GENERAL DESCRIPTION The AD632 is an internally trimmed monolithic four-quadrant rejection. The effectiveness of the variable gain capability is multiplier/divider. The AD632B has a maximum multiplying enhanced by the inherent low noise of the AD632 at 90 V rms. error of 0.5% without external trims. PRODUCT HIGHLIGHTS Excellent supply rejection, low temperature coefficients, and 1. Guaranteed performance over temperature. long-term stability of the on-chip thin film resistors and buried 2. The AD632A and AD632B are specified for maximum zener reference preserve accuracy even under adverse conditions. multiplying errors of 1.0% and 0.5% of full scale, The simplicity and flexibility of use provide an attractive alternative respectively, at +25C and are rated for operation from approach to the solution of complex control functions. 25C to +85C. The AD632 is pin-for-pin compatible with the industry 3. Maximum multiplying errors of 2.0% (AD632S) and standard AD532 but with improved specifications and a fully 1.0% (AD632T) are guaranteed over the extended differential high impedance Z input. The AD632 is capable of temperature range of 55C to +125C. providing gains of up to 10, frequently eliminating the need 4. High reliability. for separate instrumentation amplifiers to precondition the 5. The AD632S and AD632T series are available with MIL- inputs. The AD632 can be effectively employed as a variable STD-883 Level B screening. gain differential input amplifier with high common-mode 6. All devices are available in either the hermetically sealed TO-100 metal can or ceramic DIP package. Rev.
