... V THEORY OF OPERATIO The LT1167 is a modified version of the three op amp instrumentation amplifier. Laser trimming and monolithic construction allow tight matching and tracking of circuit parameters over the specified temperature range. Refer to the block diagram (Figure 1) to understand the following circuit description. The collector currents in Q1 and Q2 are trimmed to minimize offset voltage drift, thus assuring a high level of performance ...

... The reference terminal is one end of one of the four 10k resistors around the difference amplifier. The output volt- age of the LT1167 (Pin 6) is referenced to the voltage on the reference terminal (Pin 5). Resistance in series with the REF pin must be minimized for best common mode rejection ...

... ESD strikes up to 13kV (human body). Input Protection The LT1167 can safely handle up to 20mA of input current in an overload condition. Adding an external 5k input resistor in series with each input allows DC input fault voltages up to 100V and improves the ESD immu- nity to 8kV (contact) and 15kV (air discharge), which is the IEC 1000-4-2 level 4 specification ...

... Figure 6. The amplifier, with its gain set to 100, amplifies a differential, full-scale output voltage of 20mV over the industrial range. To make the comparison challenging, the low cost version of the LT1167 will be compared to a discrete instrumentation amp made with the A grade of one of the best precision quad op amps, the LT1114A ...

... The LT1167’s low current noise makes it ideal for high source impedance EMG monitors. Demonstrating the LT1167’s ability to amplify low level signals, the circuit in Figure 8 takes advantage of the amplifier’s high gain and low noise operation. This circuit amplifies the low level nerve impulse signals received from a patient at Pins 2 and 3 ...
