Brief Description
The ZMDI ZADCS1082/ZADCS1042/ZADCS1022
are 10-Bit low power analog-to-digital (A/D)
converters with up to 250ksps conversion rate.
The
approximation-register architecture.
All converters have an 8-channel input multiplexer
and a high-bandwidth a track/hold circuit. All
analog inputs are software configurable as eight /
four/two single ended or four/two/one differential
analog input channels as well as for unipolar or
bipolar output coding.
The
operate from a single +2.7V to +5.25V supply.
The
connects directly to a microcontroller using one of
the standards like SPI™, QSPI™, and Microwire™
without external components.
The ZADCS1082/ZADCS1042/ZADCS1022 use
either the external serial-interface clock or an
internally generated clock to perform successive-
approximation analog-to-digital conversions. The
internal clock
synchronous conversions on several ZMDI ADCs
in parallel.
The “V” versions ZADCS1082V/ZADCS1042V/
ZADCS1022V are equipped with a high accurate
internal 2.5V reference with an additional external
±1.5% voltage adjustment range.
The device provides a hard-wired shut-down pin
(nSHDN) and software-selectable power-down
modes to automatically shut down the IC at the
end of a conversion. Accessing the serial interface
automatically
ZADCS1042/ZADCS1022. A quick turn-on time
allows the device to be shut down between
measurements.
