Order this document by MC4741C/D The MC4741C is a true quad MC1741. Integrated on a single monolithic chip are four independent, low power operational amplifiers which have been designed to provide operating characteristics identical to those of the industry standard MC1741, and can be applied with no change in circuit performance. The MC4741C can be used in applications where amplifier matching or high packing density is important. Other applications include high impedance buffer amplifiers and active filter amplifiers. • Each Amplifier is Functionally Equivalent to the MC1741 • • • • • DIFFERENTIAL INPUT OPERATIONAL AMPLIFIER (QUAD MC1741) SEMICONDUCTOR TECHNICAL DATA Class AB Output Stage Eliminates Crossover Distortion True Differential Inputs 14 Internally Frequency Compensated 1 Short Circuit Protection P SUFFIX PLASTIC PACKAGE CASE 646 Low Power Supply Current (0.6 mA/Amplifier) 14 1 D SUFFIX PLASTIC PACKAGE CASE 751A (SO–14) PIN CONNECTIONS Out 1 1 2 Inputs 1 3 14 * ) 1 4 * ) Out 4 13 Inputs 4 12 Representative Schematic Diagram VCC (1/4 of Circuit Shown) G Noninverting Input VCC 4 5 Inputs 2 6 4.5 k Out 2 ) * 2 3 ) * 7 VEE 10 Inputs 3 9 8 Out 3 25 39 k Inverting Input 11 30 pF 7. 5k (Top View) Output 50 ORDERING INFORMATION Offset Null 1.0 k 50 k 1.0 k 5.0 k 50 k 50 VEE Device Operating Temperature Range Package TA = 0° to +70°C Plastic DIP MC4741CD MC4741CP SO–14 Motorola, Inc. 1996 MOTOROLA ANALOG IC DEVICE DATA Rev 5 1 MC4741C MAXIMUM RATINGS (TA = +25°C, unless otherwise noted.)
