LM324

The LM324 is an inexpensive operational amplifier with a direct differential input, intra-frequency compensation with a single gain and short circuit protection.

In one case of the chip there are four independent operational amplifiers. They have a number of undeniable advantages over the typical operational amplifiers used in circuits with unipolar power.

The chip is manufactured in SOIC and DIP cases and has following characteristics:
Supply voltage:
- unipolar: 3 ... 32 V
- bipolar: 1.5 ... 16 V
Constant voltage gain: 100 dB
Own current consumption: 700 μA
Input bias current (with temperature compensation): 45 nA
Input bias voltage: 2 mV
The range of the input common-mode voltage contains ground
The differential range of the input voltage reaches the supply voltage
Output voltage: 0 to Upt. - 1.5 V
