MPY634KU/1K

Overview

The MPY634KU/1K is a wide bandwidth, high accuracy four-quadrant analog multiplier manufactured by Texas Instruments. It features laser-trimmed characteristics for precision performance and includes an output amplifier that breaks the traditional bandwidth barrier. The device operates on dual power supplies ranging from 8V to 18V with a maximum operating frequency of 10 MHz. It is housed in a 16-SOIC package with a width of 7.50mm (0.295 inches). The component draws a typical supply current of 4 mA and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Four-quadrant analog multiplication capability
• Wide bandwidth performance with integrated output amplifier
• Laser-trimmed for high accuracy
• Single-ended output configuration

Applications

• Frequency doubling
• Frequency mixing
• Automatic gain control
• Phase-locked loops

Procurement Notes

Verify the specific suffix 'KU/1K' against the manufacturer's official documentation to confirm the exact tape-and-reel quantity and packaging specifications. Ensure the 16-SOIC footprint matches the design layout. Confirm RoHS compliance status through the latest datasheet revision notes before finalizing procurement orders.

Selection Notes

Select this component when high-speed analog signal processing is required. The integrated output amplifier allows for higher bandwidth operation compared to standard multipliers. Verify that the 16-SOIC package size fits the available PCB space and that the thermal dissipation requirements are met within the specified operating temperature range.

Part Context

This part belongs to the MPY series of analog multipliers from Texas Instruments. It is designed for applications requiring precise multiplication of two analog signals. The KU variant denotes the surface-mount SOIC package option, providing a compact solution for modern electronic designs compared to older through-hole packages.

Replacement Considerations

Check for direct pin-compatible replacements such as the MPY634KP or MPY634KUS if different packaging is needed. Verify electrical parameter equivalence, specifically bandwidth and linearity, before substituting.
