CAP1298-1 in CAP12xx Touch Controllers Family
The CAP1298-1 is a multi-channel capacitive touch controller family manufactured by Microchip Technology. It features eight independent capacitive touch sensor inputs with integrated proximity detection and signal processing. Designed for low-power operation, it utilizes a standard I2C/SMBus interface to communicate with a host microcontroller. The family is primarily used for implementing touch-sensitive buttons, sliders, and proximity sensors in user interfaces where high sensitivity and EMI robustness are critical for reliable operation.
Variants in This Sub-Family
The variants within the CAP1298-1 sub-family, such as the CAP1298-1-SL and CAP1298-1-SL-TR, represent identical silicon and electrical specifications. The primary distinction lies in the delivery format and packaging. The SL suffix denotes the 14-pin SOIC package provided in standard tubes, whereas the SL-TR suffix specifies the same SOIC package delivered on Tape and Reel for high-volume automated assembly lines.
