DESCRIPTION
The
LTC
®
1857/LTC1858/LTC1859
are 8-channel, low
power, 12-/14-/16-bit, 100ksps, analog-to-digital convert-
ers (ADCs). These SoftSpan™ ADCs can be software-
programmed 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.
An onboard high performance sample-and-hold and pre-
cision reference minimize external components. The low
40mW power dissipation is made even more attractive with
two user selectable power shutdown modes. DC specifica-
tions include ±3LSB INL for the LTC1859, ±1.5LSB INL
for the LTC1858 and ±1LSB for the LTC1857.
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.
