- Logic-level translation allows CMOS or TTL digital control while switching analog signals up to ±10 V
- AEC-Q100 automotive-grade qualification for reliable operation in -40°C to +125°C vehicle environments
Applications
CD4051BQPWRQ1 is used in automotive body control modules and sensor acquisition systems to multiplex up to 8 analog inputs, such as temperature, pressure, or position sensor outputs, into a single ADC channel. Its ±10 V analog signal range and 20 MHz bandwidth make it suitable for audio signal switching in infotainment head units as well. The 16-pin SOIC package fits compact PCB layouts in ADAS sensor interface boards where channel density and automotive qualification are both required.

Frequently Asked Questions
How many analog channels does CD4051BQPWRQ1 switch and what is the analog bandwidth?
CD4051BQPWRQ1 is an 8:1 single-ended analog multiplexer with a nominal analog bandwidth of 20 MHz. Three binary address inputs select 1 of 8 channels, routing signals between -0.5 V and 20.5 V on the supply rails. This bandwidth is sufficient for audio frequency signals up to 20 kHz and moderate-speed sensor data acquisition at sample rates up to several megasamples per second.
Can CD4051BQPWRQ1 handle bipolar analog signals from a ±5 V sensor output?
Yes, CD4051BQPWRQ1 supports a negative supply voltage down to -10 V on the VSS pin, allowing bipolar analog signal ranges of up to ±10 V when VDD is +10 V and VSS is -10 V. A ±5 V sensor output sits well within this window. The logic control inputs still operate at standard 3.3 V or 5 V CMOS levels because the built-in logic-level conversion circuit translates digital control voltages independently from the analog supply range.
In an 8-sensor automotive acquisition board, what on-resistance does the selected channel contribute to measurement error?
CD4051BQPWRQ1's channel on-resistance is typically around 80 Ω to 200 Ω at 5 V supply, depending on signal voltage within the ±10 V range. For a 12-bit ADC with 10 kΩ input impedance, the 200 Ω switch resistance creates less than 2% gain error per channel, which is acceptable for temperature or pressure sensor readings in -40°C to +125°C automotive operating conditions. Using a buffer amplifier before the mux input reduces this error to negligible levels.
