n 28-Pin SSOP Package The LTC®1854/LTC1855/LTC1856 are 8-channel, low
power, 12-/14-/16-bit, 100ksps, analog-to-digital converters (ADCs). These ADCs operate from a single 5V
supply and the 8‑channel multiplexer can be programmed
for single-ended inputs, pairs of differential inputs, or
combinations of both. In addition, all channels are fault
protected to ±30V. A fault condition on any channel will not
affect the conversion result of the selected channel. n An onboard precision reference minimizes external components. Power dissipation is 40mW at 100ksps and lower
in two power shutdown modes (27.5mW in Nap mode and …
