The ATtiny1627 family of AVR® microcontrollers is equipped with high-speed integrated analog, hardware-based Core Independent Peripherals (CIPs) and low-power performance for efficient real-time control and sensor node applications. For design flexibility and to optimize your board layout, this family of 4 KB to 32 KB Flash devices is available in SOIC, SSOP and VQFN packages ranging from 14 to 24 pins. These tinyAVR® MCUs are well suited for a wide range of industrial, consumer, appliance, automotive, sensor node and other applications.

Key Features:

  • Fast and accurate signal measurement with 12-bit differential Analog-to-Digital Converter (ADC)
  • Measure small amplitude signals using the PGA
  • Improve noise suppression with built-in hardware accumulation and oversampling of up to1024 samples

  • Using high-precision architectures enables superior DC performance, regardless of operating conditions
  • Low noise and additional EMI filtering on the inputs provide additional protection in electrically noisy environments
  • Small packages, such as leadless DFNs, are ideal for space-constrained designs
  • A wide operating temperature range of –40°C to +125°C provides a robust solution even at extreme temperatures

Microchip Instrumentation Amplifier with mCAL Technology

The MCP6N11 and MCP6V2x Wheatstone Bridge Reference Design demonstrates the performance of Microchip's MCP6N11 instrumentation amplifier (INA) and a traditional three op amp INA using Microchip's MCP6V26 and MCP6V27 auto-zeroed op amps. The input signal comes from an RTD temperature sensor in a Wheatstone bridge. Real world interference is added to the bridge's output, to provide realistic performance comparisons. Data is gathered and displayed on a PC, for ease of use. The USB PIC® microcontroller and included Graphical User Interface (GUI) provides the means to configure the board and collect sample data.
