AD9214BRS-RL105

Overview

The AD9214BRS-RL105 is a 10-bit monolithic sampling analog-to-digital converter (ADC) from Analog Devices Inc. It operates at a maximum conversion rate of 105 MSPS with an analog input bandwidth of 300 MHz. The device features an on-chip track-and-hold circuit and supports either 1 V p-p or 2 V p-p differential analog input ranges. It requires a single 3.3 V supply (2.7 V to 3.6 V) for analog operation and a separate digital output driver supply (DrVDD). Power consumption is 285 mW at 105 MSPS, reducing to 30 mW in power-down mode. The component is housed in a 28-lead SSOP package.

Feature Summary

• Integrates a high-performance 10-bit pipeline ADC architecture with an on-chip track-and-hold circuit.
• Supports configurable analog input voltage ranges of 1 V p-p or 2 V p-p via the DFS/GAIN pin.
• Features a separate digital output driver supply to accommodate various logic families.
• Includes a low-power sleep mode that significantly reduces energy consumption.

Applications

• Battery-powered instruments
• Hand-held scopemeters
• Low-cost digital oscilloscopes
• Ultrasound equipment
• Cable reverse path

Procurement Notes

Verify the specific suffix 'BRS-RL105' against the manufacturer's official ordering guide to confirm it corresponds to the AD9214-105 variant with reel packaging. Ensure the component meets industrial temperature range requirements (-40°C to +85°C) if applicable to your design. Cross-reference the datasheet revision E specifications for accuracy regarding AC performance metrics before finalizing procurement.

Selection Notes

Select this component when a 10-bit resolution and up to 105 MSPS sampling rate are required within a small form factor. It is suitable for applications needing low power consumption and single-supply operation. Consider the 1 V p-p or 2 V p-p input range options based on the signal source characteristics. Ensure the system clock jitter is minimized to maintain the specified SNR performance levels.

Part Context

The AD9214 is part of Analog Devices' portfolio of low-cost, low-power monolithic ADCs. It utilizes a bit-per-stage pipeline architecture with switch-capacitor techniques. The device is designed for ease of use, requiring no external reference or driver components for many applications. It is fabricated on an advanced CMOS process technology.

Replacement Considerations

Check for AD9214-65 or AD9214-80 variants if lower sampling rates suffice. Verify pin compatibility with other 10-bit ADCs in the same package family. Ensure replacement parts support the required 105 MSPS speed and 300 MHz analog bandwidth.
