TSC2117IRGZT

Overview

The TSC2117IRGZT is a low-power, highly integrated audio codec and touch-screen controller manufactured by Texas Instruments. It features stereo Class-D speaker amplifiers, a stereo audio DAC, a mono audio ADC, and a SAR ADC. The device supports 16-bit stereo playback and monaural recording, integrating microphone interfaces, headphone drivers, and speaker drivers. Two fully programmable miniDSPs handle digital audio processing, supporting I2S, left/right-justified, DSP, and TDM modes. It operates on a supply voltage range of 1.8 V to 3.3 V with a typical operating current of 4 mA. The component is housed in a VQFN-48 package.

Feature Summary

• Integrated stereo Class-D speaker amplifiers providing up to 1.29 W output power into an 8-ohm load.
• Embedded two fully programmable miniDSPs for digital audio processing with preprogrammed modes for bass boost, treble, or EQ.
• Smart four-wire touch-screen controller with selectable sampling rates of 250 kS/s or 192 kS/s and resolutions of 8, 10, or 12 bits.
• Supports multiple digital audio interface protocols including I2S, left/right-justified, DSP, and TDM modes.

Applications

• Handheld gaming devices
• Mobile Internet Devices (MIDs)
• Adaptive filter systems

Procurement Notes

Verify the specific suffix 'RGZT' corresponds to the VQFN-48 package and reel/cut-tape packaging format as indicated in distributor specifications. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ESD handling procedures are followed due to moisture sensitivity classification.

Selection Notes

Select this component when a combined solution for resistive touch input and high-quality audio processing is required. The TSC2117IRGZT is suitable for designs needing integrated Class-D amplification and programmable DSP capabilities within a single IC. Verify that the 1.8 V to 3.3 V supply range aligns with the system's power architecture and that the VQFN-48 footprint fits the PCB layout constraints.

Part Context

The TSC2117IRGZT belongs to the TSC2117 series from Texas Instruments. It is functionally equivalent to the TSC2117IRGZR variant, differing primarily in packaging type rather than internal circuitry. The device is part of a broader family of touch-screen controllers and audio codecs designed for portable consumer electronics requiring space-efficient, multi-functional solutions.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Designers should consult Texas Instruments for current alternative recommendations if the TSC2117IRGZT is unavailable.
