AD9214BRSZ-80

Overview

The AD9214BRSZ-80 is a 10-bit monolithic sampling analog-to-digital converter (ADC) operating at a maximum conversion rate of 80 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. Power consumption is 285 mW at 80 MSPS, with a 30 mW power-down mode. Digital outputs are TTL/CMOS compatible, supported by a separate DrVDD supply for logic interfacing.

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 selection
• Low power consumption with dedicated power-down mode

Applications

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

Procurement Notes

Verify the specific suffix 'R' indicates the reel packaging variant when sourcing components. Confirm that the 'Z' suffix denotes lead-free compliance and RoHS adherence as per manufacturer standards. Ensure the ordering code matches the exact speed grade required for the application timing constraints.

Selection Notes

Select this model for applications requiring 80 MSPS throughput with 10-bit resolution. Consider the 1 V p-p or 2 V p-p input range options based on signal amplitude. Evaluate the separate DrVDD supply requirement if interfacing with non-3.3 V logic families. Verify thermal management needs given the 285 mW power dissipation at full speed.

Part Context

This component belongs to the AD9214 family of high-speed, low-power ADCs from Analog Devices. It shares architectural similarities with the AD9215 but differs in speed grades and package configurations. The part is designed for cost-sensitive, space-constrained designs requiring moderate resolution and high sampling rates.

Replacement Considerations

Direct substitutes include other AD9214 variants such as AD9214-65 or AD9214-105, depending on the required sampling rate. Cross-family replacements like the AD9215 offer similar performance but may require pinout or configuration adjustments.
