AD9214BRSZ-105

Analog To Digital Converters (ADC) Overview

The AD9214BRSZ-105 is a 10-bit monolithic sampling analog-to-digital converter (ADC) operating at a maximum conversion rate of 105 MSPS. It features a single 3.3 V supply (2.7 V to 3.6 V) and includes an on-chip track-and-hold circuit and reference. The device offers a 300 MHz analog bandwidth and supports differential or single-ended inputs with selectable 1 V p-p or 2 V p-p ranges. Digital outputs are TTL/CMOS compatible, powered by a separate DrVDD supply (2.7 V to 3.6 V). It is housed in a 28-lead SSOP package and operates within the -40°C to +85°C temperature range.

Analog To Digital Converters (ADC) Feature Summary

• Single 3.3 V supply operation simplifies system power design.
• On-chip track-and-hold and reference reduce external component requirements.
• Separate digital output driver supply accommodates various logic families.
• Low power consumption with a dedicated power-down mode.

Analog To Digital Converters (ADC) Applications

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

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'R' against the manufacturer's official documentation to confirm reel packaging status, as standard datasheets may list tube packaging for the base part number. Ensure the ordering code matches the exact speed grade and package variant required for your design. Cross-reference the revision history for any recent manufacturing changes that might affect pin compatibility or electrical characteristics.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a 105 MSPS sampling rate is required for high-speed signal acquisition. Consider the internal reference capability if external voltage references are undesirable. Evaluate the power consumption at 285 mW against system thermal constraints. Verify that the 28-SSOP package dimensions fit the available PCB real estate and that the TTL/CMOS interface aligns with the downstream processing logic levels.

Analog To Digital Converters (ADC) Part Context

The AD9214 belongs to Analog Devices' family of low-cost, low-power 10-bit ADCs. It shares architectural similarities with the AD9215 but differs in power consumption and specific performance metrics. This series is designed for applications requiring moderate resolution and high speed without the complexity of multi-channel or higher-resolution converters.

Analog To Digital Converters (ADC) Replacement Considerations

The AD9214BRUZ-105 is a direct pin-compatible alternative in a TSSOP-28 package. The AD9215BRUZ-105 offers similar functionality but with different power specifications. Verify package footprint differences between SSOP and TSSOP before substitution.
