Hi Folks! I welcome you on board. Thank you for clicking this read. Happy to see you around. In this post today, I’ll walk you through the Introduction to CA3140.
The CA3140 is a general-purpose op-amp that comes with a 4.5MHz frequency. It is a BiMOS Operational Amplifier incorporated with MOSFET Input/Bipolar Output that extends the advantages of both… high-voltage bipolar transistors and high-voltage PMOS transistors on a single integrated chip.
I suggest you read this post all the way through as I’ll detail the complete Introduction to CA3140 covering datasheet, pinout, features, and applications. Let’s jump right in.
Before applying this tiny little beast to your electrical project, it’s better to go through the datasheet of this device that details the main characteristics of the device. You can download the datasheet of CA3140 by clicking the link below.
The following table shows the pin description of CA3140.
Absolute Maximum Rating of CA3140 | ||||
---|---|---|---|---|
Pin No. | Description | Pin Name | ||
1,5 | Used to adjust offset error | Offset Null | ||
2 | Inverting pin of the op-amp | Inverting Input(IN -) | ||
3 | Non-inverting pin of op-amp | Non-inverting Input(IN +) | ||
4 | Ground | GND | ||
6 | Output Pin | Output | ||
7 | Voltage Supply | Vcc | ||
8 | This pin is employed for phase compensation or to turn off the output stage. | Strobe |
The following figure shows the pinout diagram of CA3140.
Two pins (pin# 1 and pin#5) are used to correct the offset error.
The following are some main applications of CA3140.
That was all about CA3140. Hope you find this article helpful.
