Analog-to-digital converters

Microchip has announced a series of low-power, high-resolution delta-Sigma analog-to-digital converters (ADCs).

The MCP3422, MCP3423 and MCP3424 (MCP3422/3/4) ADCs provide 18 bits of resolution and consume 135 µA at 3 V continuous conversion.

The multi-channel devices have an integrated voltage reference, programmable gain amplifier (PGA) and oscillator onboard. They are suitable for portable measurement applications in the industrial, medical, consumer and motor vehicle industries.

The MCP3422/3/4 ADCs’ low current consumption enables the end application to use low power, giving longer battery life. With their integrated PGA, voltage reference and oscillator, the ADCs eliminate the need for numerous external components.

The company has also released the MCP3424 evaluation board to help designers get started using the ADCs in their designs.

The board enables the user to evaluate the performance of the MCP3424 ADC by interfacing to the PICkit serial analyser.
