Product details
Overview
MAX4692ETE+ from Maxim Integrated is a dual 4-channel analog multiplexer configured as two independent 4:1 muxes in a 16-pin TQFN-EP package. It operates from single +2V to +11V or dual ±2V to ±5.5V supplies, delivers ≤35Ω on-resistance at +5V, guarantees ≤3Ω channel-to-channel RON match, and supports rail-to-rail signal switching for audio/video routing in battery-powered cellular phones and communications circuits.
For engineers reviewing the MAX4692ETE+ datasheet, MAX4692ETE+ pinout, MAX4692ETE+ application, or MAX4692ETE+ equivalent, this page provides verified electrical specifications, functional pin mapping, real-world use scenarios, and validated alternative parts for dual 4:1 analog multiplexer selection in low-voltage, space-constrained designs.
Technical Context
The MAX4692ETE+ implements two independent CMOS analog multiplexers sharing address inputs A and B, enabling simultaneous selection of one of four inputs per channel (X0–X3 and Y0–Y3) to their respective common outputs X and Y. Its internal logic-level translators support 1.8V-compatible digital control at +3V supply and TTL compatibility at +5V.
It features guaranteed break-before-make switching (tBBM ≤ 2ns), rail-to-rail analog signal handling across V+ to V−, and low dynamic parameters: tON = 45ns (typ), tOFF = 100ns (typ) at +5V with 300Ω/35pF load, and −87dB crosstalk at 100kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | Dual independent 4:1 analog multiplexer (X and Y channels) |
| Supply Range | +2V to +11V single supply; ±2V to ±5.5V dual supply (MAX4692 supports both) |
| On-Resistance (RON) | ≤35Ω max at +5V supply - ensures minimal signal attenuation and voltage drop in precision analog paths |
| RON Match | ≤3Ω max at ±4.5V - maintains consistent gain/attenuation across selected channels |
| Leakage Current | ±20nA max at +85°C - preserves DC accuracy in high-impedance sensor or bias networks |
| Switching Speed | tON = 45ns / tOFF = 100ns typ at +5V - supports audio-band and medium-speed data acquisition |
| Crosstalk | −87dB at 100kHz - prevents interference between active and inactive signal paths |
Pinout & Package
MAX4692ETE+ uses a 16-pin TQFN-EP (4mm × 4mm, exposed pad) package. The exposed pad (EP) must be soldered to V+ for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 4, 12, 11, 9, 8 | X0–X3, Y0–Y3 | Analog inputs for each 4:1 mux channel - bidirectional, rail-to-rail capable |
| 13, 15 | X, Y | Common analog outputs - connect to downstream signal chain (e.g., ADC input or amplifier) |
| 5, 7 | A, B | Digital address inputs - jointly select one of four inputs per mux (00→X0/Y0, 11→X3/Y3) |
| 14 | V− | Negative analog supply - tie to GND for single-supply operation; required for dual-supply mode |
| 2 | GND | Digital ground reference - separate from analog signal path; no analog ground reference |
| 10 | EN | Enable input - logic high disables all switches; normally tied to GND for active operation |
| 6 | V+ | Positive analog/digital supply - powers internal logic and switch transistors; connects to EP |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed break-before-make | Ensures no momentary short between input channels during switching - critical for avoiding signal glitches in shared-bus systems |
| Rail-to-rail signal handling | Supports analog signals from V− to V+ - enables full dynamic range utilization without level-shifting in ±5V or single +5V systems |
| 1.8V logic compatibility | Accepts 1.8V logic thresholds at +3V supply - simplifies interface with modern low-voltage microcontrollers and FPGAs |
| Low 1nA leakage current | Maintains signal integrity in high-Z applications such as medical sensor front-ends or precision voltage references |
| −88dB off-isolation | Minimizes feedthrough from unselected channels - essential for multi-source audio mixing and test equipment signal routing |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 4:1 analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4692EBE+T | Same functionality and specs, but in 16-bump UCSP (2mm × 2mm); no exposed pad; requires specialized assembly | Better suited for ultra-compact PCBs where board area is constrained more than thermal budget | Select when minimizing footprint is critical and assembly process supports UCSP reliability requirements |
| ADG732BRUZ | 32-channel single-ended mux; higher channel count but larger 32-TSSOP package; RON = 4Ω typical at +5V; no dual-supply support | Designed for high-channel-count, single-supply industrial I/O modules - not pin-compatible or functionally identical | Choose only when scaling beyond two 4:1 paths is needed and dual-supply operation is unnecessary |
Compared with MAX4692EBE+T, the MAX4692ETE+ offers superior thermal dissipation via its exposed pad and standard TQFN reflow compatibility; compared with ADG732BRUZ, it provides true dual-supply capability and smaller footprint per mux pair, making it optimal for portable dual-rail signal routing.

FAQ
What is the maximum supply voltage rating for MAX4692ETE+?
The MAX4692ETE+ supports absolute maximum ratings of V+ to GND = −0.3V to +12V and V+ to V− = −0.3V to +12V. For reliable operation, use within the recommended ranges: single supply +2V to +11V or dual supply ±2V to ±5.5V. Exceeding these limits risks permanent damage, especially if analog signals exceed V+ or V− by more than 0.3V.
Does MAX4692ETE+ support dual-supply operation?
Yes, MAX4692ETE+ supports dual-supply operation from ±2V to ±5.5V. In this mode, V− must be connected to a negative rail (not GND), enabling true bipolar signal handling from V− to V+. The device guarantees 25Ω max RON, 3.5Ω max RON flatness, and 3Ω max channel matching under ±4.5V conditions - critical for precision AC-coupled applications.
What is the function of the EN pin on MAX4692ETE+?
The EN (Enable) pin on MAX4692ETE+ is an active-high digital control input. When driven logic high, it disables both 4:1 multiplexers - opening all internal switches regardless of address inputs A and B. When tied to GND (default), the muxes operate normally. This allows system-level power gating or fault-safe shutdown without altering address logic.
Can MAX4692ETE+ be used with a +3V supply and 1.8V logic levels?
Yes, MAX4692ETE+ is fully compatible with +3V single supply and 1.8V logic inputs. At V+ = +3V, VIH is guaranteed ≥1.4V and VIL ≤0.4V, accommodating standard 1.8V CMOS logic. This eliminates level shifters in battery-powered systems using modern low-voltage MCUs, while maintaining ≤70Ω max RON and rail-to-rail analog performance.
Is the exposed pad (EP) on MAX4692ETE+ electrically connected?
Yes, the exposed pad (EP) on MAX4692ETE+ is internally connected to V+ and must be soldered to a V+ copper pour on the PCB. This connection improves thermal dissipation and reduces package inductance, directly supporting the device's 1349mW continuous power dissipation rating at +70°C and enhancing stability in high-frequency analog paths.
