PRODUCT DESCRIPTION
PRODUCT HIGHLIGHTS
The AD 535 is a monolithic laser trimmed two-quadrant divider
having performance specifications previously found only in ex-
pensive hybrid or modular products. A maximum divider error
of :1:0.5%is guaranteed for the AD535K without any external
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).

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 ex-
ternal trims. The AD535 is the first divider to offer fully dif-
2. 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).

same time, increased reliability.
The extraordinary versatility and performance of the AD535
recommend it as the first choice in many divider and compu-
tational applications. Typical uses include square~rooting, ratio
computation "pin-cushion" correction and AGC loops as illus-
trated in the applications section of the data sheet. The device
is packaged in a hermetically sealed, 10-pin TO-100 can or 14-
pin TO-116 DIP and made available in a:1:1% max error version
(]) and a :1:0.5%max error version (K). Both versions are speci-
fied for operation over the 0 to +70oC temperature range.
