Product details
Overview
MAX4582EUE+T from Maxim Integrated is a dual 4-channel CMOS analog multiplexer configured for bidirectional signal routing in low-voltage systems. It operates from ±2V to ±6V dual supplies or +2V to +12V single supply, delivers rail-to-rail analog switching, guarantees 80Ω on-resistance with ±5V supplies, and achieves < −96dB crosstalk at 50Ω. It is widely used in battery-powered audio/video routing and low-voltage data-acquisition front-ends.
For engineers reviewing the MAX4582EUE+T datasheet, MAX4582EUE+T pinout, MAX4582EUE+T application, or MAX4582EUE+T equivalent, key selection criteria include guaranteed on-resistance matching between channels, sub-1nA off-leakage at +25°C, AEC-Q100 qualification for automotive use, and compatibility with TTL/CMOS logic levels across supply ranges.
Technical Context
The MAX4582EUE+T implements two independent 4:1 analog multiplexers sharing common address inputs (A, B) and an enable control. Each multiplexer channel supports bidirectional signal flow with no ground reference-signals are bounded only by VCC and VEE rails. Its CMOS switch architecture uses charge-balanced drive circuitry to minimize charge injection (≤5pC).
It features break-before-make switching (4–20ns), fast address transition times (90–200ns), and guaranteed performance over −40°C to +85°C. The device maintains low distortion (<0.02% THD at 600Ω) and high off-isolation (<−74dB at 50Ω), making it suitable for precision signal-path selection where leakage, crosstalk, and flatness matter.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | ±2V to ±6V dual or +2V to +12V single - enables operation in both bipolar sensor interfaces and single-supply portable systems. |
| On-Resistance (RON) | 80Ω max with ±5V supplies - ensures minimal signal attenuation and gain error in 50Ω–600Ω impedance applications. |
| Off-Leakage Current | 1nA max at +25°C - preserves accuracy in high-impedance sampling circuits and battery-monitoring paths. |
| Crosstalk | <−96dB at 50Ω, 1MHz - prevents interference between active and inactive channels in multi-signal routing. |
| THD | <0.02% at 600Ω, 20Hz–20kHz - maintains fidelity in audio and instrumentation signal chains. |
| Logic Compatibility | TTL/CMOS thresholds (0.8V/2.4V at +5V) - eliminates need for level-shifting when interfacing with microcontrollers or FPGAs. |

Pinout & Package
MAX4582EUE+T is housed in a 16-pin TSSOP package (JEDEC MO-153, 4.4mm × 5.0mm × 1.2mm) with exposed pad connected to VCC per datasheet recommendation.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | X2 | Analog input channel 2 for X-multiplexer - interchangeable as input or output; rail-to-rail capable. |
| 2 | X1 | Analog input channel 1 for X-multiplexer - shares same electrical characteristics and leakage specs as X0–X3. |
| 3 | X | X-multiplexer common output - bidirectional node; connects to selected X0–X3 channel when enabled. |
| 4 | X0 | Analog input channel 0 for X-multiplexer - lowest-addressed channel; identical RON and flatness spec. |
| 5 | X3 | Analog input channel 3 for X-multiplexer - highest-addressed X channel; matches timing and leakage of others. |
| 6 | A | Address bit A - LSB of 2-bit binary select for both X and Y multiplexers; TTL/CMOS compatible. |
| 7 | B | Address bit B - MSB of 2-bit binary select; jointly controls channel selection across both mux sections. |
| 8 | GND | Digital ground reference - separate from analog signal path; no analog current flows to GND. |
| 9 | VEE | Negative supply - tied to GND for single-supply operation; sets lower rail for analog signal swing. |
| 10 | VCC | Positive supply - powers internal logic and analog switches; exposed pad must connect to VCC. |
| 11 | Y0 | Analog input channel 0 for Y-multiplexer - electrically isolated from X section; independent RON match. |
| 12 | Y2 | Analog input channel 2 for Y-multiplexer - supports simultaneous routing of two independent 4:1 signal streams. |
| 13 | Y | Y-multiplexer common output - fully independent of X output; enables dual-path signal management. |
| 14 | Y1 | Analog input channel 1 for Y-multiplexer - shares same leakage, distortion, and bandwidth specs as Y0/Y2/Y3. |
| 15 | Y3 | Analog input channel 3 for Y-multiplexer - completes 4-channel set; all Y inputs exhibit matched ∆RON ≤10Ω. |
| 16 | ENABLE | Active-high enable - disables both multiplexers simultaneously; reduces supply current to <1µA when low. |

FAQ
What is the maximum analog signal voltage range supported by the MAX4582EUE+T?
The MAX4582EUE+T supports rail-to-rail analog signals from VEE to VCC. With ±5V dual supplies, this yields a full −5V to +5V range; with +5V single supply (VEE = GND), the range is 0V to +5V. Absolute maximum ratings limit VCC–VEE to 13V, and individual pin voltages must stay within (VEE − 0.3V) to (VCC + 0.3V). Exceeding these risks ESD diode conduction and potential damage.
Does the MAX4582EUE+T require external pull-up or pull-down resistors on its address or enable pins?
No, the MAX4582EUE+T does not require external biasing on A, B, or ENABLE pins. Its digital inputs have guaranteed TTL/CMOS-compatible thresholds (0.8V low, 2.4V high at +5V), and input leakage is ±1µA max. Direct connection to microcontroller GPIOs or FPGA outputs is sufficient. Pull-ups are only needed if the driving source cannot actively drive both logic states.
Can the MAX4582EUE+T be used with a +3.3V single supply, and what impact does that have on performance?
Yes, the MAX4582EUE+T operates with +3.3V single supply (VEE = GND). At +3.3V, typical on-resistance rises to ~150Ω (vs. 80Ω at ±5V), and switching times increase (e.g., tTRANS up to 300ns). Off-leakage remains ≤5nA at +85°C, and THD stays <0.02% - making it viable for low-power, moderate-bandwidth applications like portable medical sensors or IoT node front-ends.
How is channel crosstalk measured for the MAX4582EUE+T, and what does <−96dB mean in practice?
Crosstalk for the MAX4582EUE+T is measured per Figure 6 in the datasheet: a 1MHz, 50Ω signal is applied to one active channel while adjacent channels are terminated in 50Ω, and coupled energy into those off-channels is quantified. <−96dB means the interfering signal is attenuated by >1 million times - critical for preserving SNR in multi-channel audio mixers or simultaneous-sampling data loggers where channel independence is essential.
Is the exposed pad on the MAX4582EUE+T's TSSOP package required to be soldered, and how should it be connected?
Yes, the exposed pad on the MAX4582EUE+T's TSSOP package must be soldered to PCB copper for thermal and electrical integrity. Per Maxim's datasheet (page 15), it must be connected directly to VCC - not GND or floating. This improves thermal dissipation and reduces noise coupling. A minimum of 4 thermal vias to an internal VCC plane is recommended for reliable operation at full temperature range.
