SGM8478-1C
High Voltage, High Precision, Low Noise, Over the Rail Difference Amplifier
The SGM8478-1C is a low noise, high precision difference amplifier which can operate from 4.5V to 36V single supply. The device provides rail-to-rail output operation. Its input common mode voltage range covers up to (+VS) + 1V. The wide input voltage range makes this device suitable for current sensing applications.
The SGM8478-1C offers a 16μV maximum input offset voltage. Meanwhile, the device features high linearity and high accuracy. The combination of these characteristics makes the SGM8478-1C a good choice for temperature measurements, pressure and position sensors, strain gauge amplifiers and medical instrumentation, or any other 4.5V to 36V applications requiring precision and long-term stability.
The SGM8478-1C saves external components by integrated matched resistors in differential applications. The gain of SGM8478-1C is 50V/V.
The SGM8478-1C is available in Green SOIC-8 and TDFN-3×3-8L packages. It operates over an ambient temperature range of -40℃ to +125℃.
