Key Featrues
Rail-to-Rail Output: The MAX4460/MAX4461/MAX4462 instrumentation amplifiers feature rail-to-rail output, enabling the output signal to swing close to the supply rails. This enhances dynamic range and is particularly beneficial in low-voltage applications, such as battery-powered devices, where maximizing signal integrity is critical.
Ultra-Low Input Bias Current (1 pA typ): With an exceptionally low input bias current, these amplifiers minimize errors in high-impedance sensor applications, such as medical equipment or precision current sensing. This feature ensures accurate signal amplification without significant loading effects on the source.
Wide Supply Voltage Range (2.85V to 5.25V): The amplifiers operate efficiently across a broad supply voltage range, making them versatile for both 3V and 5V systems. This flexibility allows for use in diverse applications, from industrial controls to portable electronics.
High Gain-Bandwidth Product (2.5 MHz): The 2.5 MHz gain-bandwidth product ensures high-speed signal amplification with minimal distortion, making these amplifiers suitable for applications requiring fast response times, such as transducer interfaces or strain-gauge amplifiers.
Low Power Consumption (700 µA Supply Current): Designed for low-power operation, these amplifiers are ideal for battery-powered or energy-efficient systems. Their low supply current extends battery life in portable devices while maintaining high performance in precision amplification tasks.
