DESCRIPTION
The ISO102 and ISO106 isolation buffer amplifiers
are two members of our series of capacitive coupled
isolation products from Burr-Brown. They have the
same electrical performance and they differ in accu-
racy. The ISO102 is rated for 1500Vrms in a 24-pin
DIP. The ISO106 is rated for 3500Vrms in a 40-pin
DIP. Both side-brazed DIPs are 600mil wide and have
industry standard package dimensions with the excep-
tion of missing pins between input and output stages.
This permits utilization of automatic insertion tech-
niques in production. The three-chip hybrid with its
generous high voltage spacing is easy to use (no
external components are required).
Each buffer accurately isolates ±10V analog signals
by digitally encoding the input voltage and uniquely
coupling across a differential ceramic capacitive bar-

rier. All elements necessary for operation are con-
tained within the DIP. This provides compact signal
isolation in a hermetic package.

NOTES: (1) 100% tested at rated continuous for one minute. (2) Isolation-mode rejection is the ratio of the change in output voltage to a change in isolation barrier voltage.
It is a function of frequency as shown in the Typical Performance Curves. This is specified for barrier voltage slew rates not exceeding 100V/µs. (3) Adjustable to zero.
FSR = Full Scale Range = 20V. (4) Nonlinearity is the peak deviation of the output voltage from the best fit straight line. It is expressed as the ratio of deviation to FSR.
(5) Power supply rejection = change in VOS/20V supply change. (6) Ripple is the residual component of the barrier carrier frequency generated internally. (7) Dynamic
range = FSR/(voltage spectral noise density x square root of user bandwidth). (8) Overshoot can be eliminated by band-limiting. (9) See “Power Dissipation vs
Temperature” performance curve for limitations. (10) Band limited to 10Hz, bypass capacitors located less than 0.25" from supply pins.
