Linear - Analog Multipliers, Dividers are the key elements for mixed signal design. The MPY100AG is a commercially available analog gain multiplier circuit which has many applications in signal processing and instrumentation. This article will outline its general working principle and discuss its application fields.

The MPY100AG is a monolithic integrated circuit which contains three internal stages: an analog multiplication stage, an analog division stage and a buffer amplifier stage. The device is specified to operate over a wide range of supply voltage (3 to 15 Volts) with a temperature range of −40 to 125 °C.

The analog multiplication stage consists of three transistors which are connected in a circuit providing gain of up to 10. The analog division stage consists of a pair of complimentary MOSFET transistors which divide the input signal in half. Finally, the buffer amplifier is used to provide an output buffered by a high impedance, thus allowing for extra gain or a voltage divider to be easily applied.

The MPY100AG can be used for a variety of purposes such as gain multiplication, attenuation, bridge balancing, and AC or DC filtering. In applications where the input signal is too large for the operational range of the device, the MPY100AG may be used to proportionally reduce it to the desired level. The MPY100AG can also be used to provide DC offset cancellation by using the analog division stage. In terms of AC filtering, the MPY100AG can be used to apply a low-pass or high-pass filter to the signal.

The main application field of the MPY100AG is within instrumentation and signal processing. It is a key component for various sensors and analog circuit as it is highly reliable and durable, and can be used for applications such as speed control, current/voltage sensing, transducer calibration, and load control. The MPY100AG’s low-voltage operation makes it suitable for battery operated or portable devices. It can also be used in audio processing circuits such as pre-amplification, mixing, and gain stages.

In conclusion, the MPY100AG is a versatile and highly stable analog gain multiplier circuit which has many application fields and working principles. It provides a simple and reliable solution for implementing various signal processing tasks such as amplification, attenuation, AC/DC filtering, and bridge balancing. As a result, the MPY100AG is highly suitable for instrumentation and portable applications.
