AD5676BCPZ-RL

Overview

The AD5676BCPZ-RL is an octal, 16-bit buffered voltage output digital-to-analog converter (DAC) from Analog Devices. It features a 50 MHz SPI interface and operates on a single 2.7 V to 5.5 V supply. The device provides high relative accuracy with a maximum integral nonlinearity (INL) of ±3 LSB for the B grade. It includes user-selectable gain settings of 1 or 2 via the GAIN pin, allowing full-scale outputs of VREF or 2 × VREF. The part is housed in a 20-lead LFCSP package and supports an operating temperature range from −40°C to +125°C.

Feature Summary

• Octal 16-bit resolution with ±3 LSB maximum INL (B Grade)
• 50 MHz SPI serial interface with readback capability
• User-selectable gain of 1 or 2 via hardware pin or register
• Per-channel power-down mode reducing current consumption to typically 1 µA

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and reel specifications. Confirm that the B grade accuracy meets the design requirements for integral nonlinearity and offset error. Ensure the procurement source provides valid traceability for the component.

Selection Notes

Select this component when eight independent 16-bit voltage outputs are required within a compact footprint. The LFCSP package is suitable for space-constrained designs. Verify that the external reference voltage and logic levels are compatible with the 2.7 V to 5.5 V supply range and 1.62 V to 5.5 V logic interface.

Part Context

This part belongs to the AD5676 nanoDAC+ family, which offers octal 16-bit conversion capabilities. It is distinct from the AD5675 series, which utilizes an I2C interface instead of SPI. The BC suffix indicates the B grade performance level and the LFCSP package style.

Replacement Considerations

The AD5676ARUZ-REEL7 serves as a functional substitute, offering identical electrical specifications but utilizing a TSSOP-20 package instead of the LFCSP-20 form factor.
