AD633JNZ

The AD633JNZ from Analog Devices is a functionally complete, four-quadrant analog multiplier. It offers high impedance differential X and Y inputs, along with a high impedance summing input (Z). The device provides a low impedance output voltage with a nominal 10 V full scale, generated by a buried Zener.

Key electrical specifications include a 1 MHz bandwidth and a 20 V/µs slew rate, making it suitable for various applications where simplicity and cost are important. The total error is guaranteed to be within 2% of full scale. Nonlinearity for the Y input is typically less than 0.1%, and output noise is typically less than 100 µV rms in a 10 Hz to 10 kHz bandwidth.

This analog multiplier operates over a supply voltage range of 8 V to 18 V and consumes approximately 4 mA of supply current. It is available in a through-hole PDIP-8 package, with dimensions of 9.27 mm length, 7.24 mm width, and 3.43 mm height. The operating temperature range is -40°C to +85°C.

Applications for the AD633JNZ include multiplication, division, squaring, modulation/demodulation, and phase detection. The Z input provides access to the output buffer amplifier, allowing for increased versatility in configurations such as summing outputs of multiple multipliers or increasing gain.
