AD9214BRS-RL80

Overview

The AD9214BRS-RL80 is a 10-bit monolithic sampling analog-to-digital converter (ADC) from Analog Devices Inc. It operates at a maximum conversion rate of 80 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 220 mW at the rated speed. It includes an on-chip track-and-hold circuit, internal reference, and supports both two's complement and offset binary data formats. The component is housed in a 28-lead SSOP package.

Feature Summary

• Integrated track-and-hold circuit and internal voltage reference for simplified system design
• Configurable analog input range supporting either 1 V p-p or 2 V p-p differential signals
• Separate digital output driver supply pin allows compatibility with 2.5 V or 3.3 V logic families
• Dedicated power-down mode reduces power consumption to 30 mW

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 selected variant matches the required 80 MSPS performance tier within the AD9214 family. Cross-reference the datasheet revision history to validate current specifications before finalizing procurement orders.

Selection Notes

Select this model when an 80 MSPS sampling rate is required alongside low power consumption constraints. Consider the separate DrVDD supply pin if interfacing with logic families operating at voltages different from the main analog supply. Evaluate the available analog input ranges to determine if external attenuation or amplification is necessary for the target signal swing.

Part Context

This component belongs to the AD9214 series of high-speed, low-power ADCs. The series offers variants optimized for 65 MSPS, 80 MSPS, and 105 MSPS operation. All members share the same 28-lead SSOP package and architectural features, differing primarily in their maximum clock frequencies and associated dynamic performance metrics.

Replacement Considerations

Direct replacements include other AD9214 variants such as the AD9214-65 or AD9214-105, provided the system timing requirements align with their respective maximum sampling rates. Verify that the pinout and electrical characteristics remain identical across the family to ensure drop-in compatibility.
