Instrumentation amplifier output voltage
NettetLinear operation of an instrumentation amplifier depends upon linear operation of its building block: op amps. An op amp operates linearly when the input and output signals … NettetThe R bias value can be calculated using Equation 2 where the voltage reference, V ref, and the common mode voltage, V cm, are equal when V ref is connected directly to the non-inverting op amp input. V in is the output voltage of the power supply and R 1 is the input resistor of the voltage divider.

NettetA circuit includes an operational amplifier and a resistor network coupled to an output of the operational amplifier. The resistor network includes a first set of resistors coupled between the output of the operational amplifier and a first node of the resistor network, wherein the resistors of the first set are electrically connected in series with each other, … NettetBecause the common mode voltage is being amplified by A1, the input common mode rangeis severely restricted by the output swing of A1. The problem is especially acute in applications where low voltage sup-plies are mandatory, The use of rail-to-rail amplifiers will improve matters somewhat by adding some more headroom.

NettetIt is well known that the instrumentation amplifier transfer function in Figure 1 is. (1) when R5 = R6, R2 = R4 and R1 = R3. The proof of this transfer function starts with the Superposition Theorem. Let’s make V2 zero by connecting the U2 input to ground, and let’s calculate Vout1 (see Figure 2). Figure 2. Nettetvoltage, Vod. The output common-mode voltage, Voc, is the average of the two output voltages, and is controlled by the voltage at Vocm. With a(f) as the frequency-dependant differential gain of the amplifier, then Vod = Vid × a(f).

A good rule of thumb when using a 100 kohm/100 kohm voltage divider, as shown, is to use a C2 value of at least 10 μF for a 0.3-Hz –3-dB roll-off. A value of 100 μF (0.03-Hz pole) should be sufficient for practically all …
NettetThe instrumentation amplifier gain equation can then be expressed as the following: Av = V o V 2 − V 1 = (1 + 2R2 Rgain)( R4 R3) A v = V o V 2 − V 1 = ( 1 + 2 R 2 R g a i n) ( …
