AD660BNZ

Overview

The AD660BNZ is a monolithic 16-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It features a single channel with voltage output and supports Microwire or SPI serial interfaces. The device operates within an analog supply range of 13.5 V to 16.5 V and a digital supply of 4.5 V to 5.5 V. Key electrical parameters include a settling time of 8 µs, differential nonlinearity (DNL) of ±1 LSB, and integral nonlinearity (INL) of ±1 LSB. It consumes 12 mA of operating current with a power dissipation of 1 W. The component is housed in a 24-lead PDIP package and functions across a temperature range of -40°C to +85°C.

Feature Summary

• 16-bit resolution with high accuracy specifications including ±1 LSB DNL and INL
• Serial interface compatibility with Microwire and SPI protocols
• Integrated internal reference and on-chip gain amplifier
• Single-supply operation capability for simplified system design

Applications

• High-resolution data acquisition systems
• Precision industrial process control instrumentation
• Medical equipment requiring accurate signal generation
• Test and measurement instruments

Procurement Notes

Verify the specific suffix 'BNZ' to confirm the lead-free RoHS-compliant variant and commercial temperature grade (-40°C to +85°C). Ensure the ordering code matches the 24-lead PDIP package configuration. Cross-reference the manufacturer's latest datasheet for any updates to mechanical dimensions or pin assignments before finalizing procurement.

Selection Notes

Select this component when a 16-bit resolution DAC with integrated reference and amplifier is required. Verify that the system can accommodate the separate analog (13.5–16.5 V) and digital (4.5–5.5 V) supply rails. Confirm that the serial interface timing aligns with the host controller's Microwire or SPI capabilities. Consider the 8 µs settling time against the required update rate of the application.

Part Context

The AD660BNZ belongs to the AD660 series of monolithic DACs from Analog Devices. This series is designed to provide complete conversion solutions by integrating the DAC core, reference, and amplifier into a single chip. The BNZ suffix indicates a specific packaging and environmental compliance version within the broader AD660 product family.

Replacement Considerations

Consult Analog Devices documentation for direct replacements or pin-compatible alternatives within the AD660 series. Verify functional equivalence regarding supply voltages, interface protocols, and linearity specifications before substituting.
