Overview
The AD5766BCPZ-RL7 is a 16-channel, 16-bit voltage output denseDAC digital-to-analog converter manufactured by Analog Devices Inc. It features integrated output buffers capable of sourcing or sinking up to 20 mA and supports eight software-programmable bipolar output ranges, including ±5 V and −20 V to 0 V. The device incorporates two dither signal input pins for superimposing low-frequency signals and includes a channel monitoring multiplexer. It utilizes a versatile 4-wire serial interface compatible with SPI standards and operates within an industrial temperature range of −40°C to +105°C.
Feature Summary
- 16-channel, 16-bit resolution with integrated output buffers providing ±20 mA current capability
- Eight programmable output voltage ranges from −20 V to +14 V using an external 2.5 V reference
- Two dedicated dither signal input pins (N0, N1) for simplified system design
- Integrated 16-to-1 channel monitoring multiplexer accessible via the MUX_OUT pin
Applications
- Mach Zehnder modulator bias control
- Optical networking systems
- Industrial automation instrumentation
- Data acquisition systems
Procurement Notes
Verify the package type upon ordering, as the AD5766 series is available in both a 4 mm × 4 mm WLCSP and a 40-lead LFCSP. The suffix BCPZ indicates the specific package and temperature grade configuration. Confirm that the required output voltage ranges and dither functionality align with the system specifications before procurement.
Selection Notes
Select the AD5766 over the AD5767 when 16-bit resolution is required, as the AD5767 provides only 12-bit resolution. Ensure the application can accommodate the necessary negative supply voltage (AVSS) for the desired output ranges, such as −20 V to 0 V. Verify that the logic voltage levels (VLOGIC) are compatible with the host microprocessor interface requirements.
Part Context
The AD5766BCPZ-RL7 belongs to the denseDAC family of multi-channel converters designed for high-density applications. It shares architectural similarities with the AD5767 but offers higher precision. The RL7 suffix denotes the reel packaging format used for automated assembly processes.
Replacement Considerations
The AD5767BCPZ-RL7 serves as a lower-resolution alternative within the same family. No other direct cross-model replacements are documented in the provided datasheet.
