Electrical characteristics
Electrical characteristics
The electrical characteristics given in the following tables are measured under the following
test conditions unless otherwise specified.
Tamb = 25° C, Vcc+ = 5 V, Vcc- connected to Gnd (single-supply configuration).
Vsense = Vp-Vm = 50 mV, Vm = 12 V, no load on Out, all gain configurations.
Rf1, Rf2 and Rf3 resistors are short-circuited.
