Working Principle

The ALD1701BPAL is designed with a non- inverting gain block that provides wide bandwidth, high gain accuracy and superior common-mode rejection over a wide temperature range (from -40°C to +125°C). The amplifier also features a high slew rate of approximately 500V/μs, allowing for the fast acquisition of signals. The device is able to accommodate both high and low output voltage swing and a low distortion level. It is also worth noting that the amplifier is short circuit and thermal overload protected.

In operation, the amplifier is typically connected to an input signal source, such as a transducer, and an output gain device, such as a processor or an analog-to-digital converter. The device amplifies the small transducer signal, which has been filtered and conditioned, and sends out the amplified signal to the application. The gain setting of the amplifier is determined by the feedback resistors, which are typically programmed to meet the desired gain settings. The amplifier’s low input offset voltage and high common-mode rejection allow it to provide low-level signals without distortion or noise.

The ALD1701BPAL is designed to provide a highly linear and accurate signal amplifier solution that is suitable for a wide variety of medical, instrumentation, and industrial applications. It features a high degree of accuracy, good noise and transient performance, and superior common-mode rejection performance. Because of its low cost, high performance, and wide temperature range, the ALD1701BPAL is a great choice for a variety of signal conditioning applications.
