ADS7846IGQCR

Overview

The ADS7846IGQCR is a resistive touch screen controller manufactured by Texas Instruments, belonging to the ADS7846 series. It features a 12-bit resolution and supports a sampling rate of 125 kS/s. The device operates on a supply voltage range of 2.2 V to 5.25 V with a typical operating current of 280 uA. Communication is handled via a serial 3-wire SPI interface. It is housed in a BGA-Microstar-Junior-48 package suitable for surface mount installation. The component functions within a temperature range of -40°C to +85°C.

Feature Summary

12-bit resolution with 125 kS/s sampling rate
Serial 3-Wire SPI interface compatibility
Low power consumption at 280 uA operating current
Wide supply voltage support from 2.2 V to 5.25 V

Applications

Resistive touch screen control systems
Portable electronic devices requiring low power interfaces
Industrial control panels with resistive input requirements

Procurement Notes

The ADS7846IGQCR is listed as End-of-Life (EOL) by Texas Instruments. Distribution availability is restricted, with some sources indicating no sales in certain regions. Verification of current stock status and alternative sourcing strategies is recommended due to discontinuation status.

Selection Notes

Select this component for applications requiring a dedicated resistive touch controller with SPI connectivity. Ensure the design accommodates the BGA-Microstar-Junior-48 package constraints. Verify that the system voltage aligns with the 2.2 V to 5.25 V operational range and that the EOL status does not conflict with long-term production requirements.

Part Context

This part is a specific package variant of the ADS7846 family, distinguished by its BGA-Microstar-Junior-48 form factor. Other variants in the series include SSOP-16 and TSSOP-16 packages, such as the ADS7846E and ADS7846N/2K5, which share identical electrical specifications but differ in physical footprint and pinout configuration.

Replacement Considerations

Direct substitutes include other ADS7846 package variants like ADS7846EG4 or ADS7846IRGVT, provided the PCB layout supports the respective package type. Cross-referencing with the ADS7843 or ADS7845 may be necessary if pin compatibility differs.
