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 multi- The wide spectrum of applications and the availability of several plier divider having accuracy specifications previously found grades commend this multiplier as the first choice for all new only in expensive hybrid or modular products. A maximum designs. The AD534J (1% maximum error), AD534K (0.5% multiplication error of 0.25% is guaranteed for the AD534L maximum), and AD534L (0.25% maximum) are specified for without any external trimming. Excellent supply rejection, low operation over the 0C to +70C temperature range. The AD534S temperature coefficients and long-term stability of the on-chip (1% maximum) and AD534T (0.5% maximum) are specified thin film resistors and buried Zener reference preserve accuracy over the extended temperature range, 55C to +125C. All grades are available in hermetically sealed TO-100 metal cans even under adverse conditions of use. It is the first multiplier to offer fully differential, high impedance operation on all inputs, and SBDIP packages. AD534K, AD534S, and AD534T chips are including the Z input, a feature that greatly increases its flexibility also available. and ease of use. The scale factor is pretrimmed to the standard value of 10.00 V by means of an external resistor, this can be reduced to values as low as 3 V. Rev.
