Abstract: This paper designs a receiver circuit for an RS485 interface chip. To achieve a wide common-mode input voltage range of -7 V to 12 V, the receiver input circuit adopts a structure combining ...

The analog input of an Espressif ESP32 doesn't seem very reactive in the very first part of its allowed range, with a lack of response, and a non-linearity in the whole range, consequently. The aim of ...

Design issues for translating a DC coupled unipolar input to a differential ADC at some V cm. It is a challenging task to provide an ADC interface circuit to satisfy both the source and the ADC when ...

As the number of Power Over Ethernet (PoE) powered device (PD) applications grows, market pressures are driving designers to lower the cost and complexity of the DC-DC converters that power them, ...

Optocouplers provide high-voltage isolation between a low-voltage device like a microcontroller or a pulse-width modulation (PWM) generator and a high-voltage device like an intelligent or integrated ...
