LOW POWER DUAL OPERATIONAL AMPLIFIERS AS358/358A 1 BCD Semiconductor Manufacturing Limited Jan. 2013 Rev. 2. 2 Data Sheet General Description The AS358/358A consist of two independent, high gain and internally frequency compensated operational amplifiers, they are specifically designed to operate from a single power supply. Operation from split power supply is also possible and the low power sup- ply current drain is independent of the magnitude of the power supply voltages. Typical applications include transducer amplifiers, DC gain blocks and most conventional operational amplifier circuits. The AS358/358A series are compatible with industry standard 358. AS358A has more stringent input offset voltage than AS358. The AS358 is available in DIP-8, TDIP-8, SOIC-8, TSSOP-8 and MSOP-8 packages, AS358A is available in DIP-8 and SOIC-8 packages.

Electrical Characteristics (Continued)Note 3: The input common-mode voltage of either input signal voltage should not be allowed to go negatively bymore than 0.3V (at 25oC). The upper end of the common-mode voltage range is VCC-1.5V (at 25oC), but either orboth inputs can go to +36V without damages, independent of the magnitude of the VCC.
Note: Eject hole, oriented hole and mold mark is optional.
