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.

Can be reduced down to 3 V using external resistor between –V
S
and SF.
4
Irreducible component due to nonlinearity; excludes effect of offsets.
