AD9116BCPZRL7

Overview

The AD9116BCPZRL7 is a dual, low-power, 12-bit TxDAC digital-to-analog converter operating at sample rates up to 125 MSPS. It features differential current outputs with adjustable full-scale currents ranging from 2 mA to 20 mA and an output common-mode level adjustable from 0 V to 1.2 V. The device integrates two on-chip auxiliary DACs and supports LVCMOS clock inputs. Power consumption is 232 mW at 125 MSPS with a 3.3 V supply, reducing to less than 3 mW in sleep mode. It operates on analog supplies from 1.8 V to 3.3 V and is housed in a 40-lead LFCSP package.

Feature Summary

• Dual-channel architecture with 12-bit resolution and 125 MSPS update rate
• Adjustable output common-mode voltage from 0 V to 1.2 V for flexible interfacing
• Integrated internal reference providing 1.025 V nominal output
• Low power dissipation of 232 mW at 125 MSPS (3.3 V) and <3 mW in sleep mode

Applications

• Wireless infrastructure base stations
• Medical instrumentation and ultrasound transducer excitation
• Portable instrumentation and signal generators

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm that the B grade meets the required temperature range of -40°C to +85°C. Ensure the ordering part number matches the 12-bit resolution variant within the AD9114/9115/9116/9117 family.

Selection Notes

Select this component for applications requiring high linearity and low power in transmit signal paths. Compare against AD9114 (8-bit), AD9115 (10-bit), and AD9117 (14-bit) for pin-compatible upgrades based on resolution needs. Verify interface compatibility with LVCMOS clocks and SPI control requirements.

Part Context

This device belongs to the TxDAC family of dual DACs from Analog Devices. It shares identical pinouts and interfaces with the AD9114, AD9115, and AD9117 models, allowing for design flexibility across different resolution requirements without changing the PCB layout.

Replacement Considerations

Pin-compatible alternatives include the AD9114, AD9115, and AD9117. Selection depends on whether lower resolution or higher precision is acceptable for the specific application constraints.
