概述

Description

FDC1004QDGSRQ1 is a Texas Instruments 4-channel capacitive-to-digital converter (CDC) with an I2C interface. It monitors capacitance changes on four independent sensing channels (CH0–CH3) and converts them to digital values for touch, proximity, or non-contact sensing. Key features include shield drive to reduce parasitic capacitance, programmable acquisition timing and sensitivity, automatic calibration/offset compensation, and a data-ready/interrupt option. It supports single-shot or continuous measurement modes, low-power operation, and a 2.7–5.5 V supply. The QDGSRQ1 suffix denotes a specific TI package/reel variant of the part. Typical applications: capacitive touch buttons and sliders, proximity sensing, and non-contact level sensing in consumer and embedded devices.

Features

Here are the key features of the FDC1004QDGSRQ1:
- 4-channel capacitive-to-digital converter (C2D) for touch/sense
- I2C interface (fast-mode compatible)
- Independent shield driver to minimize parasitic capacitance
- Auto-calibration and offset/calibration options
- Programmable measurement range and resolution for capacitive sensing
- Low-power operation with standby/single-shot modes
- Flexible drive/reference options; does not require external high-precision reference
- Wide supply range (typical 1.8V–3.6V) and industrial-grade temperature range
- Status/interrupt outputs for data-ready or fault signaling
- Small 16-pin QFN package (QDGSRQ1 variant), RoHS-compliant
Note: exact electrical specs (e.g., data rate, resolution, full-scale capacitance) are device- and configuration-dependent; consult the datasheet for precise numbers.

Package

FDC1004QDGSRQ1 uses a QFN-16 (Quad Flat No-Lead) package, typically 3 mm × 3 mm with 16 pins.

Pinout

- Pin count: 16 pins (QFN package).
- Function: Four-channel capacitive-to-digital converter with I2C interface. It provides CH1–CH4 sense inputs for electrodes, I2C bus (SDA, SCL) for control and data, VDD and GND power pins, an address-select pin for I2C addressing, and pins for reset/shutdown and an interrupt/alert output.

Manufacturer

- Manufacturer: Texas Instruments Incorporated (TI).
- What kind of company: An American multinational semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing integrated circuits.

Application

- Four-channel capacitive touch sensing (buttons, sliders, wheels)
- Proximity/presence detection and basic gesture sensing
- Liquid-level and dielectric sensing (fluids, packaging)
- Displacement/position sensing with capacitive sensors
- Applications in consumer electronics, wearables, home appliances
- Industrial and automotive control systems needing non-contact sensing
