Description
General part information
LTC1856 Series
The LTC1854/LTC1855/LTC1856 are 8-channel, low power, 12-/14-/16-bit, 100ksps, analog-to-digital converters (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 on-board precision reference minimizes external components. 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.ApplicationsIndustrial Process ControlMultiplexed Data Acquisition SystemsHigh Speed Data Acquisition for PCsDigital Signal Processing
