AD9214BRSZ-RL65

Overview

The AD9214BRSZ-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 features a single 3.3 V supply operation (2.7 V to 3.6 V) and consumes 190 mW at the rated speed. It includes 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 reference circuits simplify system design by eliminating external components for many applications.
• Configurable analog input range allows selection between 1 V p-p and 2 V p-p full-scale signals via the DFS/GAIN pin.
• Separate digital output driver supply enables compatibility with both 3.3 V and 2.5 V logic families.

Applications

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

Procurement Notes

Verify the specific suffix 'RL65' against official documentation to confirm reel packaging and tape specifications. Ensure the component matches the industrial temperature range requirements of -40°C to +85°C. Confirm that the ordering code corresponds to the 65 MSPS variant rather than the 80 or 105 MSPS versions.

Selection Notes

Select this model when a 10-bit resolution at 65 MSPS is required with low power consumption. Consider the internal reference capability if external voltage references are undesirable. Evaluate the 300 MHz analog bandwidth against the highest frequency component of the input signal to ensure adequate performance.

Part Context

This component belongs to the AD9214 family of high-speed, low-power ADCs. The 'BRSZ' designation indicates a plastic SSOP package, while the '-RL65' suffix specifies the 65 MSPS speed grade and reel packaging format within the Analog Devices product line.
