AD9214BRSZ-RL80

Overview

The AD9214BRSZ-RL80 is a 10-bit monolithic sampling analog-to-digital converter (ADC) from Analog Devices Inc., optimized for low cost, low power, and small size. It operates at a maximum conversion rate of 80 MSPS with an analog input bandwidth of 300 MHz. The device features an on-chip track-and-hold circuit and requires only a single 3.3 V supply (2.7 V to 3.6 V). It offers configurable analog input ranges of 1 V p-p or 2 V p-p and supports both two's complement and offset binary data formats. Digital outputs are TTL/CMOS compatible via a separate DrVDD pin.

Feature Summary

• Integrated track-and-hold circuit and internal reference simplify system design by eliminating external driver components.
• Configurable analog input range allows selection between 1 V p-p and 2 V p-p differential signals via the DFS/GAIN pin.
• Separate digital output driver supply enables compatibility with various logic families such as 3.3 V or 2.5 V systems.
• Power-down mode reduces consumption to 30 mW, supporting battery-powered applications.

Applications

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

Procurement Notes

Verify the specific suffix RL80 against official documentation to confirm it denotes the reel packaging format for the 80 MSPS variant. Ensure the ordering code matches the required speed grade and package type. Confirm RoHS compliance status if environmental regulations apply to the target deployment environment.

Selection Notes

Select this component when a 10-bit resolution and 80 MSPS sampling rate are required within a compact form factor. Consider the 28-lead SSOP package constraints for PCB layout. Evaluate the 300 MHz analog bandwidth against the highest frequency component of the input signal to ensure adequate performance margins.

Part Context

The AD9214 belongs to Analog Devices' family of high-speed, low-power monolithic ADCs. It utilizes a bit-per-stage pipeline architecture with switch-capacitor techniques. This series is designed for applications demanding outstanding dynamic performance while minimizing power consumption and board space requirements.

Replacement Considerations

Check for AD9214-65 or AD9214-105 variants if different sampling rates are acceptable. Verify pinout compatibility before substitution. Ensure that any replacement part maintains the same 28-SSOP package dimensions and electrical interface specifications.
