MPY634KU

The Texas Instruments MPY634KU is a wide bandwidth, high accuracy, four-quadrant analog multiplier designed for precision analog signal processing. Its accurately laser-trimmed multiplier characteristics simplify integration into various applications, often eliminating the need for external trimming.

The device offers a typical bandwidth of 10MHz and a maximum accuracy of ±0.5%. It operates within a temperature range of -40°C to 85°C. The internal output amplifier reduces design complexity, making it suitable for frequency mixing, balanced modulation, and demodulation with excellent carrier rejection.

With differential X, Y, and Z inputs, the MPY634KU can be configured as a multiplier, squarer, divider, or square-rooter while maintaining high accuracy. The internal voltage reference ensures precise scale factor setting, and the differential Z input allows user-selected scale factors from 0.1 to 10 using external feedback resistors.

Packaged in a 16-SOIC (DW) surface-mount package, the MPY634KU is suitable for applications requiring signal processing at IF, RF, and video frequencies. Its ease of use and low cost make it an attractive option for voltage-controlled amplifiers, voltage-controlled filters, and oscillators.
