Overview
The AD5677RBCPZ-1 is a 16-channel, 16-bit buffered voltage output digital-to-analog converter (DAC) from Analog Devices. It integrates a 2.5 V internal voltage reference with a typical temperature coefficient of 2 ppm/°C and features an I2C-compatible serial interface. The device operates on a single 2.7 V to 5.5 V supply and includes a user-selectable gain pin for full-scale outputs of 2.5 V or 5 V. Key performance metrics include a maximum integral nonlinearity (INL) of ±4 LSB, a settling time of 6 µs, and a signal-to-noise ratio (SNR) of 90 dB. It is housed in a 28-lead, 4 mm × 4 mm LFCSP package.
Feature Summary
- 16 channels with 16-bit resolution and ±4 LSB maximum INL
- Integrated 2.5 V reference with 2 ppm/°C temperature coefficient
- I2C interface with 1.8 V logic compatibility and 400 kHz speed
- User-selectable gain (×1 or ×2) via GAIN pin
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 '-1' against the manufacturer's ordering guide to confirm the default power-up state (zero scale vs. midscale). Ensure the required package type (LFCSP-28) and interface protocol (I2C) match the system design constraints before procurement.
Selection Notes
Select this model over the AD5673R variant when 16-bit resolution and higher relative accuracy (±4 LSB INL) are required. Confirm that the I2C address configuration via A0/A1 pins fits the bus topology. Verify that the 40 mA short-circuit current capability meets load protection requirements.
Part Context
This component belongs to the nanoDAC+ family, designed for high channel density in compact packages. It shares the same physical footprint and interface as the 12-bit AD5673R, allowing for potential pin-compatible upgrades where higher resolution is needed without redesigning the PCB layout.
Replacement Considerations
The AD5673RBCPZ-1 is a pin-compatible alternative offering 12-bit resolution. Other family members like the AD5679R use SPI interfaces and are not direct replacements without interface modification.
