Sensor Signal Conditioner IC from iC-Haus
May 30, 2010
The iC-TW3 from iC-Haus Corp., Pinckney, MI, is a sensor signal conditioner with temperature compensation and an analog line driver. Precision instrumentation amplifiers with differential voltage inputs service three channels; their gain and offset correction can be individually configured. Gain is adjustable to suit sensor signals in the millivolt range with –3 dB to 59 dB and an integrated regulator automatically triggers the dynamic gain and offset correction. High-impedance inputs let you connect a variety of optical and magnetic sensors to the IC; an automatic offset and gain regulator can be activated for encoder applications. Supply voltage is 3.3–5.0 V, operating temperature range is –40°C to 125°C, and an external EEPROM contains calibration parameters and the temperature compensation interpolation table.
