LM741 Operational Amplifier IC
Pin Description
- Pin-1 is Offset null.
- Pin-2 is Inverting (-) i/p terminal.
- Pin-3 is a non-inverting (+) i/p terminal.
- Pin-4 is -ve voltage supply (VCC)
- Pin-5 is offset null.
- Pin-6 is the o/p voltage.
- Pin-7 is +ve voltage supply (+VCC)
- Pin-8 is not connected.
Features
LM741 has only one op-amp inside, there are some op-amp IC’s having more than one op-amp like LM358, LM148, LM248, LM348
Provided with short circuit and overload protection.
Low power consumption.
Large common mode rejection ratio (CMRR) and differential voltage ranges.
No external frequency compensation is required.
Prevent from latch-up when the common-mode range is exceeded.
Minimum, normal and maximum Power Consumption for this IC is ±10v, ±15v and ±22v respectively.
Operating temperature should be -50 to 125 ËšC.
Supply current – 1.7 to 2.8mA.
Soldering pin temperature – PDIP package – 260 ËšC (for 10 seconds – prescribed)
TO-99 and CDIP – 300 ËšC (for 10 seconds – prescribed)
Available packages: TO-99, CDIP & PDIP
