The Texas Instruments TSC2302IRGZR is a versatile integrated circuit designed for portable devices, combining a programmable touch screen controller with a stereo audio codec. The touch screen controller offers a 4-wire resistive interface with programmable resolution up to 12 bits and sampling rates up to 125 kHz, reducing host CPU overhead. It also includes touch pressure measurement and ratiometric conversion capabilities.
The integrated stereo audio codec features a 20-bit delta-sigma ADC/DAC with a dynamic range of 98 dB and a sampling rate up to 48 kHz, transferred via an I2S interface. It supports a 16-mW stereo headphone driver, microphone input with pre-amp, and auxiliary analog inputs. The device operates from a single 2.7-V to 3.6-V supply and is housed in a 48-VQFN (7x7) package suitable for surface mounting.
Additional features include direct battery measurement up to 6 V, an on-chip temperature sensor, and full power-down control. The SPI serial interface allows for efficient communication with host controllers. This combination of functionalities makes the TSC2302 ideal for personal digital assistants, cellular phones, MP3 players, and smartphones.
