Dual general-purpose operational amplifier

Transcription

1 NE/SA/SE DESCRIPTION The is a dual operational amplifier that is internally compensated. Excellent channel separation allows the use of a dual device in a single amp application, providing the highest packaging density. The NE/SA/SE is a pin-for-pin replacement for the RC/RM/RV. FEATURES MHz unity gain bandwidth guaranteed Supply voltage ±V for SE and ±V for NE Short-circuit protection No frequency compensation required No latch-up Large common-mode and differential voltage ranges Low power consumption PIN CONFIGURATIONS D and N Packages A OUT V+ A IN A 7 + B OUT A IN+ V B + B IN IN+ ORDERING INFORMATION DESCRIPTION TEMPERATURE RANGE ORDER CODE DWG # -Pin Plastic Small Outline (SO) Package to +7 C NED 7C -Pin Plastic Dual In-Line Package (DIP) to +7 C NEN B -Pin Plastic Dual In-Line Package (DIP) - to + C SAN B -Pin Plastic Dual In-Line Package (DIP) - to + C SAD B -Pin Plastic Dual In-Line Package (DIP) - to + C SEN B EQUIVALENT SCHEMATIC v + () INPUTS () + OUYPUT (7) V August, 99-7

Derate above C at the following rates: N package at 9.mW/ C D package at.mw/ C. For supply voltages less than ±V, the absolute maximum input voltage is equal to the supply voltage.. Short-circuit may be to ground on one amp only. Rating applies to + C case temperature or +7 C ambient temperature for NE and to + C ambient temperature for SA.
