LM201 Single Operational Amplifier IC pinout and Examples

LM201 is a general-purpose amplifier that can be used as an advanced alternative of LM741 OP-AMP with an extensive overload protection on the input and the output. It is available in the market as plastic package N DIP 8 and plastic micro package DSO 8. The best advantage it has over internally compensated amplifiers is that the compensation is adjusted in accordance with a particular application. The corresponding family members of LM201 are LM101 and LM301 which differ each other in certain specifications. The slew rate of 10V/µs and bandwidths of 3.5MHz can be obtained with much ease.

LM201 Pinout details

LM201 comes as 8 PIN IC with basic pins for applying inverting and non-inverting inputs and for obtaining the output. DC supply voltage Vcc can vary from ±5 to ±22 Volts.

Where and How to Use LM201

LM201 IC is specially designed to protect when overloaded on input and output. It bypasses the struggle of oscillations and compensations by a simply 30pF capacitor. Higher bandwidth makes it possible to use it as a versatile amplification device. While using LM201 input signal is either applied at inverting or non-inverting input terminals i.e. pin no. 2 or 3. DC supply voltage ranging from 5-22V is applied on pin no. 4 & 7 in such a way that the negative potential of the battery is connected to pin 4 while positive to pin 7. The output voltage is obtained at pin 6. Pin 1, 5 and 8 are used for balancing and compensations. Specific configurations are available to do standard compensation and offset balancing.
