Analog Microelectronics AM467
AM467 is a high-precision integrated amplifier which has been developed as signal condition circuit for small differential input voltages within a range of a few millivolts (±5 to ±100 mV FS). The chief component of the IC is a highly accurate, low-noise amplifier circuit which can be adjusted to the sensing elements using an external network of resistors. The rail-to-rail output makes the IC suitable for the amplification of DMS and piezoceramic sensing elements and GMR measuring cells with respect to the specific calibration network.TYPICAL APPLICATIONS
