PIN DESCRIPTION
LM385 IC
The pin diagram of LM358 IC comprises of 8 pins, where
- Pin-1 and pin-8 are o/p of the comparator
- Pin-2 and pin-6 are inverting input/per second
- Pin-3 and pin-5 are non-inverting input/per second
- Pin-4 is GND terminal
- Pin-8 is VCC+
Features of LM358
- It consists of two op-amps internally and frequency compensated for unity gain
- The large voltage gain is 100 dB
- Wide bandwidth is 1MHz
- Range of Single power supply is from 3V to 32V
- Range of dual power supplies is from + or -1.5V to + or -16V
- The supply current drain is very low, i.e., 500 μA
- 2mV low i/p offset voltage
- Common mode i/p voltage range comprises ground
- The power supply voltage and differential i/p voltages are similar
