Assembly month Lot No. ELM832BW CMOS Low power dual operational amplifier ■Note 1) Common mode input voltage range ELM832BW common mode input voltage range is fixed under the condition of CMRR≥50dB; ELM832BW is able to accept the input above its specification if the degradation of CMRR is not considered. Even if the input voltage exceeds either positive or negative power voltage, troubles such as reverse of output will not occur. As maximum absolute rating, the input voltage is possible within (Vss-0.3)V to (Vdd+0.3)V. 2) Operation from single power source ELM832BW is designed to be most suitable for single power source; therefore, ELM832BW is able to share power supply with logic circuit one. Meanwhile, ELM832BW can also operate from double power sources. To protect power supplies of ELM832BW and logic circuit from noise, please separate wire from power supply and use decoupling (bypass) capacitor. Using the capacitor can improve PSRR characteristics, especially on 10kHz to 100kHz or more. 3) Feedback When OP-AMP circuit is used with feedback resistor, oscillation may happen in the circuit with loop-gain like unity gain follower. a) When large feedback resistance is used, the phase margin is decreased by its combination with the parasitic capacitance of the input part of OP-AMP. In this situation, please connect small capacitor parallelly with feedback resistor as shown in fig-1. b) For capacitive load, external resistor in series connection will be effective as shown in fig-2. (R=300 to 500Ω) c) Being used as an unity gain follow, ELM832B is able to drive capacitive load of 100pF directly without oscillation. b) fig-2 a) fig-1 ��� ��� � ���� ������������� � ������������� � ���� � � �� �� 10 -
