Data Sciences International / Buxco MAX2275 Advance Preamplifier

The MAX2275 is a strain gauge preamplifier module designed for integration into the Buxco MAXII modular data acquisition system. This component amplifies low-level physiological signals with minimal noise, supporting flexible research configurations. The module plugs directly into MAXII enclosures and connects to computer-based A/D cards, with buffered inputs and 6 Volt overvoltage protection.

Technical Specifications The MAX2275 functions as a dedicated strain gauge preamplifier within the MAXII ecosystem. Input protection is rated to 6 Volts. The module integrates into one of two MAXII enclosure options: the MAX1320 (accommodates up to 5 single-width modules and supports 16-channel A/D cards) or the MAX1420 (accommodates up to 12 single-width modules and optionally supports 32-channel A/D cards).

Key Features

Modular design allows flexible configuration within MAXII units

Buffered and overvoltage-protected inputs at 6 Volts

Low-noise signal conditioning for strain gauge applications

Mini-phone jack input connectors on MAXII back panel for analog signal sources

Group Select feature enables channel group switching on 32-channel MAXII units paired with 16-channel A/D cards

Multiple MAXII units can be connected in parallel and stacked for expanded channel capacity

Typical Applications The MAX2275 serves research applications requiring accurate amplification of low-level strain gauge signals. The modular architecture supports single-apparatus setups or multi-channel configurations without hardware rewiring.

Compatibility & Integration The module connects directly to computer A/D cards through the MAXII enclosure. The MAX1320 supports 16-channel A/D cards with up to 16 leads. The MAX1420 supports up to 32 channels with up to 32 leads. Both units feature mini-phone jack connectors for external signal sources and maintain input protection at 6 Volts.
