What are the key features of MAX4639EUE+T?
- 3.5 Ω maximum on-resistance with ±2.5 V supply enables low-distortion analog switching in audio and sensor front-end signal paths
- Configurable as single 8:1 or dual 4:1 mux in one IC, reducing BOM and board area in multi-channel ADC front-ends
- Rail-to-rail signal range with low charge injection allows precise switching of AC and DC analog signals without baseline shift
What is MAX4639EUE+T used for?
MAX4639EUE+T is used in data-acquisition systems and portable test instruments where 4 to 8 analog sensor channels must share a single ADC input with minimal signal distortion introduced by the 3.5 Ω switch resistance. Its dual 4:1 configuration suits differential signal routing in audio codec front-ends and biomedical instrumentation amplifiers operating on ±2.5 V split supplies. The TSSOP package and low quiescent current also make it appropriate for battery-powered multichannel environmental sensor loggers requiring low-power analog multiplexing.

Frequently Asked Questions
What is the on-resistance of MAX4639EUE+T and why does it matter for ADC front-end accuracy?
MAX4639EUE+T has a maximum on-resistance of 3.5 Ω. In a 12-bit or higher ADC front-end, this switch resistance combined with input capacitance sets the RC settling time constant; at 3.5 Ω and typical 10 pF ADC input capacitance, settling to 12-bit accuracy requires approximately 100 ns, which is fast enough for ADC sampling rates up to several megasamples per second.
How can MAX4639EUE+T be configured as a dual 4:1 multiplexer in a differential measurement system?
By splitting the 8 input channels into two 4-input groups with separate enable pins, MAX4639EUE+T routes two fully independent 4:1 differential signal pairs to a dual-input instrumentation amplifier. This eliminates two separate multiplexer ICs, reducing PCB area by roughly 50% and channel-to-channel crosstalk compared to cascading single-ended muxes in differential measurement applications.
What supply voltage does MAX4639EUE+T require and which portable applications does this suit?
MAX4639EUE+T requires a dual ±2.5 V supply (±2.25 V minimum, ±2.75 V maximum), drawing low quiescent current. This supply range is compatible with single-cell Li-ion systems that use a charge-pump to generate ±2.5 V, making the device suitable for portable medical monitors, handheld environmental sensors, and battery-powered audio recorders where a split rail is available.
When is MAX4639EUE+T preferred over a higher on-resistance mux for precision sensor multiplexing?
MAX4639EUE+T's 3.5 Ω on-resistance minimises the voltage error introduced at the ADC input. For a sensor source impedance of 1 kΩ and a 16-bit ADC, the 3.5 Ω switch creates a gain error of only 0.35%, versus 3.5% for a 35 Ω mux. In precision strain-gauge, thermocouple, or pH electrode front-ends where errors below 1% are required, the low-resistance switch is essential to maintain full ADC accuracy.
