MAX4462HESA+

The MAX4462HESA+ is a 3V/5V, single supply, rail to rail instrumentation amplifier in 8 pin NSOIC package. This instrumentation amplifier implements current feedback design to achieve a precision specification, low power consumption and excellent gain-bandwidth product. This new technique allows ground sensing capability combined with an ultra low input current and an increased common mode rejection performance. The MAX4462 is offered in fixed gain of 100 and has a reference input pin (REF). REF sets the output voltage for zero differential input to allow bipolar signals in single supply applications. It has a high impedance inputs optimized for small signal differential voltages and factory trimmed to gain of 10 with ±0.1% accuracy. Typical applications include strain-gauge amplifier, transducer interface, precision low side current sense, low-noise microphone, preamplifier differential voltage amplification and battery-powered medical equipment.
