New Analog-to-Digital Converter Families

Microchip introduced a family of compact ADCs that offer high programmable data rates of up to 153.6 kilosamples per second (kSPS). The 24-bit MCP356x and 16-bit MCP346x delta-sigma ADC families offer faster programmable data rates over similar devices on the market while providing high accuracy and lower noise performance. Available in a tiny 3 mm x 3 mm UQFN-20 package, these highly integrated ADCs meet increasing demand for small packaging in space-constrained applications such as portable instrumentation devices.

Most high-resolution delta-sigma ADCs on the market have slower programmable data rates of a few kSPS. The MCP356x and MCP346x families offer a much faster data rate, making the devices ideal for a variety of precision applications that require different data speeds, including industrial process control, factory automation and sensor transducers and transmitters. The ADCs also offer integrated features to eliminate the need for external components and reduce the overall cost of a system, including an internal oscillator, temperature sensor and burnout current source.
