功能描述

The LTC1854/LTC1855 are 8-channel, low power, 12-/14-bit, 100ksps, analog-to-digital converters (ADCs). These ADCs operate from a single 5V supply and the 8-channel multiplexer can be programmed for singleended inputs or 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 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 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.
