PRODUCTION DATA
The OPA836 and OPA2836 devices can be used as inverting amplifiers with signal input to the inverting input, VIN– , through the gain setting resistor RG. A basic block diagram of the circuit is shown in Figure 8-2.
If VIN = VREF + VSIG, then the output of the amplifier may be calculated according to Equation 2.
The signal gain of the circuit is set by , and VREF provides a reference point around which the input and output signals swing. Output signals are 180° out-of-phase with the input signals. The nominal value of RF must be 1 kΩ for inverting gains.
