1_V_HIGH_PRECISION
Drift is less than 1 mV over 20℃ temperature range, and voltage dividet reduces this to ±0.1 mV for 1.00-V reference required in 41/2 -digit meter. All three pots should be wirewound. Current of reference zener is regulated by opamp gain and zener voltage.-S. Kelley, Applications of MC1405/MC14435 in Digital Meters, Motorola, Phoenix, AZ, 1975, AN-748, p 19.
