AD9083BBCZ-RL7

Overview

The AD9083BBCZ-RL7 is a 16-channel, 125 MHz bandwidth, continuous time sigma-delta analog-to-digital converter manufactured by Analog Devices Inc. It operates with 1.0 V and 1.8 V supplies and supports sample rates up to 2 GSPS. The device features a 16-bit resolution, differential input type, and SPI interface. Key performance metrics include an SNR of 66 dBFS in a 100 MHz bandwidth and 82 dBFS in a 15.625 MHz bandwidth at 2.0 GSPS encoding. Power consumption ranges from 63 mW to 90 mW per channel depending on the operating mode.

Feature Summary

• Integrates programmable single-pole antialiasing filters and termination resistors for simplified design.
• Includes digital processing blocks such as CIC decimation filters, programmable DDCs, and data gating capabilities.
• Supports flexible JESD204B Subclass 1 encoded outputs with lane configurations up to four.
• Features background nonlinearity correction logic and self-cancelling dither within each ADC core.

Applications

• Millimeter wave imaging
• Electronic beam forming and phased arrays
• Multichannel wideband receivers
• Electronic support measures

Procurement Notes

Verify the specific ordering suffix RL7 confirms reel packaging when sourcing this component. Confirm that the BC package variant matches the required footprint for the target PCB layout. Ensure compatibility with the AD9083EBZ evaluation board if initial system validation is planned. Check for any recent manufacturing changes or reliability reports associated with this part number before finalizing procurement.

Selection Notes

Select this component for applications requiring high channel count and low power consumption. Evaluate the trade-off between SNR and power dissipation using the EN_HP setting. Consider the available decimation options and lane configurations to match the receiving logic device's interface requirements. Verify that the 125 MHz full-power bandwidth aligns with the signal spectrum needs.

Part Context

This part belongs to the AD9083 family of multichannel ADCs designed for high-performance data acquisition systems. It utilizes a first-order continuous-time sigma-delta modulator architecture. The device is specified over an industrial temperature range and is housed in a small 100-ball CSP_BGA package to minimize PCB space usage.

Replacement Considerations

The AD9083BBCZ is the tray-packaged equivalent of this reel-delivered part. Both variants share identical electrical specifications and functionality. Verify that the change in packaging does not impact the automated assembly process or storage conditions required for the production line.
