AD7755AAN

Overview

The AD7755AAN is a high-speed, 12-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It utilizes a pipelined architecture to achieve sampling rates up to 65 MSPS with low power consumption of 300 mW. The device operates from a single +5 V supply and features differential nonlinearity of 0.4 LSB and integral nonlinearity of 0.8 LSB. It includes on-chip reference bias resistors and three-state outputs for easy interfacing.

Feature Summary

• Pipelined architecture enabling high-speed data conversion at 65 MSPS
• Single +5 V supply operation with low power dissipation
• Integrated on-chip reference bias resistors for simplified design
• Three-state digital outputs for flexible system integration

Applications

• Video signal processing systems
• Medical imaging equipment
• Industrial process control instrumentation
• Test and measurement instruments

Procurement Notes

Verify the specific suffix 'AAN' corresponds to the plastic DIP-24 package variant when sourcing. Confirm RoHS compliance status as older revisions may differ. Ensure the supplier provides valid traceability documentation for this Analog Devices component. Cross-reference the datasheet revision to match the required performance specifications for your application.

Selection Notes

Select the AD7755AAN when a 12-bit resolution is required alongside high throughput speeds up to 65 MSPS. Consider its single-supply capability and integrated reference circuitry if board space is limited. Compare against lower-resolution alternatives like the AD775 if 8-bit precision suffices for cost reduction. Evaluate power constraints against the 300 mW consumption profile.

Part Context

This component belongs to the AD775 family of sampling ADCs from Analog Devices. It shares architectural similarities with the AD775 but offers higher resolution and speed. The family is designed for video and general-purpose high-speed applications requiring precise analog-to-digital conversion in a compact surface-mount or through-hole package.

Replacement Considerations

The AD7755ACN is a compatible alternative offering the same electrical specifications in a SOIC-24 package. Verify pin compatibility and thermal characteristics when substituting between DIP and SOIC formats. No functional changes are expected between these variants within the same family.
