The amplifier (Fig. 5) includes a first gain stage (QA, QB) comprising a pair of input transistors (QA, QB) and a second gain stage (A1, A2) to drive an output stage (A1, A2). The output stage (A1, A2) provides inverting and non-inverting differential output signals on inverting ...
Figure 1. Differential Amplifier Configured for Balanced (Differential) Inp. For an unbalanced, single-ended input signal (see Figure 2), calculate the input impedance using Equation 1. Figure 2. Differential Amplifier Configured for Unbalanced (Single-Ended) Input. The input impedance of the circui...
again to allow signals of both polarities. That's why the terminal labeled with "VCMADC" isn't connected to signal ground as it is usually done with a differential amplifier but to the common mode voltage of ADC (VCMADC).

A single-ended input to differential-ended output amplifier circuit comprises an amplifier for amplifying an input signal into an amplified signal comprises an input for receiving the input signal; and a first input and a single-ended input to differenti
The differential output signal, Vdiff, is the difference between the two single-ended output signals. Vout+ is the output of the first amplifier and is a buffered version of the input signal, Vin; see Equation (1). Vout- is the output of the second amplifier which uses Vref to add an...
