Brand: Fisher

The Fisher 122 is a high-performance analog multiplier and divide-by-two circuit that is used in a variety of engineering applications where precise multiplication and division functions are needed. It operates on a single +5 VDC supply voltage and has a low power consumption, making it ideal for use in low-power designs.The Fisher 122 offers both multiplication and divide-by-two functionality, making it a versatile component for applications that require both functions. This device features a wide analog bandwidth of up to 3 MHz, which enables it to handle high-speed signal processing tasks.In multiplication mode, the Fisher 122 accepts two input signals, multiplies them, and outputs the product. This operation is useful in applications such as spectrum analysis, communications systems, and instrumentation. The multiplication method used by the Fisher 122 is based on a combination of a high-speed analog multiplier and a accurate digital phase shifter.In divide-by-two mode, the Fisher 122 accepts a single input signal and outputs two signals that are half the frequency of the input signal. This functionality is useful in applications such as clock divider circuits and pulse-width modulation (PWM). The divide-by-two function of the Fisher 122 is achieved through a simple recursive divide-by-two scheme.The Fisher 122 offers a number of advantages over other analog multiplier and divide-by-two circuits. These include:- High accuracy: The Fisher 122 offers a maximum multiplication error of 0.25% and a maximum divide-by-two error of 0.15%.- High speed: The Fisher 122 operates at bandwidths up to 3 MHz, making it suitable for high-speed signal processing applications.- Low power consumption: The Fisher 122 consumes only a few milliwatts of power, making it ideal for use in low-power designs.Overall, the Fisher 122 is a versatile and high-performance analog multiplier and divide-by-two circuit that is suitable for use in a wide range of engineering applications. Its low power consumption, high accuracy, and high speed make it a compelling choice for engineers seeking a reliable and efficient solution for multiplication and division tasks.
