CD4052QPWRQ1 - AEC-Q100 Dual 4:1 Analog Mux | TI
MPN： CD4052QPWRQ1 ✓ 啟用中CD4052QPWRQ1 概覽
An analog multiplexer/demultiplexer is a bidirectional signal-routing device within the broader hierarchy of CMOS logic and analog switch ICs. Unlike digital-only multiplexers, the CD4052 family passes analog signals across the full supply range, with on-chip level shifting that allows logic inputs referenced to a low-voltage supply (VDD-VEE down to 3V) to control switches spanning up to 20V, making it usable in mixed-rail systems.
Key features include a wide 3V to 20V supply range, logic-level conversion via VEE, break-before-make switching, low quiescent current typical of 4000B-series CMOS, and automotive qualification per AEC-Q100. Channel on-resistance is lowest at higher VDD; TI datasheet curves show typ values on the order of 100-300 ohm depending on supply and signal level .
The 4000B CMOS process provides high noise immunity, rail-to-rail analog signal handling, and very low static power consumption, which suits battery-powered and high-voltage industrial signal chains.
Typical applications include automotive sensor signal routing, differential data acquisition front ends, audio signal selection, and industrial control multiplexing where a low-cost, high-voltage-tolerant switch is required.
Design tip: keep the INH pin tied to a defined logic level (not floating) to avoid channel glitching, and observe the VDD-VEE total limit of 20V. Prices cited as of 2026-08-29.

典型應用
CD4052QPWRQ1 適用於 6 應用s: Automotive Sensor Signal Routing, Differential Data Acquisition Front End, Audio Signal Source Selection, Industrial Control Multiplexing, Battery-Powered Portable Instrumentation, Test and Measurement Signal Switching.
Automotive Sensor Signal Routing
The CD4052QPWRQ1 routes multiple differential automotive sensors (pressure, position, temperature) into a single ADC input pair. Its AEC-Q100 qualification and -40C to +125C rating address underhood and chassis environments, while the 20V VDD-VEE span tolerates transient-rich 12V vehicle rails. Using the differential 4:1 configuration preserves signal integrity for bridge and thermocouple-type sensors, and the INH pin allows the MCU to isolate all sensors during diagnostic self-test.
推薦
Differential Data Acquisition Front End
In multi-channel data acquisition systems, the CD4052QPWRQ1 selects one of four differential signal pairs ahead of a precision ADC, reducing ADC channel count and cost. The CMOS switch architecture passes signals from VEE to VDD rail-to-rail, and logic-level conversion allows a 5V MCU to control switches running at higher analog rails. Break-before-make switching prevents momentary channel-to-channel shorts during address transitions, protecting measurement accuracy.
推薦
Audio Signal Source Selection
The CD4052QPWRQ1 selects among four stereo audio sources (differential L/R pairs) in head units and amplifiers. CMOS switches add negligible distortion at audio-band signal levels when VDD is kept high, and the absence of switching charge injection artifacts typical of smaller switches helps preserve signal purity. The VEE pin can be tied to a negative rail for AC-coupled audio designs centered at ground.
推薦
Industrial Control Multiplexing
Factory automation and process-control boards use the CD4052QPWRQ1 to share one measurement or drive path across four differential field signals. The 4000B CMOS family offers high noise immunity against industrial EMI, and the 20V supply span supports direct interface with 15V analog subsystems common in legacy industrial equipment. INH-based channel isolation simplifies safety interlocks during maintenance modes.
推薦
Battery-Powered Portable Instrumentation
With the extremely low static power draw of the 4000B CMOS process, the CD4052QPWRQ1 suits battery-powered portable meters and loggers. A low-voltage MCU can level-shift control signals to switch higher analog rails, and placing INH high fully disconnects signal paths to cut system leakage. Designers should size series resistance for the supply-dependent on-resistance to minimize gain error in the signal chain.
推薦
Test and Measurement Signal Switching
Bench instruments and automated test equipment use the CD4052QPWRQ1 to route differential test signals between measurement circuits. The wide 3V to 20V span supports multiple instrument rail standards, while break-before-make switching ensures clean channel transitions during scan sequences. Pairing the mux with a high-impedance buffer downstream minimizes the impact of the channel on-resistance on measurement accuracy.

主要差異化特點

設計說明
Never leave INH, A, or B inputs floating. Undriven CMOS control inputs on the CD4052 family can float to indeterminate levels, causing both X and Y channels to glitch or cross-conduct during transitions. In automotive designs, add 10k pull-down or pull-up resistors and route control traces away from switching noise sources. Ensure VDD-VEE never exceeds the 20V absolute maximum, including load-dump transients on 12V vehicle rails - add a series resistor and clamp if needed.
On-resistance of the CD4052 varies significantly with VDD and analog signal level, and is highest at low supply voltages. Account for Ron in gain-error budgets by keeping downstream input impedance at least 100x the worst-case Ron, or buffer the common output with a high-impedance op-amp such as the TLV2888-Q1. For differential signals, Ron mismatch between X and Y channels appears as common-mode error; matching source impedances minimizes this.
Place a 100nF ceramic decoupling capacitor directly across VDD (pin 16) and GND (pin 8). If VEE is used for negative-rail logic-level conversion, decouple VEE separately with 100nF. Keep analog signal traces short and guard the high-impedance common outputs; the break-before-make switching means the common node floats briefly during address changes, so a small hold capacitor (10-100pF) at the output can prevent transients from propagating to the ADC.
