DESCRIPTION
The 10-bit LTC®1850 and 12-bit LTC1851 are complete 8-channel data acquisition systems. They include a flexible 8-channel multiplexer, a 1.25Msps successive approximation analog-to-digital converter with sample-and-hold, an internal 2.5V reference and reference buffer amplifier, and a parallel output interface. The multiplexer can be configured for single-ended or differential inputs, two gain ranges and unipolar or bipolar operation.
