AD9236BCPZRL7-80

Overview

The AD9236BCPZRL7-80 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 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 both 2.5 V and 3.3 V logic families, providing flexibility in system interface design.

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 RL7 corresponds to the reel packaging configuration as defined by Analog Devices. Confirm that the component meets RoHS compliance standards required for your manufacturing process. Ensure the procurement channel provides valid traceability documentation for the Analog Devices Inc. manufacturer. Cross-reference the part number against the latest datasheet revision C to confirm pinout and electrical specifications match your design requirements before finalizing orders.

Selection Notes

Select this component when a 12-bit resolution and 80 MSPS sampling rate are required within a single 3 V supply constraint. The AD9236 is suitable for applications needing a flexible analog input range of 1 V p-p to 2 V p-p. Consider its pin compatibility with the AD9215, AD9235, and AD9245 if migration from lower resolution or speed devices is planned. Evaluate the power consumption of 366 mW against thermal management capabilities in the target enclosure.

Part Context

The AD9236 series includes variants such as the AD9236BRU-80 in a 28-lead TSSOP package and the AD9236BCPZ-80 in a 32-lead LFCSP package. The AD9236BCPZRL7-80 specifically denotes the LFCSP package variant supplied in a reel format. All variants share the same core functionality, including the 12-bit, 80 MSPS specification and industrial temperature range operation from -40°C to +85°C.

Replacement Considerations

The AD9236 is pin compatible with the AD9215, AD9235, and AD9245. These parts allow simplified migration between different resolutions (10 bits to 14 bits) and speeds (20 MSPS to 80 MSPS). Verify that the replacement part's package type and electrical characteristics align with the existing board layout and system requirements.
