TSC2300IPAGR

Overview

The TSC2300IPAGR is a programmable touch screen controller with an integrated audio codec, manufactured by Texas Instruments. It features a 12-bit SAR ADC for resistive touch screens with sampling rates up to 125 kHz and a 20-bit delta-sigma audio codec supporting 48 kHz sampling. The device operates on a single 2.7 V to 3.6 V supply and communicates via SPI and I2S interfaces. It includes battery monitoring, temperature sensing, and a 4x4 keypad interface in a 64-pin TQFP package.

Feature Summary

• Integrated 12-bit SAR ADC with programmable resolution (8/10/12 bits) and sampling rates up to 125 kHz
• 20-bit delta-sigma audio codec with 98 dB dynamic range and 48 kHz sampling rate
• Built-in microphone pre-amplifier, stereo headphone amplifier, and mono line output
• Supports 4-wire resistive touch screens, 4x4 keypads, and dual battery voltage monitoring

Applications

• Personal Digital Assistants (PDAs)
• Cellular phones and smartphones
• MP3 players and internet appliances

Procurement Notes

Verify the 'R' suffix indicates tape and reel packaging as specified in the ordering information. Confirm the 'I' designation corresponds to the industrial temperature range of -40°C to +85°C. Ensure the host system supports both SPI for control and I2S for audio data transfer.

Selection Notes

Select this component when a combined touch input and high-fidelity audio solution is required in a single IC. It is suitable for designs needing direct battery measurement up to 6V while operating at low supply voltages. Consider the 64-pin TQFP footprint for PCB layout constraints.

Part Context
