Question

A LM307 amplifier has SVRR of 92dB, express it in terms of microvolts per volts?

(a) 65µV/V

(b) 37.98µV/V

(c) 25.12µV/V

(d) 101.4µV/V

I had been asked this question in examination.

Origin of the question is Effect of Variation in Power Supply Voltage on Offset Voltage in section Operational Amplifier Fundamentals of Linear Integrated Circuits

Answer 1

Accurate choice is (c) 25.12µV/V

Expand on the concept with: 20log(1/SVRR)=92dB

=> log(1/SVRR) = 92/20

=> 1/SVRR= 10^4.6

=> SVRR = 1/10^4.6 =25.12µV/V.
