ppm/°C typical drift
• 400 kHz I²C serial interface with 1.8 V logic compatibility
• Power-down mode reduces current consumption to 2 µA typical

Applications

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

Procurement Notes

Verify the specific suffix '-2' against official documentation to confirm the power-up state configuration. Ensure the ordering part number matches the required initial output voltage level before procurement.

Selection Notes

Select this model when high channel density is required in a compact footprint. Verify that the 12-bit resolution meets system accuracy requirements and that the I²C interface aligns with the host controller capabilities.

Part Context

This component belongs to the nanoDAC+ family, designed for applications requiring multiple analog outputs in space-constrained environments. It shares architectural similarities with other devices in the series but is distinguished by its 16-channel count and I²C connectivity.

Replacement Considerations
