AD9116BCPZ

Overview

The AD9116BCPZ is a dual-channel, 12-bit low-power digital-to-analog converter (DAC) from Analog Devices. It operates at sample rates up to 125 MSPS and features differential current outputs with adjustable full-scale currents ranging from 2 mA to 20 mA. The device supports flexible power supply voltages between 1.7 V and 3.5 V for analog and clock supplies, and 1.7 V to 3.5 V for digital I/O. Key performance metrics include a post-calibration DNL of ±0.2 LSB and INL of ±0.42 LSB. It integrates two auxiliary DACs, an internal reference, and an SPI interface for configuration.

Feature Summary

• Dual-channel architecture with 12-bit resolution and 125 MSPS maximum update rate
• Low power consumption: 232 mW at 125 MSPS with 3.3 V supplies; sleep mode under 3 mW
• Adjustable output common-mode voltage from 0 V to 1.2 V for easy interfacing
• Integrated internal reference and two auxiliary DACs for system calibration

Applications

• Wireless infrastructure base stations
• Picocell and femtocell systems
• Medical instrumentation
• Ultrasound transducer excitation
• Portable signal generators

Procurement Notes

Verify the specific suffix 'BCPZ' corresponds to the RoHS-compliant 40-lead LFCSP package variant. Confirm that the ordering code matches the 12-bit resolution version within the AD9114/9115/9116/9117 family. Ensure compatibility with the required supply voltage ranges and thermal management specifications for the target application environment.

Selection Notes

Select the AD9116BCPZ when 12-bit resolution is required alongside low power dissipation in portable or battery-operated designs. Compare against AD9114 (8-bit), AD9115 (10-bit), and AD9117 (14-bit) for pin-compatible upgrades based on dynamic performance needs. Ensure the design accommodates the LVCMOS clock input and SPI control interface requirements.

Part Context

The AD9116BCPZ belongs to the TxDAC family of dual low-power DACs. It shares identical pinouts and interfaces with the AD9114, AD9115, and AD9117, allowing for straightforward migration between resolutions without redesigning the PCB layout. This pin compatibility simplifies inventory management and design flexibility across different product tiers.

Replacement Considerations

Pin-compatible alternatives within the same series include the AD9114BCPZ (8-bit), AD9115BCPZ (10-bit), and AD9117BCPZN (14-bit). Verify that the substitute part meets the specific resolution and dynamic performance requirements of the original design.
