AD632SH/883B 概述
An analog multiplier is a circuit that produces an output voltage proportional to the product of two input voltages. The AD632 is a four-quadrant multiplier, meaning it can handle both positive and negative input signals, enabling applications such as modulation, demodulation, automatic gain control, and power measurement. As a precision analog computational building block, it sits within the broader category of analog signal processing ICs, which are essential in instrumentation, control systems, and communication equipment.
Key features include excellent long-term stability, low noise, and high reliability. The device is internally trimmed for accuracy, reducing the need for external calibration. The fully differential Z-input allows flexible signal conditioning, and the ability to achieve gains up to ×10 simplifies system design. The TO-100-10 metal can package provides hermetic sealing, making it suitable for harsh environments.
Technically, the AD632 uses a monolithic bipolar process with laser-trimmed thin-film resistors to achieve high accuracy. The transfer function is W = (X1 - X2)(Y1 - Y2)/10V + Z, where Z is the differential Z-input. This architecture supports multiplication, division, squaring, and square-rooting functions. The device is designed for precision analog computation, with a typical nonlinearity of ±0.5% and a small-signal bandwidth of 1 MHz.
Typical applications include analog computation in test and measurement equipment, precision power measurement, process control, and signal conditioning in military and aerospace systems. The AD632SH/883B is particularly suited for applications requiring high accuracy and stability over a wide temperature range.
When designing with this device, ensure proper power supply decoupling with 0.1 µF ceramic capacitors close to the supply pins. The output can drive loads down to 2 kΩ, and the Z-input can be used for offset adjustment or to sum signals. For division mode, the Y-input must be positive to avoid instability.

设计说明
The AD632SH/883B requires dual power supplies, typically ±15 V. Use 0.1 µF ceramic capacitors close to the V+ and V- pins for decoupling. Additionally, a 10 µF tantalum capacitor on each supply rail is recommended to filter low-frequency noise. Ensure the supplies are clean and stable to maintain accuracy.
For the TO-100-10 metal can package, ensure proper heat dissipation. The metal can is connected to the substrate, so it can be soldered to a PCB pad for thermal relief. Keep input and output traces short to minimize parasitic capacitance. Use a ground plane to reduce noise pickup.
In division mode, the Y-input must be positive to avoid instability. Also, the output can drive loads down to 2 kΩ; driving lower impedances may cause distortion. Do not exceed the absolute maximum supply voltage of ±18 V. Always verify the pinout against the datasheet before layout.
