a Features Pretrimmed to ± 0.5% Max 4-Quadrant Error All Inputs (X, Y and Z) Differential, High Impedance for [(X1- X2)(Y1- Y2)/10] + Z2 Transfer Function Scale-Factor Adjustable to Provide up to X10 Gain Low Noise Design: 90 ␮ V rms, 10 Hz- 10 k Hz Low Cost, Monolithic Construction Excellent Long-Term Stability APPLICATIONS High Quality Analog Signal Processing Differential Ratio and Percentage putations Algebraic and Trigonometric Function Synthesis Accurate Voltage Controlled Oscillators and Filters Internally Trimmed Precision IC Multiplier AD632 PIN CONFIGURATIONS H-Package TO-100 D-Package TO-116 PRODUCT DESCRIPTION The AD632 is an internally-trimmed monolithic four-quadrant multiplier/divider. The AD632B has a maximum multiplying error of ± 0.5% without external trims. Excellent supply rejection, low temperature coefficients and long term stability of the on-chip thin film resistors and buried zener reference preserve accuracy even under adverse conditions. The simplicity and flexibility of use provide an attractive alternative approach to the solution of plex control functions. The AD632 is pin-for-pin patible with the industry standard AD532 with improved specifications and a fully differential high impedance Z-input. The AD632 is capable of providing gains of up to X10, frequently eliminating the need for separate instrumentation amplifiers to precondition the inputs. The AD632 can be effectively employed as a variable gain differential input amplifier with high mon-mode rejection. The effectiveness of the variable gain capability is enhanced by the inherent low noise of the AD632: 90 µV rms. PRODUCT HIGHLIGHTS Guaranteed Performance Over Temperature The AD632A and AD632B are specified for maximum multiplying errors of ± 1.0% and ± 0.5% of full scale, respectively at +25°C and are rated for operation from - 25°C to +85°C. Maximum multiplying errors of ± 2.0% (AD632S) and ± 1.0% (AD632T) are guaranteed over the extended temperature range of -...
