GENERAL DESCRIPTIO~
The A0206 is a high speed. m'o-port. tran,tl
m<:r-(l\upied i,u[atien amplifier expressly deslgm:d for applic;!uons [hat require
the amplification and isolation 01 extremeh' fa~t analog signals,
The innovati,'e circuit and translormer design of the .-6 ensures the wideband dynamic characteristics uf the .-6 while
preser\'ing the key dc perlormance spcciticatlons,
Flexible Input and Buffered Output Stages: An uncommitted
<'amp is provided on the inpUt stage 01 the A0206, This allows for inpUt buffering and gain as needed. The .-6 also
teatUres a buffered oUtpUt stage, allowing it to drive low imped,!r'.celoads.
TE
High Accuracy: Exhibiting a typical nonlinearity of =0.005%
B grade' of full-scale range and a total harmonic distortion of
- 80 dB I typical ((l 1 kHz), the .-6 provides high isolation
\'ithoUt loss of signal integrity and quality,
Excellent Common-Mode Performance: The A0206BY
.-6:\Y prO\'ides 1.5 kV rms ,0.75 k" rms)
of commonmode protection. Both grades featUre a low common-mode ca\!\'\;
1citance of \~,5 pF, inclusive of power isolation, resulting in a
t\'pical common-mode rejection specitication of 10S dB
(l k\!1
source impedance imbalance) as well as a low leakage current of
2.0 I.I.ArIDSlmax ({( 240 V rms, 60 Hz;.
The A0206 prondes total gah'anic isolation between the inpUt
and output stages 01 the isolation amplitier, including the p\\'er
,>upplies. through [he use of internal transturmer (()upiing, The
functionally complete design 01 the .-6. p<)\wed b,' a bipolar = 15 \' dc supply. diminates the need lor a u,cr supplied
isolated dc/dc con"erter. This permits the designer to minimize
the necessary circuit overhead and consequentl\' reduce the o"erall system design and component costs,
The design of the A0206 emphasizes maximum t1exibilin' and
ease of use in a broad range 01 applications where rapidly "arying analog signals must be measured and transmitted under high
c.\IV conditions, The A0206 has a = 10 \' input/output range.
a specified gain range of 1 to 10. a buffered output and a fromend power supply of :: 15 \' de with = 10 mA of current dri,'e
capability.
Isolated Power: An unregulated isolated = 15 V dc power supply with = 10 mA of current drive capabilitv is available at the
inpUt port of the A0206. This permits the isolatOr to power up
tloating signal conditioners, front-end amplifiers or remo~e
transducers at the input.
Performance Rated over the -40°C to +S5°C TemplCrature
Range: With an extended industrial temperatUre range rating,
the A0206 is an ideal isolation amplifier for use in industrial
em'ironmems.
