AD9115BCPZRL7

Overview

The AD9115BCPZRL7 is a dual, low-power, 10-bit digital-to-analog converter (DAC) from Analog Devices. Operating at sample rates up to 125 MSPS, it features two main DAC channels and two auxiliary DACs within a 40-lead LFCSP package. The device supports analog supply voltages from 1.8 V to 3.3 V and digital I/O levels of 1.8 V or 3.3 V. Key electrical specifications include a typical Spurious Free Dynamic Range (SFDR) of 85 dBc at 10 MHz output with a 125 MSPS clock rate. Power consumption is approximately 220 mW at 125 MSPS with a 3.3 V analog supply.

Feature Summary

• Dual 10-bit DAC architecture with two on-chip auxiliary DACs
• Maximum conversion rate of 125 MSPS with LVCMOS clock input
• Low power dissipation: 220 mW at 125 MSPS (3.3 V AVDD)
• Adjustable output common-mode voltage from 0 V to 1.2 V

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 reel packaging when sourcing. Confirm that the BC grade meets the required operating temperature range of -40°C to +85°C. Ensure the ordering part number matches the exact resolution and package type required for the design.

Selection Notes

Select the AD9115BCPZRL7 over the AD9114 or AD9116 based on the need for 10-bit resolution. This component shares pinouts with the 8-bit, 12-bit, and 14-bit variants in the family, allowing for flexible component selection based on performance and cost requirements without changing the PCB layout.

Part Context

This component belongs to the TxDAC family of dual digital-to-analog converters. It is designed for transmit signal paths in communication systems. The device is pin-compatible with the AD9114, AD9116, and AD9117, sharing the same interface, package, and pinout configuration.

Replacement Considerations

Pin-compatible alternatives within the same series include the AD9114BCPZRL7 (8-bit), AD9116BCPZRL7 (12-bit), and AD9117BCPZRL7 (14-bit). These devices share identical packages and interfaces, facilitating direct substitution based on resolution needs.
