AD9236BCP-80

Overview

The AD9236BCP-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 utilizes a multistage differential pipelined architecture with output error correction logic to provide 12-bit accuracy at 80 MSPS and guarantees 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) with a separate digital output driver supply (2.25 V to 3.6 V). Key performance metrics include an SNR of 70.4 dBc to Nyquist, SFDR of 87.8 dBc to Nyquist, and low power consumption of 366 mW.

Feature Summary

• Multistage differential pipelined architecture with output error correction logic for 12-bit accuracy
• High-performance sample-and-hold amplifier with 500 MHz bandwidth
• On-chip voltage reference and clock duty cycle stabilizer
• Flexible analog input supporting differential or single-ended configurations

Applications

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

Procurement Notes

Verify the specific package type when ordering, as the AD9236 is available in both 28-lead TSSOP and 32-lead LFCSP packages. Ensure the suffix matches the required pin configuration and thermal characteristics. Confirm that the selected variant meets the industrial temperature range specifications of -40°C to +85°C for your application environment.

Selection Notes

Select the AD9236BCP-80 for applications requiring high-speed data conversion with low power consumption. The device supports both offset binary and two's complement data formats. Consider the separate DRVDD supply for compatibility with 2.5 V and 3.3 V logic families. The pin-compatible nature with AD9215, AD9235, and AD9245 allows for simplified migration across different resolution and speed requirements.

Part Context

The AD9236 is part of Analog Devices' portfolio of high-speed analog-to-digital converters. It is designed for applications requiring high dynamic range and low power consumption. The device is fabricated on an advanced CMOS process and is specified over the industrial temperature range. It offers a flexible analog input interface and includes features such as an out-of-range indicator and a clock duty cycle stabilizer.

Replacement Considerations

The AD9236 is pin compatible with the AD9215, AD9235, and AD9245. This allows for simplified migration from 10 bits to 14 bits and from 20 MSPS to 80 MSPS. When selecting a replacement, ensure that the pinout and package dimensions match the original design to facilitate direct substitution without PCB modifications.
