The TSC2300IPAGR is an integrated circuit (IC) component designed and manufactured by Texas Instruments. It is a complete analog front-end solution for capacitive touch screens and buttons. This IC offers several key features that make it ideal for various touch-sensitive applications.
One of the key features of the TSC2300IPAGR is its 12-bit SAR (successive approximation register) ADC (analog-to-digital converter). This high-resolution ADC allows for precise and accurate measurement of capacitance changes, enabling reliable touch detection and position tracking. It supports up to 12 touch channels, making it suitable for large touch screens or complex button arrays.
This IC also includes a built-in integrated charge pump to provide a stable bias voltage to drive the touch panel. The charge pump's voltage can be adjusted through external configuration to support different touch panel requirements. This flexibility allows for compatibility with a wide range of capacitive touch screens and buttons.
Furthermore, the TSC2300IPAGR incorporates a multiplexer to handle the scanning of multiple touch channels. This multiplexer can scan touch channels in a sequential or non-sequential order, offering increased flexibility in touch panel design. Additionally, it features a proximity sensing mode that can detect the presence of a hand or object without direct physical contact.
Another notable feature of the TSC2300IPAGR is its built-in digital signal processor (DSP). The DSP provides advanced algorithms for touch detection, tracking, and noise suppression
