LTC1857/LTC1858/LTC1859
8-Channel, 12-/14-/16-Bit,
100ksps SoftSpan A/D
Converters with Shutdown
FEATURES DESCRIPTION n n n n The LTC®1857/LTC1858/LTC1859 are 8-channel, low
power, 12-/14-/16-bit, 100ksps, analog-to-digital converters (ADCs). These SoftSpan^TM ADCs can be softwareprogrammed for 0V to 5V, 0V to 10V, ±5V or ±10V input
spans and operate from a single 5V supply. The 8‑channel
multiplexer can be programmed for single-ended inputs
or pairs of differential inputs or combinations of both. In
addition, all channels are fault protected to ±25V. A fault
condition on any channel will not affect the conversion
result of the selected channel. Sample Rate: 100ksps
