Note 1: Specifications are 100% production tested at +25°C, unless otherwise noted. Limits over temperature are guaranteed by design.
Note 2: Guaranteed by design. Thermocouple and leakage effects preclude measurement of this parameter during production testing.
Note 3: IN+ and IN- are gates to CMOS transistors with typical input bias current of 1pA. CMOS leakage is so small that it is impractical to
Note 4: Setting REF to ground (V
Note 5: This is the REF current needed to directly drive the end terminal of the gain-setting resistors when REFIN/MODE is connected to
Note 6: Output swing high (V
Note 7: Maximum range for V
Note 8: At G = 100V/V and G = 1000V/V, these instrumentation amplifiers are bandwidth limited and not capable of slew-rate-limited dV/dt.
