Model: SCXI-1140
Category: 8-channel synchronous sampling differential amplifier module

The 8-channel differential amplifier module for SCXI- the SCXI-1140 provides eight simultaneous sampling input channels and a connection for external sampling to hold the timing signal. The module has a maximum overvoltage protection of ±30 V and is powered on. For applications that require filtering, SCXI-1140 and SCXI-1142 can be cascaded.

The SCXI-1140 8-channel Synchronous Sampling differential amplifier module is an electronic amplifier device with 8 input channels, which can sample input signals synchronously, and can amplify differential signals. A differential amplifier is an electronic amplifier that amplifies the difference between two input voltages at a fixed gain, usually used as a power amplifier or input stage of an emitter-coupled logic circuit.

Input feedback signal at one input end of the differential amplifier and input feedback signal at the other input end can achieve negative feedback, often used for motor or servo motor control, and signal amplification.

The SCXI-1140 is an 8-channel synchronous sampling ADC (analog-to-digital converter) that provides ultra-low input current, allowing direct connection of sensors. Each input channel has a programmable gain stage that maps the low-amplitude sensor output to the full scale ADC input range, maximizing the dynamic range of the signal chain.
