AD620 is a kind of low power instrumentation audio amplifier with low cost, which requires only one external resistor to set gains of 1 to 10000. It features 8-lead SOIC and DIP packaging that is smaller than discrete designs and offers low power, making it a good fit for battery powered, portable or remote applications.
Next it is mainly to introduce the AD620 pinout and AD620 circuit diagram for your demands.
AD620 has 8 pins with individual usage to make the whole chip achieve its function.
The AD620 pinout can be found in the picture below:
also the pin configurations for AD620 are labeled already.
|Pin Number||Pin Name||Description|
|1||Gain (-Rg)||Inverting Gain Terminal connected to resistor to set gain value|
|2||Inverting Input (IN-)||The Inverting input pin of the Op-Amp|
|3||Non- Inverting Input (IN-)||The Non - Inverting Input Pin of Amplifier|
|4||Power (-Vs)||Negative supply terminal|
|5||Reference||Output reference input. Normally connected to common|
|6||Output||Amplifier output pin|
|7||Power (+Vs)||Positive supply terminal|
|8||Gain (+Rg)||Non - Inverting Gain Terminal connected to resistor to set gain value|
AD620 circuit schematic
A circuit schematic can better help us to understand circuits and components used, and it's a reference to make the actual circuit work.
Below is a fully labeled AD620 schematic diagram for reference.
Referring to AD620 Features, the first scene we can think is that it works as instrumentation audio amplifier.
Except that one, there still have some other features and applications we may need to know, which can help us to make use of it well, such as power sensitive applications, calibration and test equipments, low power medical instrumentation, data acquisition devices, control system process. It can operate in single and dual supply voltage, set gain with only one resistor.
