This article introduces the performance characteristics of the LTC2366 series microcontroller ADC, including AC and DC specifications, operating voltage and current, as well as packaging and adjustable parameters.
This document addresses the limitations of built-in 8-bit and 16-bit microcontroller ADCs, which often lack sufficient AC performance. It introduces the LTC236x family as a high-performance alternative with guaranteed specifications that exceed typical on-chip solutions.
The note provides specific technical data for models including the LTC2366, LTC2365, LTC2362, LTC2361, and LTC2360. It details application circuits such as single-supply AC-coupled amplifiers using the LT6202 and programmable gain DC amplifiers using the LTC6915 to drive these ADCs effectively.
The current draw on these parts is a maximum of 4mA during a conversion.
The SPI interface requires only three wires to communicate with the microcontroller.
