AD9236BRUZ-80

Overview

The AD9236BRUZ-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. The device 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. It operates from a single 3 V power supply (2.7 V to 3.6 V) and consumes low power of 366 mW. The ADC features a differential input with 500 MHz bandwidth, on-chip reference, and flexible analog input ranging from 1 V p-p to 2 V p-p.

Feature Summary

• Multistage differential pipelined architecture with output error correction logic for 12-bit accuracy
• High performance sample-and-hold amplifier (SHA) with wide bandwidth and flexible input configurations
• Integrated clock duty cycle stabilizer (DCS) to maintain performance across varying clock pulse widths
• Separate digital output driver supply to accommodate 2.5 V and 3.3 V logic families

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet revision to confirm package type and temperature grade. Confirm that the component matches the required pinout and electrical specifications for your design. Check for any recent updates or obsolescence notices directly from Analog Devices before finalizing procurement plans.

Selection Notes

Select this component when a 12-bit resolution and 80 MSPS sampling rate are required within a single 3 V supply system. Ensure the application can support the differential input configuration and provides adequate clocking for the internal pipeline delay. Consider the separate DRVDD supply requirement if interfacing with different logic voltage levels.

Part Context

The AD9236 is part of Analog Devices' family of high-speed, low-power analog-to-digital converters. It is pin-compatible with the AD9215, AD9235, and AD9245, allowing simplified migration between different resolutions and speeds within the same product line. This compatibility facilitates design upgrades from 10-bit to 14-bit architectures without significant board layout changes.

Replacement Considerations

The AD9236 is pin compatible with the AD9215, AD9235, and AD9245. These parts allow for simplified migration from 10 bits to 14 bits and 20 MSPS to 80 MSPS within the same package footprint.
