ADC from Microchip boost data rates to 153.6ksamples per second
Two analogue to digital converters (ADCs) from Microchip are claimed to offer high programmable data rates of up to 153.6ksamples per second. According to Microchip, 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.
They are supplied in a 3.0 x 3.0mm UQFN-20 package, to meet the design constraints of small packaging in portable instrumentation devices.
The MCP356x and MCP346x families offer a much faster data rate, making the devices suitable 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.
Both ADCs families provide 24-bit or 16-bit resolution, two, four or eight single-ended or one, two or four differential channel options to meet design criteria.
The MCP3564 ADC evaluation kit (ADM00583) is available now to demonstrate the performance of the MCP356x family. The kit includes the MCP3564 ADC Evaluation Board for PIC32 MCUs (ADM00583), PIC32MX795F512L PIM and USB cable.
The MCP3561 (24-bit, two-channel), MCP3562 (24-bit, four-channel), MCP3564 (24-bit, eight-channel), MCP3461 (16-bit, two-channel), MCP3462 (16-bit, four-channel) and MCP3464 (16-bit, eight-channel) are available today.
