Overview
The LTC1859CG#TRPBF is an 8-channel, 16-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is part of the SoftSpan™ family, known for its low power consumption and high precision. It operates from a single 5V supply and can be software-programmed for various input spans, including 0V to 5V, 0V to 10V, ±5V, or ±10V. The ADC features an onboard high-performance sample-and-hold circuit and a precision reference, minimizing the need for external components. With its low power dissipation of 40mW and two user-selectable power shutdown modes, this ADC is ideal for applications requiring high accuracy and low power consumption.
