Precision Voltage Referance 0.02% LT1019 Testing
This is a precision voltage referance source based on LT1019 (Linear technology referance IC) , it can be used in various projects to provide referance voltage to ADC and DAC as well as it can be used to calibrate 4.5 digit DMM . It can be used to calibrate volt and amp meter based on microcontrollers.
LTC1019 comes with a precise 2.5v oitput for 5.0v we have used INA105 to double 2.5v to precise 5.0v. It is a very precise Op-Amp with laser trimmed internal resistor with accuracy of 0.01%.
