9.1.1 Noninverting Amplifier
The OPA836 and OPA2836 devices can be used as noninverting amplifiers with signal input to the noninverting input, VIN+ . A basic block diagram of the circuit is shown in Figure 8-1.
If VIN = VREF + VSIG, then the output of the amplifier may be calculated according to Equation 1.
The signal gain of the circuit is set by
, and VREF provides a reference around which the input and output signals swing. Output signals are in-phase with the input signals.
The OPA836 and OPA2836 devices are designed for the nominal value of RF to be 1 kΩ in gains other than +1. This gives excellent distortion performance, maximum bandwidth, best flatness, and best pulse response. RF = 1 kΩ must be used as a default unless other design goals require changing to other values. All test circuits used to collect data for this data sheet had RF = 1 kΩ for all gains other than +1. Gain of +1 is a special case where RF is shorted and RG is left open.
