APPLICATION HINTS The LE50A, LE50A voltage references are easier to use than zener diodes. Their low impedance and wide current range facilitate biasing in any cir- cuits. Besides, the breakdown voltage or the tem- perature coefficient can be adjusted so as to opti- mize the performance of the circuit. Figure 1 represents a LE50A with a 10kΩ potenti- ometer to adjust the reverse breakdown voltage which can be adjusted without altering the temper- ature coefficient of the circuit. The adjustment range is generally sufficient to adjust the initial tol- erance of the circuit and the inaccuracy of the am- plifier circuit. To obtain a lower temperature coefficient two di- odes can be connected in series as indicated in Figure 2. When the circuit is adjusted to 2.49V the tempera- ture coefficient is minimized. For a correct temperature coefficient, the diodes should be at the same ambient temperature as the LE50A. The value of R1 is not critical (2-20kΩ).
