CJMCU-7793 AD7793BRU 3-Channel 24-Bit ADC Low Noise Amplifier Module

CJMCU-7793 AD7793BRU 3-Channel 24-Bit ADC Low Noise Amplifier Module

The CJMCU-7793 AD7793BRU 3-Channel 24-BIT ADC Low Noise Amplifier Module Based on Analog AD7793 chip. The AD7793 are low power, low noise, complete analog front ends for high precision measurement applications. The AD7793 contain a low noise 16-/24-bit -ADC with three differential analog inputs. The on-chip, low noise instrumentation amplifier means that signals of small amplitude can be interfaced directly to the ADC.
