Microchip announces a new series of low-power, high-resolution delta-sigma analogue-to-digital Converters (ADCs). The MCP3422, MCP3423 and MCP3424 (MCP3422/3/4) ADCs provide 18-bits of resolution and consume only 135µA at 3V continuous conversion. The multi-channel devices have an integrated voltage reference, programmable gain amplifier (PGA) and oscillator onboard, eliminating the need for external components, providing a smaller overall design footprint and making it easy for designers to create smaller applications.

The converters are available at distributor Rutronik now.

They are available in packages as small as a 2 x 3mm dual flat no-lead
(DFN), and are ideal for portable measurement applications in the
industrial, medical, consumer and automotive markets, among others. Example applications for which the MCP3422/3/4 ADCs are appropriate include those in the industrial (portable weigh scales, instrumentation, handheld meters and multimeters); medical (portable heart-rate monitors, blood-pressure monitors and glucose meters); consumer (weigh scales, handheld meters); and automotive markets (sensor interfaces, fuel gauges), among others.

Microchip also announced the accompanying MCP3424 Evaluation Board (Part # MCP3424EV). The board enables the user to evaluate the performance of the MCP3424 ADC by interfacing to the PICkit™ Serial Analyzer (Part # DV164122).

With constant pressures on manufacturers to provide smaller products that
last longer on smaller batteries, low-power components available in tiny
packages are essential. The MCP3422/3/4 ADCs address these needs by not
only providing high resolution, but also multiple input channels and
integrated VREF, PGA and oscillator.
