The AD7156BCPZ-REEL is an integrated circuit (IC) component manufactured by Analog Devices. It is a high-performance, fully-integrated, single-supply, low-power capacitance-to-digital converter. It offers significant improvements in signal-to-noise ratio and settling time compared to its predecessors.
One key feature of the AD7156BCPZ-REEL is its high dynamic range, which allows it to accurately measure a wide range of capacitance values. It can detect capacitance changes as small as 0.1 fF (femtofarads) with a resolution of up to 24 bits.
Another notable feature is the device's versatility in different applications. It can be used in proximity sensing, liquid level sensing, touchscreens, and many other capacitive sensing applications. The IC can also support both self-capacitance and mutual capacitance modes, making it suitable for various design requirements.
Additionally, the AD7156BCPZ-REEL offers a low-power operation, making it ideal for battery-powered devices. It has a standby mode, which further reduces power consumption when not in use. Moreover, it supports a wide supply voltage range, from 2.7V to 3.6V, enhancing its flexibility in different power supply configurations.
The IC incorporates an integrated amplifier and an analog-to-digital converter (ADC) with an I²C interface, simplifying system integration
