MPY100AG

Overview

The MPY100AG is a precision multiplier-divider integrated circuit manufactured by Texas Instruments, housed in a 14-pin ceramic DIP package. It operates within an ambient temperature range of -25 °C to +85 °C and requires dual power supplies rated at ±15 VDC with an operating range of ±8.5 VDC to ±20 VDC. The device features differential inputs (X1-X2, Y1-Y2) and supports four-quadrant multiplication, division, squaring, and square root operations. Key electrical specifications include a small-signal bandwidth of 550 kHz, a slew rate of 20 V/μs, and a typical noise voltage of 90 μVrms over the 10 Hz to 10 kHz frequency band.

Feature Summary

• Laser-trimmed one-chip design ensuring high reliability and guaranteed accuracy without external trimming requirements.
• Differential input architecture supporting four-quadrant analog signal processing functions including multiplication and division.
• Integrated internal reference and bias circuits eliminate the need for external amplifiers or potentiometers.

Applications

• Four-quadrant multiplication
• Analog division
• True RMS-to-DC conversion
• Bridge linearization

Procurement Notes

Verify current marketing status as the component may be classified as Not Recommended for New Designs (NRND). Confirm package integrity upon receipt, as the ceramic DIP housing requires specific handling precautions during soldering and assembly to prevent mechanical damage.

Selection Notes

Select this component for general-purpose precision analog computation requiring low noise and wide dynamic range. Ensure the application environment remains within the specified -25 °C to +85 °C operational limits. Verify that the required supply voltages align with the ±15 VDC nominal rating and that the load conditions do not exceed the maximum output current capabilities.

Part Context

This part belongs to the MPY100 series of multiplier-dividers produced by Texas Instruments. The 'AG' suffix specifically denotes the 14-pin Ceramic DIP package variant with an industrial temperature range of -25 °C to +85 °C. Other variants in the family include metal TO-100 packages and extended temperature ranges.

FAQ

What is the maximum capacitive load the MPY100AG can drive?

Stable operation is maintained with capacitive loads up to 1000pF in all modes, except for the square root mode where 50pF is the safe upper limit.

How should unused input pins be handled?

All unused input pins must be grounded to ensure proper operation and stability.
