MCP3424 is one of the low noise and high accuracy 18-Bit delta-sigma analog-to-digital (ΔΣ A/D) converter family members of the MCP342X series. Its characteristic is:
Self calibration of internal offset and gain per each conversion.
User can select the PGA gain before the analog-to-digital conversion takes place. This allows the device to convert a very weak input signal with high resolution.
The device have two conversion modes:
- (a)One-Shot mode: the device performs a single conversion and enters a low current standby mode automatically until it receives another conversion command.
- (b)Continuous mode: the conversion takes place continuously at the set conversion speed.
