AD9117BCPZNRL7

Overview

The AD9117BCPZNRL7 is a dual, low-power, 14-bit TxDAC digital-to-analog converter from Analog Devices. It supports sample rates up to 125 MSPS and operates on a single supply voltage ranging from 1.8 V to 3.3 V. The device features differential current outputs with adjustable common-mode levels between 0 V and 1.2 V. Key performance metrics include an SFDR of 85 dBc at 10 MHz output and a noise spectral density of -163 dBc/Hz at 1 MHz output. Power consumption is approximately 220 mW at 125 MSPS with a 3.3 V supply. It includes two on-chip auxiliary DACs and is housed in a compact 40-lead LFCSP package.

Feature Summary

• Dual-channel architecture with 14-bit resolution and 125 MSPS maximum update rate
• Low power operation: 220 mW at 125 MSPS (3.3 V) and <3 mW in sleep mode
• Adjustable output common-mode level from 0 V to 1.2 V for flexible interfacing
• Integrated internal reference and two auxiliary DACs

Applications

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

Procurement Notes

Verify the specific suffix 'RL7' corresponds to the reel packaging configuration as indicated by distributor listings. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) requirements during storage and handling. Ensure the ordering part number matches the exact pinout and electrical specifications required for the target design.

Selection Notes

Select the AD9117 when 14-bit resolution and high dynamic range are required for transmit signal paths. Compare against AD9114, AD9115, and AD9116 if lower resolution or cost constraints apply, as these devices share the same pinout and interface. Consider the 1.8 V to 3.3 V supply flexibility for portable applications requiring low power dissipation.

Part Context

The AD9117 is part of the TxDAC family, which includes the AD9114, AD9115, and AD9116. These devices are pin-compatible and share identical interfaces and packages, allowing for easy upward or downward selection based on resolution and performance needs. They are optimized for communication system transmit paths.

Replacement Considerations

Pin-compatible alternatives within the same family include AD9114, AD9115, and AD9116. Verify that the resolution and AC performance of the substitute meet the application requirements before replacement.
