1. GENERAL INFORMATION

Wide Band Current Amplifiers (WBCA) are variable gain transimpedance amplifiers (current-to-voltage converters) designed for applications that require the conversion of small currents from sensors into voltages .

There are several different configurations of transimpedance amplifiers, each suited to a particular application. Common for all types of transimpedance amplifiers is to convert the low-level current of a sensor to a voltage.

The gain, bandwidth, as well as current and voltage offsets, change with different types of sensors, requiring different configurations of transimpedance amplifiers.

WBCA will provide stable operation in a wide range of requirements to the above conditions.
