The TC75S67TU from Toshiba is an Ultra Low Noise Single CMOS Operational Amplifier. It requires a supply voltage of 2.2 - 5.5 V and an input offset and bias current of 1 pA. This ultra-compact op-amp provides an output current of ±4 mA, a voltage gain (open loop) of over 80 dB, and a common-mode rejection ratio (CMRR) of 100 dB. It is available in a compact surface-mount package that measures 2.0 x 1.7 x 0.7 mm.
