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 multi-
plier 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 film resistors and buried Zener reference preserve accuracy
even under adverse conditions of use. It is the first multiplier to
offer fully differential, high impedance operation on all inputs,
including the Z input, a feature that greatly increases its flexibility
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.

The wide spectrum of applications and the availability of several
grades commend this multiplier as the first choice for all new
designs. The AD534J (±1% maximum error), AD534K (±0.5%
maximum), and AD534L (±0.25% maximum) are specified for
operation over the 0°C to +70°C temperature range. The AD534S
(±1% maximum) and AD534T (±0.5% maximum) are specified
over the extended temperature range, −55°C to +125°C. All
grades are available in hermetically sealed TO-100 metal cans
and SBDIP packages. AD534K, AD534S, and AD534T chips are
also available.

1 Specifications given are percent of full scale, ±10 V (that is, 0.01% = 1 mV).
2 Tested on all production units at final electrical test. Results from those tests are used to calculate outgoing quality levels.
3 Can be reduced down to 3 V using external resistor between –VS and SF.
4 Irreducible component due to nonlinearity; excludes effect of offsets.
5 Using external resistor adjusted to give SF = 3 V.
6 See Figure 1 for definition of sections.
