MPY100BG 概述
An analog multiplier is a nonlinear signal-processing IC whose output voltage is proportional to the product of two input voltages, placing it in the broader family of analog computational circuits alongside operational amplifiers, log/antilog amplifiers, and voltage-to-frequency converters. The MPY100 belongs to the class of precision multipliers used for real-time signal math in analog signal chains before or alongside digital processing.
Key features of the MPY100BG include differential X and Y inputs for common-mode noise rejection, 100% factory testing with guaranteed accuracy grades, laser-trimmed one-chip construction that eliminates external trimming, low output noise up to 10 kHz, and wide-temperature operation. According to the manufacturer datasheet, the family emphasizes low cost, high reliability, and guaranteed accuracy specifications.
Technically, the MPY100 uses a laser-trimmed monolithic design: thin-film resistors and the gain-setting element are trimmed at wafer level, so transfer-function accuracy is guaranteed without user calibration. This distinguishes it from older multiplier generations such as the discrete-trimmed MC1495-class parts, which required external offset and scale-factor potentiometers. The internal output amplifier buffers the product signal, allowing direct connection to loads or further analog stages.
Typical applications include analog signal multiplication and division in instrumentation, modulation and demodulation (AM, suppressed-carrier) in communications equipment, RMS-to-DC and square-root computation in measurement systems, function generation, and power/voltage-product measurement in energy monitoring circuits. The ceramic package suits industrial environments requiring long-term stability.
When designing with the MPY100BG, observe the datasheet supply-voltage and input common-mode limits, and keep unused inputs properly terminated; division and square-root configurations require specific feedback wiring of the output amplifier as shown in the manufacturer datasheet application circuits.

典型应用
MPY100BG 适用于 6 应用s: Analog Multiplication and Division, Modulation and Demodulation, RMS-to-DC and Square-Root Computation, Industrial Instrumentation and Process Control, Function Generation and Analog Computing, Power and Energy Measurement.
Analog Multiplication and Division
The MPY100BG is purpose-built for real-time analog multiplication and division: four-quadrant operation accepts signals of either polarity on both differential input pairs, and the laser-trimmed 1/10 V scale factor makes the transfer function deterministic without calibration. Because accuracy is 100% tested and guaranteed at the factory, designers can compute products and ratios directly in the signal path for tasks such as power calculation (V x I) or normalization of a measurement by a reference level. Unlike discrete multiplier cells, the on-chip output amplifier eliminates the external op-amp and trimming potentiometers older designs required, reducing board area and error sources. Division and square-root modes use internal feedback wiring per the TI datasheet, keeping the solution to a single 14-CDIP device.
推荐
Modulation and Demodulation
In communications front ends, the MPY100BG implements amplitude modulation, suppressed-carrier modulation, and synchronous detection by multiplying a carrier with a modulation or reference signal. Four-quadrant operation is essential here: the output must swing both polarities as the carrier crosses zero, which single-quadrant parts cannot deliver. The differential X and Y inputs reject common-mode noise picked up on long signal lines, and low noise up to 10 kHz keeps the carrier band clean. Because the part is laser trimmed, carrier feedthrough and scale-factor error stay within the guaranteed grade without board-level calibration, a significant advantage over MC1495-class multipliers that require external offset potentiometers. A post-multiplier low-pass filter recovers the demodulated baseband.
推荐
RMS-to-DC and Square-Root Computation
True-RMS measurement chains square the input signal, average it, and take the square root - and the MPY100BG covers two of those three functions in one device. Wired in the datasheet square-root configuration, it computes the root of an averaged squared signal without external amplifiers or potentiometers, since the laser-trimmed transfer function guarantees accuracy. This suits panel meters, process instrumentation, and audio loudness monitors where crest factor makes average-responding circuits inaccurate. The hermetic ceramic DIP package supports the long-term stability such instruments need, and the 100% factory-tested accuracy grade removes production calibration steps. Polarity limiting in the square-root loop must be respected per the TI datasheet application notes to keep the feedback loop unipolar and stable.
推荐
Industrial Instrumentation and Process Control
Process controllers frequently need analog computation - multiplying a flow signal by a density signal, dividing a measurement by a span reference, or implementing nonlinear control laws - at millisecond speed without firmware. The MPY100BG performs these operations continuously in hardware with guaranteed, factory-tested accuracy, making behavior deterministic and immune to software faults. Its wide-temperature hermetic ceramic DIP package tolerates industrial cabinet environments, and the through-hole leads suit legacy DIN-rail and backplane boards still common in retrofit projects. Differential inputs allow direct connection to transducer conditioning stages with modest common-mode noise. As a legacy Burr-Brown part, it also serves as a form-fit-function replacement in maintaining installed instrumentation originally designed around the MPY100 family.
推荐
Function Generation and Analog Computing
Analog function generators synthesize transfer curves such as parabolas (x squared), ratios, and hypotenuse (square-root of sum of squares) circuits by combining multipliers with summing amplifiers. The MPY100BG is a natural core for these circuits because it integrates the multiplier and output amplifier on one laser-trimmed die: wiring the output back to both X and Y inputs yields squaring per the TI datasheet, and combining two squarers with a third divider unit yields vector-magnitude computation. Guaranteed accuracy without trimming means the synthesized function matches theory to the grade specification immediately at power-up. Educational analog-computer reproductions and hybrid signal-processing test rigs also use the MPY100 family for its low cost and self-contained operation in hermetic DIP.
推荐
Power and Energy Measurement
Instantaneous power equals the product of voltage and current, and the MPY100BG computes that product continuously as a four-quadrant multiplier: one differential input pair receives the scaled voltage waveform, the other the scaled current waveform from a shunt or current transformer. Because both channels accept either polarity, the output faithfully tracks real power through zero crossings and reversing power flow, which half-wave or single-quadrant schemes cannot. The 1/10 V laser-trimmed scale factor makes calibration a matter of input divider ratios, and factory-guaranteed accuracy removes per-unit trimming in production. Averaging the multiplier output yields DC proportional to real power for metering; digitizing it with a delta-sigma ADC supports digital energy registers.

设计说明
Division and square-root configurations use internal feedback of the multiplier into the output amplifier, and these loops are only stable for the signal polarity ranges given in the TI MPY100 datasheet application circuits. Exceeding the polarity limits drives the loop to a rail and can latch the output until power is cycled. Always clamp or offset the denominator input in divider mode so it never crosses zero, and consult the datasheet wiring diagrams rather than assuming op-amp feedback conventions apply unchanged.
As a through-hole ceramic DIP, the MPY100BG benefits from a clean analog ground return: give the X and Y differential input traces short, symmetrical paths and keep switching-regulator or digital clock lines away from the multiplier inputs to preserve the differential common-mode rejection. Use the recommended decoupling from the datasheet on both supply pins with ceramic capacitors placed close to the package, and star-ground at the output amplifier return to prevent ground currents from modulating the 1/10 V scale factor.
Do not substitute grades silently: the MPY100BG is the B accuracy grade, while MPY100AG and MPY100AM carry wider guaranteed error. In a measurement product calibrated against the B-grade budget, dropping to an A-grade part will show as a production yield loss. Conversely, for non-critical modulation tasks the A grade saves cost with identical pinout. Verify the exact grade-specific total error figures in the TI MPY100 datasheet parameter tables before approving any cross within the family.
