Uses differential amplifier assembled from pair of simple two stage feedback amplifiers having voltage gain of 3. Input sensitivity of meter is 20 meg per v and common mode rejection ratio is 1,000 to 1. Temperature characteristics are reasonably good when using matched let's.-Texas Instruments Inc., Transistor Circuit Design, McGraw-Hill, N.Y., 1963, p 522.
