Digital To Analog Converters datasheet and documents for AD5381BST-3
Digital To Analog Converters Overview
The AD5381BST-3 is a single-supply, 40-channel, 12-bit denseDAC in a 100-lead LQFP package. It features rail-to-rail output amplifiers and an on-chip programmable reference (default 1.25 V). The device supports parallel, SPI/QSPI/MICROWIRE/DSP-compatible serial, and I2C interfaces. Key specifications include ±1 LSB INL/DNL, 3 µs typical settling time, and power-down modes. Operating ranges are AVDD 2.7 V to 3.6 V and DVDD 2.7 V to 5.5 V.
Digital To Analog Converters Feature Summary
- 40 channels with 12-bit resolution and rail-to-rail buffered outputs
- On-chip 1.25 V/2.5 V programmable reference with 10 ppm/°C stability
- Triple interface support: Parallel, Serial (SPI/I2C), and FIFO capability
- Integrated channel monitor, simultaneous update via LDAC, and thermal monitors
Digital To Analog Converters Applications
- Variable optical attenuators (VOAs)
- Level setting for automated test equipment (ATE)
- Optical micro-electro-mechanical systems (MEMs) control
- General instrumentation and control systems
Digital To Analog Converters Procurement Notes
Verify the suffix 'BST-3' confirms the industrial temperature range (-40°C to +85°C) and 3 V analog supply specification. Confirm the 100-lead LQFP package dimensions match the design footprint. Ensure external decoupling capacitors meet the datasheet requirements for AVDD and DVDD pins.
Digital To Analog Converters Selection Notes
Select this model when 40 independent voltage outputs are required in a compact form factor. The AD5381-3 variant is optimized for 3 V analog supplies; use the AD5381-5 if 5 V operation is needed. Consider the integrated monitor function for system diagnostics and the boost mode for applications requiring faster slew rates.
Digital To Analog Converters Part Context
The AD5381 belongs to Analog Devices' denseDAC family, designed for high-density multi-channel applications. It integrates special function registers for gain/offset calibration and toggle modes. The BST suffix indicates the commercial/industrial temperature grade within the broader AD5381 product line.
Digital To Analog Converters Replacement Considerations
Direct pin-compatible replacements within the same series include the AD5381-5 for 5 V analog supply applications. Verify interface compatibility and register mapping when substituting between different density DACs or older generations.
