| Market Reality | The AD620 is the instrumentation amplifier of medical front ends, load cells, thermocouples and every bridge sensor that needed clean differential gain from an eight-pin body - one external resistor sets gains from 1 to 10000, and the part has been the reference point of its class since the 1980s. Its replacement story is unusually polite: the AD8221 was introduced as the higher-performance pin-compatible successor with the SAME gain formula, so the gain resistor carries over; the AD623 opens the single-supply world at lower cost with a DIFFERENT gain formula, so the resistor does not carry over. The family rule for repair is one sentence: the socket is generous, the gain math is not. | The AD620 is the instrumentation amplifier of medical front ends, load cells, thermocouples and every bridge sensor that needed clean differential gain from an eight-pin body - one external resistor sets gains from 1 to 10000, and the part has been the reference point of its class since the 1980s.
