4.2 Input Signal Path

This section describes the circuitry of the input signal path.

J1 is used to connect IN+ and IN–.

R1 can be used for an optional onboard shunt resistor with a 2512 footprint. Alternatively, a shunt can be placed across the IN+ and IN– terminals of J1. If desired, a differential voltage can be applied directly for measurement tests.

C2, R2, and R3 combine to make an optional input filter. R2 and R3 are populated with 0-Ω resistors by default. When using input filtering, take the input bias current of the device into account. See the data sheet for more information on input filtering.
