AD5675ACPZ-RL

Overview

The AD5675ACPZ-RL is an octal, 16-bit buffered voltage output digital-to-analog converter (DAC) from Analog Devices. It features a user-selectable gain of 1 or 2 via the GAIN pin, allowing full-scale outputs of VREF or 2 × VREF. The device operates on a single 2.7 V to 5.5 V supply and includes a power-on reset circuit with RSTSEL for zero or midscale initialization. It utilizes a versatile 2-wire I2C-compatible serial interface with clock rates up to 400 kHz and supports 1.8 V logic levels. The component is housed in a 20-lead LFCSP package.

Feature Summary

• Octal architecture with eight independent 16-bit DAC channels
• High relative accuracy with maximum INL of ±3 LSB at 16 bits
• User-selectable gain configuration (×1 or ×2) via hardware pin
• Integrated power-on reset ensuring defined startup state

Applications

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

Procurement Notes

Verify the specific suffix 'ACPZ-RL' against the manufacturer's current ordering guide to confirm the package type (LFCSP) and reel packaging quantity. Ensure the selected grade (A or B) matches the required linearity specifications, as performance parameters vary between grades.

Selection Notes

Select this component when multiple isolated analog outputs are required from a single controller. Verify that the external reference voltage falls within the specified input range for the chosen gain setting. Confirm that the load capacitance does not exceed stability limits without additional buffering.

Part Context

This part belongs to the nanoDAC+ family, designed for low-power applications requiring high precision. It serves as a multi-channel solution for systems needing simultaneous analog updates via a standard I2C interface, reducing board space compared to discrete single-channel converters.

Replacement Considerations

The AD5676BCPZ-RL offers identical pinout and functionality but uses an SPI interface instead of I2C. Substitution requires modifying the microcontroller's communication protocol.
