Output
Internal gain-set resistors are provided for gains of 1,
10, 100, 200, and 500V/V. Inputs are protected for
differential and common-mode voltages up to ±V_CC.
Its very high input impedance and low input bias
current make the INA110 ideal for applications
requiring input filters or input protection circuitry.
