MPY634KU

Overview

The MPY634KU is a wide bandwidth, high accuracy, four-quadrant analog multiplier manufactured by Texas Instruments. It features an accurately laser-trimmed multiplier characteristic for precise signal processing. The device operates with a dual supply voltage range of ±8V to ±18V and draws a typical supply current of 4 mA. It supports a maximum operating frequency of 10 MHz and functions within a temperature range of -40°C to +85°C. The component is housed in a 16-pin SOIC (DW) package with a width of 7.50mm.

Feature Summary

• Four-quadrant analog multiplication capability
• Wide bandwidth performance up to 10 MHz
• High accuracy with laser-trimmed characteristics
• Integrated output amplifier

Applications

• Frequency mixing and modulation
• Automatic gain control circuits
• Phase-locked loops
• Video signal processing

Procurement Notes

Verify the specific suffix 'KU' corresponds to the tape-and-reel packaging variant rather than tube packaging when ordering. Confirm the 16-pin SOIC footprint dimensions match the design layout. Ensure the supply voltage limits are respected to maintain the specified accuracy and bandwidth performance.

Selection Notes

Select this component for applications requiring high-speed analog multiplication with minimal external calibration. Compare against the MPY634KP if through-hole mounting is required instead of surface mount. Consider the 10 MHz bandwidth limit for high-frequency signal processing needs.

Part Context

This part belongs to the MPY634 series of precision analog multipliers. It serves as a surface-mount alternative to the PDIP version, offering the same electrical performance in a compact 16-pin SOIC package. The series is designed for demanding industrial and communication applications.

Replacement Considerations

MPY634KP: Equivalent function in PDIP-14 package. MPY634KUR: Tape-and-reel version of the KU variant.
