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.
“Accuracy is often sacrificed in ADCs that offer high resolution and faster data rates,” said Bryan J. Liddiard, vice president of Microchip’s mixed-signal and linear business unit. “These devices offer much faster programmable speeds while maintaining the high accuracy that precision applications depend on.”
The new families provide 24-bit or 16-bit resolution, two/four/eight single-ended or one/two/four differential channel options, allowing developers to choose the most suitable ADC for their designs. The devices join Microchip’s extensive portfolio of versatile ADCs that meet the needs of a variety of speed, accuracy and power consumption requirements.
The MCP3564 ADC evaluation kit (ADM00583) is available to demonstrate the performance of the MCP356x family. The kit includes the following components:
- MCP3564 ADC Evaluation Board for PIC32 MCUs (ADM00583)
- PIC32MX795F512L PIM
- USB Cable
