This is the Linux kernel device driver for the ADS1262, a high-precision 32-bit resolution analog-to-digital converter (ADC) from Texas Instruments. The driver facilitates interfacing with the ADS1262 ADC via the Linux kernel, allowing for efficient data acquisition from multiple channels with both single-ended and differential input modes.
- Channels: The ADS1262 provides 10 analog input channels (0-9), plus an additional common analog input pin (AINCOM).
- Modes: Supports both single-ended and differential ADC conversions, allowing for flexibility in measuring voltage differences between pairs of channels or with respect to a common ground.
- Resolution: The ADC is based on a delta-sigma architecture and offers precision data conversion up to 32-bit resolution across all input channels. This makes it suitable for high-accuracy applications such as sensor readings, industrial measurements, and scientific instrumentation.
- Interface: The ADS1262 typically communicates over SPI (Serial Peripheral Interface), which ensures fast and reliable data transfer between the ADC and the host system running Linux.
- Performance: Delta-sigma ADCs like the ADS1262 are known for their excellent noise performance and stability in long-term measurement applications, providing reliable readings even in demanding environments.
For additional details, refer to the ADS1262 datasheet.
This driver is designed to integrate the ADS1262 into the Linux kernel, providing a seamless interface to access the ADC functionality through kernel-level I/O operations. The driver supports essential features such as:
- Configuring the ADC for both single-ended and differential conversions.
- Reading data from any of the 10 input channels.
- Handling precision timing requirements for accurate data capture.
- Supports 10 input channels: Access all 10 input channels, individually or in pairs for differential readings.
- Configurable precision: Leverage the full 32-bit resolution for applications requiring high accuracy.
- SPI communication: Efficient data transfer through the SPI protocol.
