AD9236BRUZRL7-80

Overview

The AD9236BRUZRL7-80 is a monolithic, single 3 V supply, 12-bit, 80 MSPS analog-to-digital converter featuring a high performance sample-and-hold amplifier (SHA) and voltage reference. It uses a multistage differential pipelined architecture with output error correction logic to provide 12-bit accuracy at 80 MSPS and guarantee no missing codes over the full operating temperature range. The device operates from a single 3 V power supply (2.7 V to 3.6 V) and features a separate digital output driver supply (DRVDD) to accommodate 2.5 V and 3.3 V logic families. At 80 MSPS, it consumes low power of 366 mW. The patented SHA input maintains excellent performance for input frequencies up to 100 MHz and can be configured for single-ended or differential operation.

Feature Summary

• Multistage differential pipelined architecture with output error correction logic ensures 12-bit accuracy and guarantees no missing codes across the full operating temperature range.
• Patented sample-and-hold amplifier (SHA) input supports both single-ended and differential configurations while maintaining excellent performance for input frequencies up to 100 MHz.
• Integrated clock duty cycle stabilizer (DCS) compensates for wide variations in clock pulse widths, maintaining overall ADC performance without requiring precise clock signals.
• Separate digital output driver supply allows compatibility with 2.5 V and 3.3 V logic families, providing flexible interfacing options.

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and reel specifications. Ensure that the DRVDD supply voltage matches the target logic family requirements for proper interface compatibility. Confirm thermal management strategies are adequate for the specified power dissipation levels during continuous operation.

Selection Notes

Select this component when a single 3 V supply operation is required alongside high-speed data conversion capabilities. Consider the pin compatibility with AD9215, AD9235, and AD9245 if migration from lower resolution or speed devices is planned. Evaluate the need for an on-chip reference versus external precision references based on system noise requirements.

Part Context

The AD9236 belongs to Analog Devices' portfolio of high-speed data converters designed for communications and imaging applications. It is part of a family that includes pin-compatible variants like the AD9215 and AD9245, allowing for design flexibility across different resolution and speed requirements within the same footprint constraints.

Replacement Considerations

The AD9236 is pin compatible with the AD9215, AD9235, and AD9245. These parts allow simplified migration between 10 bits to 14 bits and 20 MSPS to 80 MSPS speeds while maintaining the same physical footprint.
