opamp amplifier 10
Hello,
I wish to amplify the voltage across the current sense resistor in an SMPS LED driver by a factor of 10.
It's a boost converter LED driver with V(in) = 13.5V
The Op-Amp must be single-supply operational and have facility for rail-to-rail input and output voltages.
I could use an Op Amp set up as a differential amplifier -
-but this means 4 resistors as well as the Op-Amp package itself
Does any reader know of any Times_10 Amplifier IC's which could do this job without me having to add the external resistors?
