AD9214BRS-RL65

Overview

The AD9214BRS-RL65 is a 10-bit monolithic sampling analog-to-digital converter (ADC) from Analog Devices Inc. It operates at a maximum conversion rate of 65 MSPS with an analog input bandwidth of 300 MHz. The device requires a single 3.3 V supply (2.7 V to 3.6 V) and consumes 190 mW at the rated speed, reducing to 30 mW in power-down mode. It features an on-chip track-and-hold circuit and reference, supporting differential or single-ended inputs with selectable 1 V p-p or 2 V p-p ranges. Digital outputs are TTL/CMOS compatible via a separate DrVDD pin.

Feature Summary

• Integrated track-and-hold and internal voltage reference eliminate external driver components for many applications.
• Single 3.3 V supply operation simplifies system power design while accommodating 2.5 V logic families.
• Configurable data format options include two's complement and offset binary modes.
• Small 28-lead surface-mount plastic package optimizes board space.

Applications

• Battery-powered instruments
• Hand-held scopemeters
• Low-cost digital oscilloscopes
• Ultrasound equipment
• Broadband wireless systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the reel packaging configuration. Ensure the component meets RoHS compliance requirements for your region. Cross-reference the full part number with the authorized distributor catalog to validate current availability status before finalizing procurement plans.

Selection Notes

Select this model when a 65 MSPS sampling rate satisfies the Nyquist requirement for the target signal frequency. Evaluate the 1 V p-p versus 2 V p-p input range options based on the source signal amplitude to optimize dynamic performance. Consider the separate DrVDD supply pin if interfacing with logic families other than standard 3.3 V CMOS.

Part Context

This component belongs to the AD9214 family of high-speed, low-power ADCs. Variants within the series support different maximum sampling rates, including 80 MSPS and 105 MSPS models. All variants share the same 10-bit resolution, pipeline architecture, and 28-SSOP package form factor, differing primarily in clock speed specifications.

Replacement Considerations

Direct functional substitutes within the same family include the AD9214-80 and AD9214-105, which offer higher sampling rates but maintain identical pinouts and electrical characteristics. Verify that the application timing constraints accommodate the faster clock speeds if upgrading to these variants.
