Two external resistors are used to program the gain. By using matched external resistors, the gain stability of the AD8230YRZ-REEL7 is much higher than instrumentation amplifiers that use a single resistor to set the gain. In addition to allowing users to program the gain between 101 and 1000, users can adjust the output offset voltage.
The AD8230YRZ-REEL7 is versatile yet simple to use. Its auto-zeroing topology significantly minimizes the input and output transients typical of commutating or chopper instrumentation amplifiers. The AD8230YRZ-REEL7 operates on ±4 V to ±8 V (+8 V to +16 V) supplies and is available in an 8-lead SOIC.
