AD9117BCPZRL7

Overview

The AD9117BCPZRL7 is a dual-channel, 14-bit digital-to-analog converter (DAC) from Analog Devices. It operates at sampling rates up to 125 MSPS with low power consumption of 232 mW at maximum rate and under 3 mW in sleep mode. The device features differential current outputs adjustable from 2 mA to 20 mA and includes two on-chip auxiliary DACs. It supports flexible supply voltages ranging from 1.8 V to 3.3 V and offers an output common-mode level adjustable between 0 V and 1.2 V. Packaged in a 40-lead LFCSP, it provides high spurious-free dynamic range (SFDR) of 86 dBc at 1 MHz output.

• Adjustable full-scale output current from 2 mA to 20 mA
• Integrated internal reference and two auxiliary DACs

Applications

• Wireless infrastructure base stations
• Medical instrumentation
• Ultrasound transducer excitation
• Signal generators and arbitrary waveform generators

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm RoHS compliance status for the exact batch. Ensure the ordering part number matches the required package type and temperature grade before finalizing procurement.

Selection Notes

Select this component for applications requiring low power dissipation and high linearity in transmit signal paths. Compare against AD9114/AD9115/AD9116 if different resolutions or cost constraints apply, as they share pinouts. Verify interface compatibility with LVCMOS clock inputs and SPI control requirements.

Part Context

Part of the TxDAC family optimized for communication system transmit paths. Shares interface and pinout with AD9114, AD9115, and AD9116 for easy migration based on performance needs.

Replacement Considerations

Pin-compatible alternatives include AD9114, AD9115, and AD9116 within the same series. Verify resolution and power specifications match application requirements when substituting.
