SBOU273A February 2022 – November 2022 INA851
By default, the INA851EVM is populated with the INA851 device configured in gain of 1 V/V. However, for flexibility, the PCB layout has additional unpopulated, passive component footprints for gain resistors RG1 and RG2 to set the front-end amplifier gain. Optional footprints for jumper resistors R5 and R6 are provided to set the output stage to gain of 0.2 V/V. In addition, the evaluation board provides footprints R3, R12, C10, C8, and C14 for optional input low-pass filters, and footprints for load resistors R6 and R13. These additional component footprints in the layout allow the user to customize the evaluation circuit. For a full schematic of the INA851EVM, see Figure 7-1.
