Overview

Description

ADS7841E/2K5 are Analog Devices’ 4‑wire resistive touch screen controllers. They combine a 12‑bit ADC and the front end needed to read a resistive touch panel, plus a simple SPI‑like serial interface to the host microcontroller. They automatically scan X and Y coordinates and sense touch pressure (Z), delivering 0–4095 digital codes for X and Y. They operate from a single supply (typical 2.7–5.25 V) and come in variants for extended temperature (E) or the 2.5 V reference/version family (2K5). Features often include PENIRQ for touch detect and low power operation. Typical use: embedded HMIs, handhelds, medical/industrial panels with resistive touch screens.

Features

Here are concise features of the ADS7841E/2K5:
- 12-bit analog-to-digital conversion
- SPI-compatible serial interface, up to 2.5 MHz
- Suitable for resistive touchscreen input (X+, X−, Y+, Y−)
- Single-supply operation: 2.7 V to 5.25 V
- Low-power operation with standby/idle modes
- Small package suitable for compact, low-cost designs
- 0 to Vref input range with digital output data ready via DOUT/CS
Note: Exact timing, input ranges, and package options are specified in the datasheet.

Package

ADS7841E/2K5 is available in a 16-pin plastic SOIC (surface-mount) package.

Pinout

- Pin count: 8 pins (8-pin package)
- Function: TI ADS7841E/2K5 is an 8-pin, SPI-like touchscreen analog-to-digital converter. It drives and reads a resistive touch screen to yield X and Y coordinate data (12-bit in typical use). The 2K5 suffix denotes a variant with an internal 2.5 V reference and related options; pins include power (VCC, GND) and the SPI interface (CS, SCLK, DIN, DOUT) plus the analog input paths for the touch-screen signals.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: A global American semiconductor company that designs and manufactures analog and mixed-signal integrated circuits (including data converters, op-amps, power management, microcontrollers) and serves electronics manufacturers worldwide.

Application

Application areas:
- Interface for resistive touch screens (4/8‑wire) in handhelds and consumer electronics
- Human–machine interfaces in POS terminals, kiosks, and industrial control panels
- Instrumentation and medical devices
- Automotive dashboards/infotainment
- General low‑power touch sensing for appliances and similar devices

Equivalent

Equivalent products (4‑wire touchscreen A/Ds with SPI interface):
- TI TSC2046
- TI TSC2000/TSC2003 family
- Sitronix XPT2046
Note: These are common drop-in style substitutes; verify exact pinout, timing, and resolution in datasheets before replacing.
