The TSC2301 is a highly integrated PDA analog interface circuit. It contains a complete 12-bit A/D resistive touch screen converter (ADC) including drivers, touch pressure measurement capability, keypad controller, and 8-bit D/A converter (DAC) output for LCD contrast control. The TSC2301 offers programmable resolution of 8, 10, and 12 bits and sampling rates up to 125 kHz to accommodate different screen sizes. The TSC2301 interfaces to the host controller through a standard SPI serial interface.

The TSC2301 features a high-performance 20-bit, 48-ksps stereo audio codec with highly integrated analog functionality. The audio portion of the TSC2301 contains microphone input with built-in pre-amp and microphone bias circuit, an auxiliary stereo analog input, a stereo line-level output, a differential mono line-level output, and a stereo headphone amplifier output. The digital audio data is transferred through a standard I²S interface. A fully programmable PLL for generating audio clocks from a wide variety of system clocks is also included.

The TSC2301 also offers two battery measurement inputs capable of battery voltages up to 6 V, while operating at a supply voltage of only 2.7 V. It also has an on-chip temperature sensor capable of reading 0.3°C resolution. The TSC2301 is available in 64-lead TQFP, and 120-ball VFBGA packages.

COEFFICIENT-CALC — Coefficient Calculator For Digital Biquad Filters

COEFFICIENT-CALC (TIBQ) calculates the coefficients for the digital filter biquad transfer function implemented in TI audio codecs. The characteristics of the digital filter are adjusted by selecting a filter type and moving a control point within a window that shows the transfer function gain and (...)
