time, thus preserving the relevant temporal
information of the applied signals, precisely.
This unique feature permits the
SP8530
to
ideally fit applications where the information
content is carried on dual carriers, such as
in-phase and quadrature phase systems.
Further, S

ADC architecture permits the
sampling of such signals without the necessity
of demodulating or further conditioning of the
carrier prior to conversion, potentially saving
significant amounts of other support electronics.
It is also suited to measure instantaneous
transfer functions between input signals and
their corresponding output signal.
Such measurements are commonly made in test
equipment and PIN electronics as well as in
many other systems where instantaneous cause
and effect relationships are monitored.
The
SP8530
permits the user to convert each
channel and digitally subtract the result in
external logic to produce a precise digital
differential result.
The
SP8530
is fabricated in Sipex' Bipolar
Enhanced CMOS Process that permits state-of-
the-art design using bipolar devices in the
analog/linear section and extremely low power
CMOS in digital/logic section.
CIRCUIT OPERATION
The operating circuit in Figure 1 shows a simple
circuit required to operate the
SP8530
. The
conversion is controlled by the user supplied
signal Chip Select Bar (CS) which selects and
deselects the device, and a system clock (SCLK).
A high level applied to CS asynchronously
clears the internal logic, puts the sample & hold
(CDAC) into sample mode and places the DOUT
(Data Output) pin in a high impedance state.
Conversion is initiated by falling edge on CS in
slave mode at which point the selected input
voltages are held and a conversion is started. A
delay of 90ns is required between the falling
edge of CS and the first rising of SCLK.
FEATURES
The
SP8530
is a two channel simultaneous
sampling, 12-Bit serial out data acquisition
system. The device contains a high speed 12-bit
analog to digital converter, internal reference,
and sample and hold circuitry for both channels.
The patented, simultaneous sampling feature of
this monolithic integrated circuit, permits the
user to measure and convert the analog
information on each of two channels at the same
