MAX4461TESA+

The MAX4461TESA+ 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 MAX4461 is offered in fixed gains of 10, uses ground as its reference voltage and has a logic-controlled shutdown input. 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.

• Supply voltage range is 2.85V to 5.25V
