The AMP011 is a monolithic instrumentation amplifierdesigned for high-precision data acquisition and instrumentationapplications. The design combines the conventionalfeatures of an instrumentation amplifier with a high currentoutput stage. The output remains stable with high capacitanceloads (1 μF), a unique ability for an instrumentation amplifier.Consequently, the AMP01 can amplify low level signals fortransmission through long cables without requiring an outputbuffer. The output stage can be configured as a voltage orcurrent generator.Input offset voltage is very low (20 μV), which generallyeliminates the external null potentiometer. Temperature changeshave minimal effect on offset; TCVIOS is typically 0.15 μV/°C.Excellent low frequency noise performance is achieved with aminimal compromise on input protection. The bias current isvery low, less than 10 nA over the military temperature range.High common-mode rejection of 130 dB, 16-bit linearity at again of 1000, and 50 mA peak output current are achievablesimultaneously. This combination takes the instrumentationamplifier one step further towards the ideal amplifier.AC performance complements the superb dc specifications. TheAMP01 slews at 4.5 V/μs into capacitive loads of up to 15 nF, settlesin 50 μs to 0.01% at a gain of 1000, and boasts a healthy 26 MHzgain bandwidth product. These features make the AMP01 idealfor high speed data acquisition systems.The gain is set by the ratio of two external resistors over a range of0.1 to 10,000. A very low gain temperature coefficient of 10 ppm/°Cis achievable over the whole gain range. Output voltage swing isguaranteed with three load resistances: 50 Ω, 500 Ω, and 2 kΩ.Loaded with 500 Ω, the output delivers ±13.0 V minimum. Athermal shutdown circuit prevents destruction of the outputtransistors during overload conditions.The AMP01 can also be configured as a high performanceoperational amplifier. In many applications, the AMP01 can beused in place of op amp/power buffer combinations.1 Protected under U.S. Patents 4,471,321 and 4,503,381.
