The LTC1858 is 8-channel, low power, 14-bit, 100ksps, analog-to-digital converters (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 precision reference minimize external components. The low 40mW power dissipation is made even more attractive with two user selectable power shutdown modes. DC specifications include ±1.5LSB INL for the LTC1858.
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.
