AD7150BRMZ Fast response ultra-low power converters
The AD7150 uses a fast-responding, ultra-low-power converter to provide a comprehensive signal processing solution for capacitive short-range sensors. The AD7151 is a lower-power, single-channel form factor of the AD7150.
The AD7150 features Analog Devices' Capacitive-to-Digital Converter (CDC) technology, which combines features that play an important role in interfacing with the actual sensor, such as high input sensitivity, high input parasitic ground capacitance, and leakage current tolerance. An integrated adaptive threshold algorithm compensates for any changes in sensor capacitance due to environmental factors such as humidity and temperature, or aging insulation materials.
By default, the AD7150 operates in standalone mode with a fixed power-up setting and displays the detection results with two digital outputs. In addition, the AD7150 can be connected to a microcontroller via a serial interface, allowing the internal registers to be programmed with user-defined settings and data and status information to be read from the device.
The AD7150 operates from a supply voltage of 2.7 V to 3.6 V and is rated for a temperature range of -40°C to +85°C.
