Intersil, Renesas offer RL78-based sensor conditioning circuit

Intersil has joined with Renesas Electronics to develop a sensor signal conditioning reference design for thermocouple, pressure and strain gauges.

The design incorporates two boards – an Intersil board with analogue front-end chips and a Renesas RL78/G13 microcontroller development board.

Renesas ups analogue spec of MCU for sensor apps

The analogue-to-digital front-end incorporates the ISL28617 40V instrumentation amplifier with integrated ADC driver, the ISL28134 5V zero drift op amp, the ISL26102 24-bit delta sigma converter and the ISL21090, an ultra low noise precision bandgap voltage reference, among others.

Software interface is included for evaluation purposes.

Powered by USB

It is powered from a debugger mini USB connection (or an optional 5V power supply) located on the Renesas RL78/G13 demonstration kit.

The +12V, +10V, and ±5V supplies on the Intersil board are generated from the 3.3V supply on the Renesas board.

The reference design is being distributed through Avnet Memec
