Ultra-Low Power, 2-Channel, Capacitance

Converter for Proximity Sensing

AD7150

FEATURES

GENERAL DESCRIPTION

Ultra-low power

2.7 V to 3.6 V, 100 μA

Response time: 10 ms

Adaptive environmental compensation

2 independent capacitance input channels

Sensor capacitance (C_SENS) 0 pF up to 13 pF

Sensitivity to 1 fF

EMC tested

2 modes of operation

Standalone with fixed settings

Interfaced to a microcontroller for user-defined settings

2 proximity detection output flags

2-wire serial interface (I²C compatible)

Operating temperature

The AD7150 delivers a complete signal processing solution for

capacitive proximity sensors, featuring an ultra-low power

converter with fast response time. The AD7151 is a single-

channel, lower power alternative to the AD7150.

The AD7150 uses Analog Devices, Inc., capacitance-to-digital

converter (CDC) technology, which combines features

important for interfacing to real sensors, such as high input

sensitivity and high tolerance of both input parasitic ground

capacitance and leakage current.

The integrated adaptive threshold algorithm compensates for

any variations in the sensor capacitance due to environmental

factors like humidity and temperature or due to changes in the

dielectric material over time.

−40°C to +85°C

10-lead MSOP package

By default, the AD7150 operates in standalone mode using the

fixed power-up settings and indicates detection on two digital

outputs. Alternatively, the AD7150 can be interfaced to a

microcontroller via the serial interface, the internal registers can

be programmed with user-defined settings, and the data and

status can be read from the part.

APPLICATIONS

Proximity sensing

Contactless switching

Position detection

Level detection

The AD7150 operates with a 2.7 V to 3.6 V power supply. It is

specified over the temperature range of −40°C to +85°C.
