AD9236BRURL7-80

Overview

The AD9236BRURL7-80 is a monolithic, single-supply, 12-bit analog-to-digital converter operating at an 80 MSPS sampling rate. 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 a high-performance sample-and-hold amplifier and an on-chip voltage reference. It operates from a single 3 V supply (2.7 V to 3.6 V) and consumes 366 mW of power. The ADC provides a differential input with a 500 MHz bandwidth and supports flexible analog input ranges from 1 V p-p to 2 V p-p.

Feature Summary

• Features a patented sample-and-hold amplifier input that maintains excellent performance for input frequencies up to 100 MHz.
• Includes a clock duty cycle stabilizer to compensate for wide variations in clock pulse width while maintaining overall ADC performance.
• Offers a separate digital output driver supply to accommodate both 2.5 V and 3.3 V logic families.

Applications

• High-end medical imaging equipment
• IF sampling in communications receivers
• WCDMA, CDMA-One, and CDMA-2000 systems
• Battery-powered instruments and hand-held scopemeters

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and reel specifications. Ensure compatibility with the required logic family by checking the DRVDD supply requirements. Confirm availability through authorized distributors as stock levels fluctuate. Cross-reference the part number with the latest datasheet revision to verify updated thermal and electrical characteristics before finalizing procurement.

Selection Notes

Select this component when a 12-bit resolution and 80 MSPS throughput are required within a low-power constraint. The device is suitable for applications needing a wide analog input bandwidth and flexible input configurations. Consider the pin compatibility with the AD9215, AD9235, and AD9245 series if migrating from other resolutions or speeds. Evaluate the need for the integrated reference and sample-and-hold amplifier to simplify the external circuit design.

Part Context

The AD9236 belongs to Analog Devices' family of high-speed, low-power analog-to-digital converters. It is designed to bridge the gap between lower-resolution devices like the AD9215 and higher-speed options like the AD9245. The device is fabricated on an advanced CMOS process and is available in both 28-lead TSSOP and 32-lead LFCSP packages. It is specified over the industrial temperature range, making it suitable for a broad range of commercial and industrial applications.

Replacement Considerations

The AD9236 is pin-compatible with the AD9215, AD9235, and AD9245. These parts can serve as direct replacements for migration purposes, allowing transitions between different bit resolutions and sampling rates without redesigning the PCB footprint.

FAQ

What is the pipeline delay of the AD9236?

The AD9236 has a pipeline delay, also known as latency, of 7 cycles.

How does the AD9236 handle out-of-range signals?

The device includes an Out-of-Range (OTR) signal that indicates an overflow condition. This bit can be used in conjunction with the most significant bit to determine whether the overflow is low or high.

Can the AD9236 operate with single-ended inputs?

Yes, the wide bandwidth, truly differential sample-and-hold amplifier allows for user-selectable input ranges and common modes, including single-ended applications.
