Overview
The AD5664RBRMZ-3 is a quad, 16-bit buffered voltage-output digital-to-analog converter (DAC) from Analog Devices. It operates on a single 2.7 V to 5.5 V supply and features an on-chip 1.25 V reference with 5 ppm/°C temperature coefficient, yielding a 2.5 V full-scale output range. The device supports serial interfaces up to 50 MHz, including SPI and QSPI. Key electrical parameters include a settling time of 4 µs, ±1 LSB differential nonlinearity, and power consumption of 1.32 mW at 3 V. It is housed in a 10-lead MSOP package.
Feature Summary
- Quad 16-bit resolution with rail-to-rail buffered voltage outputs
- Integrated 1.25 V precision reference (5 ppm/°C) or external reference input
- Versatile 3-wire serial interface compatible with standard DSP protocols up to 50 MHz
- Per-channel power-down modes reducing current to 480 nA at 5 V
Applications
- Process control systems
- Data acquisition systems
- Portable battery-powered instruments
- Programmable voltage and current sources
Procurement Notes
Verify the specific suffix '-3' confirms the internal 1.25 V reference configuration. Confirm the 'B' grade indicates the specified accuracy range (-40°C to +105°C). Ensure the 'MSOP' package designation matches the required footprint for PCB layout.
Selection Notes
Select this component when four independent 16-bit channels are required in a compact form factor. The internal 1.25 V reference limits the maximum output swing to 2.5 V; use the -5 variant for 5 V swings. Verify that the 50 MHz serial clock speed meets the system timing requirements.
Part Context
This part belongs to the nanoDAC family, designed for low-power applications. It shares pin compatibility with the AD5624R (12-bit) and AD5644R (14-bit) variants, allowing for resolution upgrades without changing the PCB layout.
Replacement Considerations
The AD5664RBRMZ-5 serves as a direct replacement if a 5 V full-scale output range is required, utilizing the same 2.5 V internal reference. Other quad DACs may require level shifting or different pin configurations.
