MAX2037CCQ+

Overview

The MAX2037CCQ+ is an 8-channel variable-gain amplifier (VGA) designed for high linearity, high dynamic range, and low-noise performance in ultrasound imaging and Doppler applications. It features differential inputs and outputs with a total gain range of typically 42dB. The device offers ultra-low output-referred noise of 22nV/√Hz at 5MHz, optimized for interfacing with 12-bit ADCs. Key specifications include a maximum gain of 29.5dB, ±0.25dB absolute gain error, -70dBc HD2, and 120mW consumption per channel. It operates in a 100-TQFP-EP package.

Feature Summary

• Eight-channel configuration providing high integration for ultrasound imaging applications
• Fully differential VGA outputs designed for direct drive to analog-to-digital converters
• Switchable output VGA clamp functionality to eliminate analog-to-digital converter overdrive
• Variable gain range achieving 42dB dynamic range with ultra-low output-referred noise

Applications

• Ultrasound imaging systems
• Doppler applications
• Medical diagnostic equipment

Procurement Notes

Verify the specific suffix against official documentation, as it defines packaging and environmental compliance. Confirm current product status, as this component may be obsolete or subject to supply constraints. Ensure the supplier provides valid traceability and authenticity guarantees. Check for any recent product change notices that might affect pin compatibility or electrical characteristics relative to previous revisions.

Selection Notes

Select this component when designing systems requiring multi-channel signal amplification with precise gain control. It is suitable for applications needing direct interfacing with 12-bit analog-to-digital converters due to its low noise and high linearity. Consider its pin compatibility with related devices like the MAX2038 if system expansion or feature variation is required. Evaluate power consumption per channel against thermal management capabilities.

Part Context

This part belongs to the Maxim Integrated ultrasound variable-gain amplifier family. It shares pin compatibility with the MAX2038, which combines VGA functionality with continuous-wave Doppler beamforming. The series is engineered specifically for medical imaging requirements, offering high integration to reduce board space and simplify design complexity for transducer front-end electronics.

Replacement Considerations

The MAX2038 is a pin-compatible alternative within the same family, offering combined VGA and CW Doppler beamformer functions. Verify functional equivalence regarding gain range, noise performance, and interface requirements before substitution.
