TSC2300IPAG

Overview

The TSC2300IPAG is a highly integrated analog interface circuit manufactured by Texas Instruments, designed for human interface devices. It combines a programmable resistive touch screen controller with a 20-bit stereo audio codec. The touch screen section features an SAR ADC with programmable resolutions of 8, 10, or 12 bits and sampling rates up to 125 kHz. The audio codec includes a Delta-Sigma ADC/DAC with a dynamic range of 98 dB and supports I2S interfaces at sampling rates up to 48 kHz. Operating on a single 2.7-V to 3.6-V supply, the device integrates battery monitoring, temperature sensing, and a 4x4 keypad scanner within a 64-pin TQFP package.

Feature Summary

• Integrated Touch Screen Controller: Supports 4-wire resistive screens with programmable resolution (8/10/12 bits) and sampling rates up to 125 kHz.
• Stereo Audio Codec: Features a 20-bit Delta-Sigma ADC/DAC with 98 dB dynamic range, microphone pre-amp, and stereo headphone amplifier output.
• Peripheral Monitoring: Includes dual battery voltage monitors supporting up to 6 V inputs and an on-chip temperature sensor with 0.3°C resolution.
• Keypad Interface: Built-in 4x4 keypad scanner with programmable debounce logic to reduce host CPU overhead.

Applications

• Personal Digital Assistants (PDAs)
• Cellular Phones
• MP3 Players
• Internet Appliances
• Smartphones

Procurement Notes

Verify the ordering suffix 'PAG' corresponds to the Tray transport media as specified in the datasheet. Confirm that the component meets the -40°C to +85°C operating temperature range requirements for the specific application environment. Ensure proper handling procedures are followed due to moisture sensitivity classification.

Selection Notes

Select the TSC2300IPAG when a combined solution for resistive touch input and high-fidelity audio processing is required. The device is suitable for designs needing direct battery measurement capabilities without external amplifiers. Consider the 64-pin TQFP package constraints and SPI/I2S interface compatibility with the host microcontroller during system architecture planning.

Part Context

The TSC2300 belongs to the TSC2300 series of programmable touch screen controllers with integrated audio codecs. It serves as an analog interface bridge between human input devices and digital processors. The IPAG variant specifically denotes the industrial temperature grade version housed in a standard TQFP-64 package, distinct from reel-packaged alternatives.
