PRODUCT DESCRIPTION
The AD534 is a monolithic laser trimmed four-quadrant multiplier 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 which 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% max error), AD534K (±0.5% max)
and AD534L (±0.25% max) are specified for operation over the
0°C to +70°C temperature range. The AD534S (±1% max) and
AD534T (±0.5% max) are specified over the extended temperature range, –55°C to +125°C. All grades are available in her-
metically sealed TO-100 metal cans and TO-116 ceramic DIP
packages. AD534J, K, S and T chips are also available.
PROVIDES GAIN WITH LOW NOISE
The AD534 is the first general purpose multiplier capable of
providing gains up to X100, frequently eliminating the need for
separate instrumentation amplifiers to precondition the inputs.
The AD534 can be very effectively employed as a variable gain
differential input amplifier with high common-mode rejection.
The gain option is available in all modes, and will be found to
simplify the implementation of many function-fitting algorithms

such as those used to generate sine and tangent. The utility of
this feature is enhanced by the inherent low noise of the AD534:
90 µV, rms (depending on the gain), a factor of 10 lower than
previous monolithic multipliers. Drift and feedthrough are also
substantially reduced over earlier designs.
UNPRECEDENTED FLEXIBILITY
The precise calibration and differential Z-input provide a degree
of flexibility found in no other currently available multiplier.
Standard MDSSR functions (multiplication, division, squaring,
square-rooting) are easily implemented while the restriction to
particular input/output polarities imposed by earlier designs has
been eliminated. Signals may be summed into the output, with
or without gain and with either a positive or negative sense.
Many new modes based on implicit-function synthesis have
been made possible, usually requiring only external passive
components. The output can be in the form of a current, if
desired, facilitating such operations as integration.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the AD534 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
