AD9214BRSZ-RL105

Overview

The AD9214BRSZ-RL105 is a 10-bit monolithic sampling analog-to-digital converter (ADC) from Analog Devices Inc., operating at a maximum conversion rate of 105 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 analog input ranges via the DFS/GAIN pin. Digital outputs are TTL/CMOS compatible, with a separate DrVDD supply for logic interfacing. It is housed in a 28-lead SSOP package.

Feature Summary

• Integrated track-and-hold circuitry and internal voltage reference minimize external component requirements.
• Configurable analog input range allows selection between 1 V p-p and 2 V p-p full-scale swings.
• Separate digital output driver supply enables compatibility with both 3.3 V and 2.5 V logic families.
• Dedicated power-down mode significantly reduces power consumption when the device is inactive.

Applications

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

Procurement Notes

Verify the specific suffix RL105 against official documentation to confirm reel packaging specifications and tape dimensions. Ensure the ordering code matches the required 105 MSPS speed grade variant within the AD9214 family. Confirm RoHS compliance status and lead-free material declarations prior to procurement.

Selection Notes

Select this model for applications requiring high-speed 10-bit resolution with low power constraints. Evaluate the SNR performance at target input frequencies against system dynamic range requirements. Consider the separate DrVDD supply capability if interfacing with lower voltage logic standards than the primary analog supply.

Part Context

This component belongs to the AD9214 series of high-speed, low-power ADCs. The BRSZ designation indicates a plastic surface-mount package (SSOP) with lead-free termination. The -RL105 suffix typically denotes the 105 MSPS speed bin packaged in a tape and reel format for automated assembly processes.

Replacement Considerations

Direct replacements include other AD9214 variants such as AD9214BRUZ-105 or AD9214BCPZ-105, provided the package type and speed grade match the design requirements. Verify pinout compatibility and electrical specifications before substitution.
