AD9215BRUZRL7-65

Overview

The AD9215BRUZRL7-65 is a monolithic, single 3 V supply, 10-bit analog-to-digital converter (ADC) operating at a maximum sampling rate of 65 MSPS. It utilizes a multistage differential pipelined architecture with output error correction logic to ensure no missing codes across the full industrial temperature range of −40°C to +85°C. The device features an on-chip high-performance sample-and-hold amplifier and voltage reference. It operates from a single analog supply (AVDD) of 2.7 V to 3.3 V and a separate digital driver supply (DRVDD) of 2.25 V to 3.6 V. Power consumption is 96 mW at 65 MSPS.

Feature Summary

• Multistage differential pipelined architecture with output error correction logic for guaranteed linearity
• Integrated high-performance sample-and-hold amplifier and internal voltage reference
• Clock duty cycle stabilizer maintains performance over wide variations in clock pulse widths
• Flexible analog input configuration supporting both differential and single-ended modes

Applications

• Ultrasound equipment
• IF sampling in communications receivers
• Battery-powered instruments
• Hand-held scopemeters
• Low cost digital oscilloscopes

Procurement Notes

Verify that the ordering suffix RL7 corresponds to the tape and reel packaging format required for automated assembly processes. Confirm that the specific speed grade indicated by the numeric suffix matches the system timing requirements. Ensure that the component is sourced from authorized distributors to guarantee authenticity and adherence to RoHS3 compliance standards.

Selection Notes

Select this model when a 65 MSPS sampling rate is sufficient for the application bandwidth. The separate DRVDD supply allows compatibility with various logic families. Consider the -80 or -105 variants if higher throughput is needed, noting the associated increase in power dissipation. Verify that the 10-bit resolution meets the dynamic range requirements for the target signal processing chain.

Part Context

This component belongs to the AD9215 family of low-power, 10-bit ADCs manufactured by Analog Devices Inc. The family includes variants optimized for different maximum sampling rates, specifically 65 MSPS, 80 MSPS, and 105 MSPS. All variants share the same pinout and architectural features, facilitating design scalability within communication and medical imaging systems requiring efficient data conversion.

Replacement Considerations

Direct functional replacements within the same package include the AD9215BRU-80 and AD9215BRU-105 series. These alternatives offer higher sampling speeds while maintaining identical pin configurations and interface protocols. System designers must verify that the increased power consumption and thermal characteristics of the faster variants are accommodated by the existing board layout.
