AD9235BRUZRL7-65

Overview

The AD9235BRUZRL7-65 is a monolithic, single 3 V supply, 12-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 industrial temperature range (-40°C to +85°C). The device features a high-performance sample-and-hold amplifier (SHA) and an on-chip voltage reference. It accepts differential or single-ended analog inputs with a bandwidth up to 500 MHz and offers flexible input ranges from 1 V p-p to 2 V p-p. Digital outputs support offset binary or two's complement formats.

Feature Summary

• Integrated high-performance sample-and-hold amplifier (SHA) and internal voltage reference
• Multistage differential pipelined architecture with output error correction logic
• Flexible analog input configuration supporting both differential and single-ended modes
• On-chip clock duty cycle stabilizer for maintaining performance under varying clock conditions

Applications

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

Procurement Notes

Verify the specific ordering suffix RL7 against the manufacturer's official documentation to confirm reel packaging specifications and tape dimensions. Ensure compatibility with existing board layouts by cross-referencing the pinout with standard TSSOP-28 configurations. Confirm that the component meets all required environmental standards for the intended deployment environment.

Selection Notes

Select this model when a 12-bit resolution and 65 MSPS throughput are required within a single 3 V power supply constraint. Consider the AD9235 family if system upgrades from lower-resolution ADCs are planned, as the pinout is compatible with certain legacy 10-bit devices. Evaluate the need for the internal reference versus external precision references based on system noise requirements.

Part Context

The AD9235 series represents Analog Devices' solution for mid-speed, high-precision data acquisition. Fabricated using advanced CMOS technology, it balances power consumption with performance metrics suitable for portable and battery-operated applications. The BRUZRL7 designation indicates a specific surface-mount variant optimized for automated assembly processes.
