Analog / digital converter card
ZMD

The ZMDI ZADC1082 / ZADCS1042 / ZADCS1022 are 10-Bit low power analog-to-digital (A/D) converters with up to 250ksps conversion rate. The converter is based on successive-approximation-register architecture.
All converters have an 8-channel input multiplexer and a highbandwidth a track/hold circuit. All analog inputs are software confi gurable as eight / four / two single ended or four / two / one differential analog input channels as well as for unipolar or bipolar output coding.
The ZADCS1082/ ZADCS1042 / ZADCS1022 operate from a single +2.7V to +5.25V supply.
The synchronous four wire serial interface 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 mode can be used to run synchronous conversions on several ZMDI ADCs in parallel.
