The AD 535 is a monolithic laser trimmed two-quadrant divider
having performance specifications previously found
only in expensive hybrid or modular products.
A maximum divider error of :1:0.5%is guaranteed for the AD535K
without any external trimming over a denominator
range of 10: 1, :1:2.0%max error over a range of 50: 1. A
maximum error of :1:1 over the 50: 1 % denominator range is guaranteed
with the addition of two external trims.
The AD535 is the first divider 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; by means of an external resistor,
this can be reduced by any amount down to 3.
PRODUCT HIGHLIGHTS 1.
Laser trimming at the wafer stage enables
the AD5 35 to provide high accuracies without
the addition of external trims (:to.5% max error
over a 10:1 denominator range for the AD535K).
Improved accuracies over a wider denominator
range are possible with only two external trims (:1:0.5%max
error over a 20:1 denominator range for the AD535K).
Differential inputs on the X, Yand Z input terminals
enhance the AD5 35's versatility as a generalized
analog computational circuit.
Monolithic construction permits low cost and,
at the same time, increased reliability.
