Analog Microelectronics AM457
AM457 is a high-precision integrated amplifier which has been developed to condition signals from small differential input voltages within a range of a few millivolts (±5 to ±100mV FS). The chief component of the IC is a highly accurate, low-noise amplifier circuit (AMP). The entire system (sensing element plus amplifier) is monitored by the integrated diagnostic unit which logs any sensing element errors or defects, system undervoltage, AMP overloads and excessive temperature.| Part No. | AM457 |
