MAXIM INTEGRATED PRODUCTS  MAX4195ESA+  仪器放大器, 精准, 1个放大器, 100 µV, 0.06 V/µs, 220 kHz, ± 1.35V至± 3.75V, 2.7V至7.5V, NSOIC

The is a micropower rail to rail precision instrumentation amplifier in 8 pin NSOIC package. This 1V/V fixed gain instrumentation amplifier combines rail to rail, single supply operation, outstanding precision specifications and high gain bandwidth. The fixed gain instrumentation amplifier has shutdown function that reduces the quiescent current to 8µA. A traditional three operational amplifier configuration is used to achieve maximum DC precision. The MAX4195 has rail to rail outputs and inputs that can swing to 200mV below the negative rail and to within 1.1V of positive rail. It draws 93µA supply current and low power consumption of this device makes it as Ideal for remote sensing and battery powered applications. It is used in thermocouple amplifier, 4mA to 20mA loop transmitters, data acquisition systems, battery powered equipments, transducer interfaces and bridge amplifier.
