AD9214BRSZ-65

Overview

The AD9214BRSZ-65 is a 10-bit monolithic sampling analog-to-digital converter (ADC) operating at a maximum conversion rate of 65 MSPS. It features an on-chip track-and-hold circuit and requires only a single 3.3 V supply (2.7 V to 3.6 V). The device offers a 300 MHz analog bandwidth and supports either 1 V p-p or 2 V p-p differential input ranges via the DFS/GAIN pin. Digital outputs are TTL/CMOS compatible, with a separate DrVDD supply for logic interfacing. Power consumption is 190 mW at 65 MSPS, reducing to 30 mW in power-down mode. It is housed in a 28-lead SSOP package.

Feature Summary

• Integrated track-and-hold circuit and internal reference voltage eliminate external components.
• Single 3.3 V supply operation simplifies system power design.
• Configurable analog input range supports both 1 V p-p and 2 V p-p signals.
• Separate digital output driver supply accommodates various logic families.

Applications

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

Procurement Notes

Verify the specific suffix 'R' indicates the reel packaging variant compared to tube versions. Confirm the '-65' designation matches the required 65 MSPS maximum conversion rate. Ensure the ordering code includes the 'Z' suffix for lead-free compliance. Cross-reference the exact part number against the manufacturer's current ordering guide to confirm availability and revision status.

Selection Notes

Select this model when a 65 MSPS sampling rate is sufficient for the application. Consider the 1 V p-p or 2 V p-p input range options based on signal amplitude requirements. Evaluate the 190 mW power consumption against battery life constraints. Verify that the 28-SSOP package dimensions fit the PCB layout. Check if the internal reference meets noise specifications or if an external reference is needed.

Part Context

This component belongs to the AD9214 family of high-speed, low-power ADCs. It shares architectural similarities with the AD9215 and AD9219 but differs in resolution and channel count. The AD9214 specifically targets cost-sensitive applications requiring 10-bit performance. It is often used in conjunction with evaluation boards like the AD9212-65EBZ for development purposes.
