概述

Description

TMUX1104DQAR is a Texas Instruments 4-channel analog switch (TMUX family). It provides four digitally controlled analog switches that can route signals between input and output pins, enabling flexible signal multiplexing and routing in a compact, single‑supply device. Key advantages: low leakage, moderate on-resistance, bidirectional signal path, and fast switching, suitable for instrumentation, audio, sensor interfaces, and signal conditioning. The device comes in the DQAR package; exact electrical specs (supply range, on-resistance, leakage, control scheme, and temp range) are provided in the TMUX1104 datasheet.

Features

TMUX1104DQAR features (concise):
- Four independent SPST analog switches (4 channels)
- Break-before-make switching
- Single-supply operation: 1.65 V to 5.5 V (VDD range)
- Rail-to-rail analog paths; signals up to VDD
- Low on-resistance and low off-leakage (high isolation)
- Per-channel control inputs (S1–S4) with an enable to disconnect all channels
- Small 14-pin package (DQAR) suitable for compact designs
- Industrial temperature range (-40°C to 125°C)
- ESD protection on I/O pins
Note: please consult the datasheet for exact electrical specs and pinout.

Package

16-pin surface-mount TSSOP package (RoHS-compliant, DQAR variant).

Pinout

- Pin count: 14 pins (TMUX1104DQAR in a 14‑pin package).
- Function: A 4‑channel, bidirectional analog switch (four independent pass gates) with a common enable. Used to connect/disconnect four signal lines in either direction on a single-supply, low on-resistance path.

Manufacturer

Manufacturer: Texas Instruments (TI).
What kind of company: American multinational semiconductor company that designs and manufactures analog and embedded processing integrated circuits; one of the world's largest semiconductor producers, headquartered in Dallas, Texas.

Application

TMUX1104DQAR is a 4-channel analog switch/multiplexer. Common applications:
- Routing multiple analog signals to/from ADCs/DACs in data acquisition and instrumentation
- Sensor multiplexing in portable/battery-powered devices
- Audio/video signal path switching
- Signal conditioning and level shifting with isolation for multiplexed front-ends
- Test/measurement equipment for channel selection
- General-purpose analog switching where low-noise, fast, bidirectional operation is needed
