APPLICATIONS

Programmable Gain Instrumentation Amplifier Medical Instrumentation Data Acquisition Systems GENERAL DESCRIPTION The AMP02 is the first precision instrumentation amplifier available in an 8-pin package. Gain of the AMP02 is set by a single external resistor, and can range from 1 to 10,000. No gain set resistor is required for unity gain. The AMP02 includes an input protection network that allows the inputs to be taken 60 V beyond either supply rail without damaging the device. Laser trimming reduces the input offset voltage to under 100 µV. Output offset voltage is below 4 mV and gain accuracy is better than 0.5% for gain of 1000. PMI’s proprietary thin-film resistor process keeps the gain temperature coefficient under 50 ppm/°C. Due to the AMP02’s design, its bandwidth remains very high over a wide range of gain. Slew rate is over 4 V/ µs making the AMP02 ideal for fast data acquisition systems. A reference pin is provided to allow the output to be referenced to an external dc level. This pin may be used for offset correc- tion or level shifting as required. In the 8-pin package, sense is internally connected to the output. For an instrumentation amplifier with the highest precision, consult the AMP01 data sheet. For the highest input impedance and speed, consult the AMP05 data sheet. NC = NO CONNECT

REV. D–4– WARNING! ESD SENSITIVE DEVICE CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the AMP02 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.
