AD534TD/883B GENERAL DESCRIPTION

The AD534 is a monolithic laser trimmed four-quadrant multi-plier divider having accuracy specifications previously foundonly in expensive hybrid or modular products. A maximummultiplication error of ±0.25% is guaranteed for the AD534Lwithout any external trimming. Excellent supply rejection, lowtemperature coefficients and long-term stability of the on-chipthin film resistors and buried Zener reference preserve accuracyeven under adverse conditions of use. It is the first multiplier tooffer fully differential, high impedance operation on all inputs,including the Z input, a feature that greatly increases its flexibilityand ease of use. The scale factor is pretrimmed to the standardvalue of 10.00 V; by means of an external resistor, this can bereduced to values as low as 3 V.The wide spectrum of applications and the availability of severalgrades commend this multiplier as the first choice for all newdesigns. The AD534J (±1% maximum error), AD534K (±0.5%maximum), and AD534L (±0.25% maximum) are specified foroperation over the 0°C to +70°C temperature range. The AD534S(±1% maximum) and AD534T (±0.5% maximum) are specifiedover the extended temperature range, −55°C to +125°C. Allgrades are available in hermetically sealed TO-100 metal cansand SBDIP packages. AD534K, AD534S, and AD534T chips arealso available.
