Product overview

The LTC1859IG is an 8-channel, 16-bit analog-to-digital converter (ADC) with a sampling rate of 100ksps and a fail-safe capability of ±25V ‌‌. Powered by a single 5V supply, the device supports a software-programmable input range of 0V to 5V, 0V to 10V, ±5V or ±10V, and can be set to a single-ended or differential input ‌. The LTC1859IG also has two outage modes with a typical power consumption of 40mW and a typical signal-to-noise ratio of 87dB‌. In addition, it uses an SPI interface, is compatible with MICROWIRE™ serial I/O, and has a nap mode and a sleep mode ‌.

LTC1859IG Key features: ‌

SoftSpan™ input range programmable ‌ : LTC1859IG supports software configuration of input voltage ranges (0-5V, 0-10V, ±5V, ±10V), compatible with single-ended or differential input modes ‌.

High reliability and protection capability ‌ : all channels are equipped with ‌±25V fault protection ‌, to ensure that the conversion accuracy is not affected ‌ when the signal is overloaded.

Low power design ‌ : typical power ‌40mW‌, LTC1859IG supports "nap mode" and "sleep mode" to further reduce energy consumption ‌.
