To configure the device as a noninverting amplifier,
replace R2 and R6 with suitable resistors. Replace
R3 with a short and remove C5 (follow the jumper set-
tings listed in Table 2). The output voltage (V
the noninverting configuration is given by the following
equation:
where:
To configure the device as an inverting amplifier, cut open
the shorted PCB trace on R1. Replace R3 with a short and
remove C5. Replace R1 and R2 with suitable gain resistors
(follow the jumper settings listed in Table 2). An appropri-
