Product Details
The AD8230 is a low drift, differential sampling, precision instrumentation amplifier. Auto-zeroing reduces offset voltage drift to less than 50 nV/°C. The AD8230 is well-suited for thermocouple and bridge transducer applications. The AD8230’s high CMR of 110 dB (minimum) rejects line noise in measurements where the sensor is far from the instrumentation. The 16 V rail-to-rail, common-mode input range is useful for noisy environments where ground potentials vary by several volts. Low frequency noise is kept to a minimal 3 μV p-p, making the AD8230 perfect for applications requiring the utmost dc precision. Moreover, the AD8230 maintains its high performance over the extended industrial temperature range of −40°C to +125°C.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.
