Overview
The TSC2100IDA is a 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 and 48 kS/s with a 12-bit resolution. It operates on a supply voltage ranging from 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 resistive touch protocols.
Feature Summary
- Integrated 12-bit ADC for resistive touch screen control
- Stereo audio CODEC with integrated headphone and speaker amplifiers
- Supports multiple digital interfaces: SPI, I2S, and serial
- Programmable gain amplifier (PGA) functionality
Applications
- Portable multimedia devices requiring combined touch and audio input
- Industrial control panels with resistive touch interfaces
- Embedded systems utilizing the TSC2100EVM development kit
Procurement Notes
Verify the specific suffix 'IDA' corresponds to the TSSOP-32 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to procurement. Ensure compatibility with the required operating voltage range of 2.7 V to 3.6 V for the target application design.
Selection Notes
Select the TSC2100IDA over other variants based on the requirement for the TSSOP-32 surface-mount package. This model is suitable for designs needing both touch digitization and audio processing capabilities without separate components. Verify that the system interface supports SPI or I2S protocols as defined in the electrical specifications.
Part Context
This component belongs to the TSC2100 series of touch screen controllers. It is distinct from the TSC2100IRHB, which utilizes a VQFN-32 package. The TSC2100EVM serves as the official evaluation board for testing this device's performance and integration capabilities.
Replacement Considerations
The TSC2100IRHB is a pin-compatible alternative within the same family but differs in packaging (VQFN-32 instead of TSSOP-32). Substitution requires PCB layout verification to accommodate the different footprint dimensions.
