PRODUCT DESCRIPTION
The AD386 is a high accuracy, adjustment free track-and-
hold amplifier designed for high resolution data acquisition
applications. The fast acquisition time (3.6 I-I-Sto 75 j.IV. ) and
low aperture jitter (40 ps) make it ideal for u'se with fast ND
converters.
The AD386 is complete with an internal hold capacitor, and it
incorporates a compensation network which minimizes the
track-w-hold charge offset and dielectric absorption. The
AD386 also includes an internal differential amplifier for very
..15 V.
TIH
Typical applications for the AD386 include sampled data sys-
tem, peak hold function, strobe measurement system and simul-
taneous sampling converter systems. When used with autozero
and autocalibration techniques, this TIH combined with a high
linearity ND wiU offer true 16-bit performance (0.00076%
linearity) over the industrial temperature range, and 14-bit per-
high accuracy applications.
formance (0.003% linearity) over the military temperatUre range.
