Data Sheet
FEATURES
Pretrimmed to ±0.25% maximum 4-quadrant error (AD534L) All inputs (X, Y, and Z) differential, high impedance for
[(X1 − X2)(Y1 − Y2)/10 V] + Z2 transfer function Scale factor adjustable to provide up to ×100 gain Low noise design: 90 μV rms, 10 Hz to10 kHz Low cost, monolithic construction Excellent long-term stability
APPLICATIONS
High quality analog signal processing Differential ratio and percentage computations Algebraic and trigonometric function synthesis Wideband, high crest rms-to-dc conversion Accurate voltage controlled oscillators and filters Available in chip form
GENERAL DESCRIPTION
The AD534 is a monolithic laser trimmed four-quadrant multiplier divider having accuracy specifications previously found only in expensive hybrid or modular products. A maximum multiplication error of ±0.25% is guaranteed for the AD534L without any external trimming. Excellent supply rejection, low temperature coefficients and long-term stability of the on-chip thin ...
