MPY100CG

Overview

The MPY100CG is a precision analog multiplier-divider manufactured by Texas Instruments, housed in a 14-pin ceramic DIP package. It supports four-quadrant multiplication, division, squaring, and square root operations without external trimming. The device operates within an ambient temperature range of -25 °C to +85 °C with a rated supply voltage of ±15 VDC. 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. Total error for the B/C grade is typically ±0.5% FSR.

Feature Summary

• Differential input architecture enables accurate four-quadrant multiplication and division functions.
• Laser-trimmed one-chip design ensures high reliability and guaranteed accuracy without requiring external adjustment components.
• Integrated internal reference and bias circuits eliminate common restrictions found in other low-cost multipliers.

Applications

• Analog signal processing
• True RMS-to-DC conversion
• Bridge linearization
• Sine function generation

Procurement Notes

Verify current lifecycle status as the component may be classified as Not Recommended for New Designs (NRND) or Obsolete. Confirm RoHS compliance details and lead finish specifications directly with the manufacturer or authorized distributors before finalizing procurement plans.

Selection Notes

Select this component for general-purpose precision analog computation requiring differential inputs. Ensure the application operates within the specified ±15 VDC supply range and -25 °C to +85 °C temperature limits. Consider the 14-pin CDIP package constraints for through-hole mounting requirements.

Part Context

This part belongs to the MPY100 series of multiplier-dividers from Texas Instruments. It shares functional similarities with variants such as the MPY100BG and MPY100SG, differing primarily in packaging and temperature rating specifications.

FAQ

What is the maximum capacitive load supported by the MPY100CG?

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

How is the divider error minimized in the MPY100CG circuit?

Divider error becomes excessively large for small denominator values; therefore, a 10-to-1 denominator range is usually the practical limit to maintain accuracy.
