LTC1859IG#PBF – Analog to Digital Converter, 16 bit, 100 kSPS, Single, 4.75 V, 5.25 V, SSOP

The LTC1859IG#PBF is a 8-channel low power Analog-to-digital Converter (ADC) with shutdown. This SoftSpan™ ADCs can be software-programmed. 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. The internal clock is trimmed for 5μs maximum conversion time and the sampling rate is guaranteed at 100ksps.
