The MCP356x 24-bit and MCP346x 16-bit delta-sigma A/D converter families offer higher programmable data rates than other similar devices on the market, along with high accuracy and lower noise. These highly integrated A/D converters, supplied in tiny 3 mm x 3 mm UQFN-20 packages, meet the growing demand for small packages in space-constrained applications such as portable instruments.
High-resolution delta-sigma A/D converters on the market typically have slower programmable data rates, on the order of a few kSPS. The MCP356x and MCP346x families offer significantly higher rates, making these devices ideal for a variety of precision applications that demand different data rates, such as industrial process control, industrial automation, sensor transducers, and transmitters. These A/D converters also integrate features to eliminate the need for external components and reduce the overall system cost, including an internal oscillator, a temperature sensor, and a diagnostic current source.
The new families offer 24-bit or 16-bit resolution, two/four/eight single-terminated channels, or one/two/four differential channels, allowing developers to choose the most suitable A/D converter for their designs. These devices join Microchip's extensive portfolio of versatile A/D converters, covering a wide range of requirements in terms of speed, accuracy, and power consumption.
The MCP3564 A/D converter evaluation kit (ADM00583) is now available to demonstrate the capabilities of the MCP356x family. The kit includes the following components:
• MCP3564 A/D converter evaluation board for PIC32 microcontrollers (ADM00583)
• PIC32MX795F512L PIM
• USB cable
The MCP356x and MCP346x A/D converters are now available and are supplied in 3 mm x 3 mm UQFN-20 packages.
