The working principle of the LTC2492IDE#PBF is based on a delta-sigma modulator circuit. This is an analog-to-digital converter that utilizes an integrating type analog to digital secant method. The measurement process starts with a high-gain integrator media type amplifier, where two integrators are operated in a feedback mode to amplify a differential input between the two ends of the amplifier. As the amplifiers integrate, the output voltage accumulates. The output of the integrator is fed to the modulator where the input signal is digitized by a cyclic sampling process. The data is then transmitted to the output register.

The LTC2492IDE#PBF is well suited for a variety of industrial, medical, and research applications such as thermocouple measurement, RTDs, strain gauge bridges, and other process control and automation applications. Its on-chip low-noise input stage, integrated temperature sensor, and excellent linearity make it ideal for data acquisition and measurement. Its wide operating temperature range, wide power supply range, and small 7-lead SOT23 package make it ideal for low power, space-saving applications.
