The design bines the conventional features of an instrumentation amplifier with a high current output stage. The output remains stable with high capacitance loads (1 μF), a unique ability for an instrumentation amplifier. Consequently, the AMP01 can amplify low level signals for transmission through long cables without requiring an output buffer. The output stage can be configured as a voltage or current generator. Input offset voltage is very low (20 μV), which generally eliminates the external null potentiometer. Temperature changes have minimal effect on offset; TCVIOS is typically 0.15 μV/°C. Excellent low frequency noise performance is achieved with a minimal promise on input protection. The bias current is very low, less than 10 n A over the military temperature range. High mon-mode rejection of 130 d B, 16-bit linearity at a gain of 1000, and 50 m A peak output current are achievable simultaneously. This bination takes the instrumentation amplifier one step further towards the ideal amplifier. AC performance plements the superb dc specifications. The AMP01 slews at 4.5 V/μs into capacitive loads of up to 15 n F, settles in 50 μs to 0.01% at a gain of 1000, and boasts a healthy 26 MHz gain bandwidth product. These features make the AMP01 ideal for high speed data acquisition systems. The gain is set by the ratio of two external resistors over a range of 0.1 to 10,000. A very low gain...
