Universal Instrumentation Amplifier Module for SOIC8 Package with On-Board Reference
This is a universal instrumentation amplifier module for SOIC8 package. Various configurations are possible by selecting the right components. The board helps users to develop instrumentation amplifier circuits and it can accommodate SOIC8 devices such as INA828 from Texas Instruments. All capacitors are ceramic type size 0805 and resistors are also size 0805. It supports dual supply or single supply, install R12 0 Ohms for a single supply usage. Various capacitors and resistors can be installed as per application requirements. D1 is the Power LED. Board also has 2.5V precision reference voltage chip. Jumper J1 is provided to select the 2.5V reference voltage to the IN828 Amplifier. An external reference voltage can be fed through CN1 or CN2 Pin 2, Open Jumper J1 in this case. The project also consists of resistors R3, R4, R7, and R8 to create bridge configurations for various sensors. CN3 is provided for sensor input.
