16 V Rail-to-Rail, Zero-Drift, Precision Instrumentation Amplifier
Two external resistors are used to program the gain. By using matched external resistors, the gain stability of the AD8230 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 AD8230 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 AD8230 operates on ±4 V to ±8 V (+8 V to +16 V) supplies and is available in an 8-lead SOIC.
