The gain settings are binary weighted (x1, x2, x4, x8, x16, x32, x64) and are selected using simple pin settings. Two sets of external inputs, INA and INB, simplify system design as inputs from a sensor and test DAC. An internal 800 Ω termination can also be se- lected for noise tests. Amplifier input impedance is very high, requiring less than 1 pA of input current. Noise performance is very good at 1 µV p-p between 0.1 Hz and 10 Hz, and a noise density of 8.5 nV/ √Hz over the 200 Hz to 2 kHz band- width. Distortion performance is also extremely good, typically -118 dB THD. Low input current, low noise, and low total harmonic distortion make this amplifier ideal for high impedance differential sensors requiring maximum dynamic range.
