AD9214BRS-65

Overview

The AD9214BRS-65 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 features 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 includes an on-chip track-and-hold circuit and reference, supporting 1 V p-p or 2 V p-p differential input ranges. Digital outputs are TTL/CMOS compatible via a separate DrVDD pin.

Feature Summary

• Integrated pipeline architecture with on-chip track-and-hold and reference
• Single 3.3 V supply operation with separate digital driver supply
• Configurable analog input range and data format options
• Low power consumption with dedicated sleep mode

Applications

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

Procurement Notes

Verify the specific suffix 'BRS' against official documentation to confirm package type and temperature grade. Ensure the '-65' designation matches the required 65 MSPS sampling rate for the target application. Cross-reference the ordering guide for availability and lead times directly with the manufacturer.

Selection Notes

Select this model when a 65 MSPS sampling rate is sufficient, as it offers lower power consumption compared to higher-speed variants. Consider the 1 V p-p or 2 V p-p input range requirements based on the DFS/GAIN pin configuration. Verify compatibility with downstream logic levels using the DrVDD supply pin.

Part Context

The AD9214 belongs to a family of low-power, 10-bit ADCs optimized for cost and ease of use. Variants within the series support different maximum sampling rates, including 80 MSPS and 105 MSPS. The AD9214BRS-65 specifically targets applications requiring moderate speed with minimal power draw.

Replacement Considerations

The AD9214-80 and AD9214-105 offer higher sampling rates but consume more power. For direct functional replacement, verify that the 65 MSPS limit meets system timing requirements.
