8 Detailed Description
8.1 Overview
The INA851 is a monolithic, precision instrumentation amplifier that incorporates a current-feedback input stage
and a four-resistor, fully differential amplifier output stage. The schematic in Figure 8-1 shows how the differential
input voltage is buffered by Q1 and Q2, and is forced across RG, which causes a signal current to flow through
RG, R1, and R2. The fully differential amplifier, A3, removes the common-mode component of the input signal and
refers the output signal to the VOCM pin. The VBE and voltage drop across R1 and R2 produce output voltages
on A1 and A2 that are approximately 0.8 V less than the input voltages.
