The MAX4462HEUT+T from Maxim Integrated Products is a 3V/5V, single supply, rail to rail instrumentation amplifier in 6 pin SOT-23 package. Instrumentation amplifier with precision specifications, low-power consumption and excellent gain bandwidth product. Proprietary design techniques allow ground-sensing capability combined with ultra-low input current and increased common-mode rejection performance. This rail-to-rail output amplifier is offered in fixed gains 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. Also has high-impedance inputs optimized for small-signal differential voltages. Typically used at industrial process control, strain-gauge amplifiers, transducer interface, precision low-side current sense, low-noise microphone preamplifier, differential voltage amplification and battery powered medical equipment.
