RRIO This operational amplifier offers low voltage noise of
2.9 nV/в€љHz with a 1/f corner of only 3 Hz. The
LMP7731 has bipolar input stages with a bias current
of only 1.5 nA. This low input bias current,
complemented by the very low level of voltage noise,
makes the LMP7731 an excellent choice for
photometry applications.
The LMP7731 provides a wide GBW of 22 MHz while
consuming only 2 mA of current. This high gain …
