AS633 -
4-quadrant multiplier |
The AD633 is a functionally complete, four-quadrant, analog multiplier.
It includes high impedance, differential X and Y inputs, and a high
impedance summing input (Z). The low impedance output voltage is a
nominal 10 V full scale provided by a laser trimmed bandgap reference.
The AS633 is laser calibrated to a guaranteed total accuracy of 1.5%
of full scale. Nonlinearity for the Y input is typically less than 0.1%
and noise referred to the output is typically less than 100 μV rms in a
10 Hz to 10 kHz bandwidth. A 1 MHz bandwidth, 35 V/μs slew rate, and the
ability to drive capacitive loads make the AS633 useful in a wide
variety of applications where simplicity is a key concern.
The
versatility of the AS633 is not compromised by its simplicity.
The Z
input provides access to the output buffer amplifier, enabling the user
to sum the outputs of two or more multipliers, increase the multiplier
gain, convert the output voltage to a current, and configure a variety
of applications.
AS534 is available only in die form.
