Overview
The TSC2100IDAR is a programmable resistive touch screen controller manufactured by Texas Instruments, housed in a 32-pin TSSOP package. It integrates a stereo audio codec and headphone/speaker amplifier within a single device. The component supports sampling rates of 125 kS/s for touch and 48 kS/s for audio, with a 12-bit resolution. It operates on a supply voltage range of 2.7 V to 3.6 V and functions within a temperature range of -40°C to +85°C. Communication interfaces include SPI, I2S, serial, and 4-wire touch protocols.
Feature Summary
- Integrated stereo audio codec with headphone and speaker amplifiers
- Programmable resistive touch screen controller with 12-bit resolution
- Supports multiple interface protocols: SPI, I2S, Serial, and 4-Wire
- Low power consumption suitable for portable applications
Applications
- Portable media players requiring combined touch and audio functionality
- Handheld communication devices
- Industrial control panels with integrated audio feedback
Procurement Notes
Verify the suffix IDAR indicates tape-and-reel packaging distinct from the tube-packaged IDA variant. Confirm RoHS compliance status through official datasheets or manufacturer documentation prior to integration. Ensure ESD handling procedures are followed due to moisture sensitivity classification.
Selection Notes
Select this model when both resistive touch input and high-quality stereo audio output are required in a compact form factor. Compare against the TSC2100IDA if reel packaging is not needed. Consider the TSC2101 series if additional audio inputs or different pin configurations are necessary for the specific design constraints.
Part Context
This component belongs to the TSC2100 family of touch screen controllers from Texas Instruments. It shares core specifications with the TSC2100IRHB (VQFN-32 package) but differs in physical footprint. The TSC2100EVM evaluation module is available for development purposes.
Replacement Considerations
The TSC2100IDA serves as a direct functional equivalent with identical electrical characteristics but utilizes tube packaging instead of reels. For designs requiring a smaller footprint, the TSC2100IRHB offers the same functionality in a VQFN-32 package.
