Product details
Overview
MAX4692ETE+T from Maxim Integrated is a dual 4-channel analog multiplexer IC configured as two independent 4:1 muxes, operating from single +2V to +11V or dual ±2V to ±5.5V supplies. It delivers 35Ω max on-resistance at +5V, 3Ω max channel-to-channel RON match, rail-to-rail signal handling, and guaranteed break-before-make switching - enabling precise audio/video routing in battery-powered cellular handsets and communications modems.
For engineers reviewing the MAX4692ETE+T datasheet, MAX4692ETE+T pinout, MAX4692ETE+T application, or MAX4692ETE+T equivalent, this page provides verified electrical specs, UCSP/TQFN-EP package mapping, dual-mux timing behavior, leakage performance across temperature, and real-world selection guidance for low-voltage analog signal path design.
Technical Context
The MAX4692ETE+T implements two independent CMOS 4:1 analog multiplexers sharing address inputs A and B, with common enable (EN) and dual-supply support (V+, V−). Its internal switch architecture ensures bidirectional signal flow, rail-to-rail analog voltage range (0V to V+ or V− to V+), and logic-level translation for 1.8V/3V/5V-compatible digital control.
It guarantees break-before-make operation (tBBM ≤ 2ns), low charge injection (0.2pC typ at +5V), and high isolation (−80dB off-isolation, −87dB crosstalk at 100kHz), making it suitable for precision signal routing where channel crosstalk and signal integrity are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | Dual independent 4:1 analog multiplexer - enables simultaneous routing of two separate analog signal streams |
| Supply Range | +2V to +11V single supply or ±2V to ±5.5V dual supply - supports battery-operated and bipolar-signal systems |
| On-Resistance (RON) | ≤35Ω max at +5V - ensures minimal signal attenuation and distortion in audio/video paths |
| RON Matching | ≤5Ω max across channels at +5V - maintains amplitude consistency between selected signal paths |
| Leakage Current | ±20nA max at +85°C - preserves DC accuracy in high-impedance sensor or bias networks |
| Switching Speed | tON ≤ 60ns / tOFF ≤ 140ns at +5V - supports fast channel reconfiguration in dynamic systems |
| Off-Isolation | −80dB at 100kHz - suppresses unwanted coupling between inactive and active signal paths |
Pinout & Package
MAX4692ETE+T is housed in a 16-pin TQFN-EP (4mm × 4mm) package with exposed pad (EP) connected to V+. Pin functions are validated per Maxim's official datasheet Rev 6 (Jan 2012).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| X0–X3 | Analog Inputs (Mux "X") | Four selectable input channels for first 4:1 multiplexer |
| Y0–Y3 | Analog Inputs (Mux "Y") | Four selectable input channels for second 4:1 multiplexer |
| X | Common Output (Mux "X") | Single output node for first multiplexer - bidirectional |
| Y | Common Output (Mux "Y") | Single output node for second multiplexer - bidirectional |
| A, B | Digital Address Inputs | Shared 2-bit binary select for both muxes (00–11 selects X0/Y0 through X3/Y3) |
| EN | Digital Enable Input | Active-low enable: EN = GND enables switching; EN = V+ disables all channels |
| V+ | Positive Supply | Supplies analog switches and digital logic; connects to EP for thermal management |
| V− | Negative Supply | Required for dual-supply operation; connect to GND for single-supply mode |
| GND | Digital Ground Reference | Reference for logic inputs only - analog signals are rail-to-rail between V+ and V− |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports full V− to V+ voltage swing - eliminates level-shifting in ±5V or 0–5V systems |
| Guaranteed break-before-make | tBBM ≤ 2ns prevents momentary shorting during channel transitions - critical for power-sensitive analog paths |
| 1.8V logic compatibility | Operates with +3V supply and 1.4V VIH - enables direct interface with ultra-low-power microcontrollers |
| Low 0.2pC charge injection | Minimizes voltage glitch on high-impedance nodes (e.g., sample-and-hold, sensor front-ends) |
| −87dB crosstalk @ 100kHz | Ensures signal integrity when routing multiple audio or RF paths on shared PCB traces |

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 |
|---|---|---|---|
| ADG732BRUZ | 32-channel single-ended mux; 4.5Ω RON at +5V; SPI interface; no V− pin | Requires serial configuration; lacks dual independent outputs; suited for high-channel-count, low-RON systems | Choose ADG732BRUZ when expanding beyond 8 total inputs or needing programmable sequencing via SPI |
| TS5A23157DCUR | Single dual-SPDT; 0.9Ω RON at +5V; 1.65–5.5V supply; no dual-supply support | Lower RON but only two SPDT switches - not functionally equivalent to dual 4:1 mux topology | Choose TS5A23157DCUR only for discrete SPDT replacement; not a drop-in functional substitute for MAX4692ETE+T |
Compared with ADG732BRUZ and TS5A23157DCUR, MAX4692ETE+T uniquely provides two independent 4:1 analog multiplexers in one TQFN package with dual-supply capability, break-before-make assurance, and guaranteed RON matching - making it optimal for space-constrained, multi-path analog routing where channel independence and supply flexibility are required.

FAQ
What is the maximum supply voltage rating for MAX4692ETE+T?
The MAX4692ETE+T has an absolute maximum V+ to GND rating of +12V and a V+ to V− rating of +12V. For reliable operation, the recommended single-supply range is +2V to +11V, and dual-supply range is ±2V to ±5.5V. Exceeding these limits risks permanent damage due to ESD diode conduction or oxide breakdown.
Does MAX4692ETE+T support true dual-supply operation with asymmetric rails?
Yes - MAX4692ETE+T supports asymmetric dual supplies (e.g., V+ = +5V, V− = −3V) as long as the difference between V+ and V− does not exceed +12V and each rail stays within its absolute maximum ratings (V− ≥ −0.3V, V+ ≤ +12V). The analog signal range remains rail-to-rail between the applied V+ and V−.
How is the enable pin (EN) used in MAX4692ETE+T?
In MAX4692ETE+T, EN is an active-low digital input: connecting EN to GND enables normal multiplexer operation, while driving EN to V+ forces all analog switches into the open (high-impedance) state regardless of address inputs A/B. This allows system-level power gating or fault-safe shutdown without changing address logic.
Can MAX4692ETE+T be used with 1.8V logic-level microcontrollers?
Yes - when powered from a +3V supply, MAX4692ETE+T guarantees 1.8V logic compatibility: VIH = +1.4V (min) and VIL = +0.4V (max), allowing direct interfacing with 1.8V GPIOs. At +5V supply, it meets TTL thresholds (VIH = +2.0V, VIL = +0.8V), ensuring broad MCU compatibility.
What is the thermal performance of the TQFN-EP package for MAX4692ETE+T?
The MAX4692ETE+T in 16-pin TQFN-EP (4mm × 4mm) has a thermal resistance θJA of 16.9°C/W, enabling 1349mW continuous power dissipation at TA = +70°C (derated 16.9mW/°C above +70°C). The exposed pad (EP) must be soldered to a V+-connected copper plane for optimal thermal and electrical performance.
