High-precision ADC chip AD7792The AD7792 is a 16-bit, high-precision analog-to-digital converter (ADC) with an integrated low-noise sigma-delta (Sigma-Delta) type ADC for excellent conversion accuracy and stability. This enables the AD7792 to accurately convert analog signals to digital signals, suitable for application scenarios requiring high precision.


Low noise: AD7792 has a built-in low noise instrumentation amplifier, which can effectively suppress noise at the input side and improve the signal-to-noise ratio of the signal. This enables the AD7792 to have better performance when measuring weak signals.


Low Power Consumption: The AD7792 is designed with low power consumption, with a typical power consumption of only 400µA, and a maximum power consumption of only 1µA in power saving mode, which enables the AD7792 to maintain low power consumption in long-running applications, and extends the battery life of the device.


The AD7792 has three differential analog input channels that can accept differential signal inputs. Differential inputs can effectively suppress common mode noise and improve signal immunity. This enables the AD7792 to maintain stable performance in complex electromagnetic environments.
