详细介绍

The ZMD ZADCS1282/ ZADCS1242 / ZADCS1222 are 12-Bit low power analog-to-digital (A/D) converters with up to 200ksps 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.

TheZADCS1282/ ZADCS1242 / ZADCS1222 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 ZADCS1282/ ZADCS1242 / ZADCS1222 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 ZMD ADCs in parallel.



The “V” versions ZADCS1282V/ ZADCS1242V / ZADCS1222V 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 powers up the ZADCS1282/ ZADCS1242 / ZADCS1222 . A quick turn-on time allows the device to be shut down between measurements.
