LTC1852/LTC1853
8-Channel, 10-Bit/12-Bit,
400ksps, Low Power, Sampling ADCs
FEATURES DESCRIPTION n The 10-bit LTC®1852 and 12-bit LTC1853 are complete
8-channel data acquisition systems. They include a flexible
8-channel multiplexer, a 400ksps successive approximation analog-to-digital converter, an internal reference and a
parallel output interface. The multiplexer can be configured
for single-ended or differential inputs, two gain ranges and
unipolar or bipolar operation. The ADCs have a scan mode
that will repeatedly cycle through all 8 multiplexer channels
and can also be programmed to sequence through up to
16 addresses and configurations. The sequence can also
be read back from internal memory. n Flexible 8-Channel Multiplexer
