DescripTion
The LTC
®
1854/LTC1855/LTC1856 are 8-channel, low
power, 12-/14-/16-bit, 100ksps, analog-to-digital con-
verters (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.
An onboard precision reference minimizes external com-
ponents. Power dissipation is 40mW at 100ksps and lower
in two power shutdown modes (27.5mW in Nap mode and
40µW in Sleep mode.) DC specifications include ±3LSB
INL for the LTC1856, ±1.5LSB INL for the LTC1855 and
±1LSB for the LTC1854.
The internal clock is trimmed for 5µs maximum conversion
time and the sampling rate is guaranteed at 100ksps. A
separate convert start input and data ready signal (BUSY)
ease connections to FIFOs, DSPs and microprocessors.
