MPY100SG

Overview

The MPY100SG is a precision multiplier-divider integrated circuit manufactured by Texas Instruments, housed in a 14-pin ceramic DIP package. It supports an extended industrial temperature range from -55°C to +125°C. The device performs four-quadrant multiplication, division, squaring, and square root operations without external trimming. Key electrical specifications include a small-signal bandwidth of 550 kHz, a full-power bandwidth of 320 kHz at ±10V output, and a slew rate of 20 V/µs. It operates with supply voltages up to ±20VDC and features low noise performance.

Feature Summary

• Differential input architecture supporting four-quadrant analog computation
• Laser-trimmed one-chip design ensuring high reliability and guaranteed accuracy
• Integrated internal reference eliminating the need for external potentiometers
• Wide operating temperature range suitable for demanding industrial environments

Applications

• Analog signal processing and algebraic computation
• True RMS-to-DC conversion circuits
• Bridge linearization and percentage computation
• Instantaneous and real power measurement

Procurement Notes

Verify component authenticity through authorized channels as the MPY100 series has been discontinued or marked as Not Recommended for New Designs (NRND). Confirm that the specific ordering suffix matches the required temperature grade (-55°C to +125°C) and package type (Ceramic DIP). Review current datasheets for any updates regarding lead finish or environmental compliance status before finalizing procurement plans.

Selection Notes

Select the MPY100SG when an extended temperature range beyond standard commercial limits is required. This variant provides the same functional capabilities as the MPY100BG but ensures stable operation in harsher thermal conditions. Ensure the application utilizes dual power supplies within the rated voltage limits and accounts for the ceramic package's thermal resistance characteristics during PCB layout.

Part Context

The MPY100SG belongs to the MPY100 family of precision multiplier-dividers originally developed by Burr-Brown Corporation and later acquired by Texas Instruments. This family includes variants with different accuracy grades and temperature ranges. The SG suffix specifically denotes the extended industrial temperature capability within the ceramic DIP packaging option, distinguishing it from standard commercial versions.

FAQ

What is the maximum capacitive load the MPY100SG 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 does the MPY100SG handle unused input pins?

All unused input pins should be grounded to ensure proper operation and prevent instability.
