100% brand new LTC2400 24bit ADC Module with 4.096V precision reference


This 24bit ADC Module is designed for Arduino or other embedded systems to acheive high resolution analoge to digital conversion. The module use LTC2400 24bit ADC IC and TI REF3040 4.096V precision reference. The PCB and components are designed to minimize noise interference.
A p-p noise of 20uV can be achieved when measuring two AA batteries using a USB power source.
Noise can be further reduced by using a linear 5V power source.

The PCB is designed to fit into Arduino UNO SPI interface, connection is therefore the minimum.
Arduino sketch and demo is also included.
The demo using UART TFT LCD can also be played in youtube:

Review and user manual is HERE

With this ADC Module, you can turn your arduino into a 6 digit voltmeter and also achieve high resolution measurement of analog sensors.
E.g. temperature measurement using NTC, analog output temperature IC, pressure sensor, sound sensor, light intensity sensor, humidity sensor etc.

The reference IC can be replaced by a more accurate and lower drift 5.000V reference IC REF195E, it is HERE
