It is suitable for use as part of an interface for capacitive-sensing elements, including precision-level transducer bridges, bridge-type accelerometers and displacement transducers with high capacitance. It can be used as part of a transducer interface for all types of pressure transducers, including piezoresistive, strain-gage, differential-pressure and vacuum-fluid amplifiers.

Working Principles

The XTR116U/2K5G4 features a combination of features designed to maximize the dynamic range of the transducer and minimize the effects of noise, temperature and capacitive coupling. The amplifier contains a low-noise, low-offset transimpedance amplifier circuit, which amplifies small DC signals by converting them to an AC signal, and a connected resistive divider provides gain selection. A unique offset-null circuit adds extra accuracy to the amplifier’s gain and offset adjustments.

The divider consists of two resistive elements: a fixed resistor and an adjustable resistor. The amplifier’s gain is set by selecting the value of the adjustable resistor. The offset-null circuit is activated by applying a voltage signal to the offset-null input pin, which is converted to a current signal by the transimpedance amplifier. The current signal is scaled by the divider resistors and then subtracted from the amplifier’s main signal path.

The XTR116U/2K5G4 also features a high-impedance, wide-bandwidth input stage which helps to reduce the effects of noise and temperature on the signal. The input stage is highly stable over the full temperature range, allowing for accurate Amplifier operation over the full range of temperature. The circuit also includes an overload-protection circuit that limits the maximum output current of the amplifier and prevents damage to the components in the event of an overload.

The XTR116U/2K5G4 is designed to operate over a wide range of input voltages and temperatures. It can operate from a single 5V power supply and supports input voltages of up to 20V. It is rated for a temperature range of -40°C to +85°C, making it suitable for demanding applications.
