... LT6230/LT6230-10/ LT6231/LT6232 U TYPICAL APPLICATIO S The LT6230 is applied as a transimpedance amplifier with an I-to-V conversion gain of 1.5k set by R1. The LT6230 is ideally suited to this application because of its low input offset voltage and current, and its low noise. This is be- cause the 1.5k resistor has an inherent thermal noise of 5nV ...
