AD5673RBCPZ-1

Overview

The AD5673RBCPZ-1 is a low-power, 16-channel, 12-bit buffered voltage output digital-to-analog converter (DAC) from Analog Devices. It features an internal 2.5 V voltage reference with a typical temperature coefficient of 2 ppm/°C and a user-selectable gain pin for full-scale outputs of 2.5 V or 5 V. The device operates on a single 2.7 V to 5.5 V supply and includes a power-on reset circuit ensuring zero-scale or midscale power-up. It utilizes a 400 kHz I2C-compatible serial interface and is housed in a 28-lead, 4 mm × 4 mm LFCSP package.

Feature Summary

• 16 channels with 12-bit resolution and ±1 LSB maximum INL
• Internal 2.5 V reference with 2 ppm/°C typical drift
• User-selectable gain (×1 or ×2) via GAIN pin
• 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 '-1' against the manufacturer's ordering guide to confirm the exact power-up state configuration (zero scale vs. midscale). Ensure the required packaging format (e.g., reel or tube) matches the intended manufacturing process, as availability varies by variant.

Selection Notes

Select this model when high channel density is required within a compact 4 mm × 4 mm footprint. Choose the -1 suffix if the application demands a specific power-up state other than the default. Verify that the I2C address pins (A0, A1) can accommodate the system's addressing requirements.

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 the AD5677R but offers lower resolution (12-bit vs. 16-bit), providing a cost-effective solution for general-purpose multi-channel control.

Replacement Considerations

The AD5677RBCPZ-1 serves as a higher-resolution alternative within the same package. For SPI-based designs, consider the AD5674R or AD5679R series. Cross-model substitution requires verification of interface compatibility and pin mapping.
