INA851EVM 2 EVM Circuit Description

This EVM provides access to the features and measures the performance of the INA851. By default, theINA851EVM instrumentation amplifier is configured to a gain of 1 V/V. The evaluation board provides optionalfootprints for gain resistors RG1 and RG2 to modify the input-stage instrumentation-amplifier gain. Optionalfootprints R5 and R9 can be populated with 0-Ω jumpers to set the output stage gain to 0.2 V/V.The INA851 incorporates features that simplify interfacing to a fully-differential ADC. The VOCM connectorsets the output common-mode voltage. If the VOCM connector is not driven, the output common-mode voltagedefaults to the INA851 midsupply value. Clamp pins are provided to limit the INA851 output voltage level,which can be applied to the ADC inputs. The output clamp pins, VCLAMP+ and VCLAMP–, are accessibleusing connector J9. Selectable jumpers J11 and J12 set the output clamp voltage level to the INA851 supplies(default), or to external voltages using connector J9.Revision A of the INA851EVM allows access to the FDA_IN– and FDA_IN+ pins with optional capacitors C7and C18. These capacitors are in parallel with the INA851 output stage internal feedback resistors to implementnoise filtering. A simplified block diagram of the INA851EVM is displayed in Figure 2-1.
