Product details
Overview
The MAX4692EGE-T from Maxim Integrated is a dual 4-channel analog multiplexer 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 matching, rail-to-rail signal handling, and guaranteed break-before-make switching. It is used in audio/video routing and battery-powered communications circuits where low leakage (±20nA max) and fast transition (<90ns) are critical.
For engineers reviewing the MAX4692EGE-T datasheet, MAX4692EGE-T pinout, MAX4692EGE-T application, or MAX4692EGE-T equivalent, this page provides verified electrical specifications, UCSP/QFN package mapping, functional truth table alignment, supply voltage compatibility (±5V / +5V), and real-world design implications for signal integrity and power sequencing.
Technical Context
The MAX4692EGE-T implements two independent 4:1 analog multiplexers sharing address inputs A and B, with separate common outputs X and Y. Each mux supports bidirectional rail-to-rail signal transfer across its full analog range (0V to V+ or V− to V+ under dual supply).
It uses CMOS transmission-gate architecture with integrated logic-level translators enabling 1.8V-compatible digital control at +3V supply and TTL compatibility at +5V. Internal ESD diodes clamp analog pins to V+ and V−, requiring strict adherence to supply sequencing-V+ first, then V−, then logic and analog signals-to prevent latch-up or overstress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | Dual independent 4:1 analog multiplexer (X and Y sections) |
| Supply Range | +2V to +11V single supply; ±2V to ±5.5V dual supply (MAX4692 supports both) |
| Max RON | 35Ω at +5V supply - ensures minimal signal attenuation in precision analog paths |
| RON Matching | 3Ω max between channels - preserves gain/phase balance in differential or parallel signal paths |
| Leakage Current | ±20nA max at +85°C - maintains DC accuracy in high-impedance sensor or bias networks |
| Transition Time | 90ns max tTRANS at +5V - supports audio-band and low-MHz data switching without distortion |
| Off-Isolation | −80dB at 100kHz - prevents crosstalk between inactive channels in multi-source systems |
Pinout & Package
The MAX4692EGE-T is packaged in a 16-pin QFN-EP (4mm × 4mm) with exposed pad. Pin functions are validated per Maxim's official datasheet Rev 6 (1/2012), Figure 10 (MAX4692 pin configuration).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| X0–X3 | Analog Inputs (X-mux) | Four selectable input sources for X-output path; bidirectional, rail-to-rail capable |
| Y0–Y3 | Analog Inputs (Y-mux) | Four selectable input sources for Y-output path; electrically isolated from X section |
| X | X-mux Common Output | Single-ended output node for X-section; connects to selected X0–X3 when enabled |
| Y | Y-mux Common Output | Single-ended output node for Y-section; connects to selected Y0–Y3 when enabled |
| A, B | Digital Address Inputs | Shared 2-bit binary select for both muxes; A = LSB, B = MSB |
| EN | Digital Enable Input | Active-low; drives all switches open when high - enables system-level power gating |
| V+ | Positive Supply | Powers analog switches and internal logic; must be bypassed with 0.1µF capacitor |
| V− | Negative Supply | Required for dual-supply operation; connect to GND for single-supply mode |
| GND | Digital Ground Reference | Logic reference only; analog signals float between V+ and V− with no ground dependency |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ - eliminates level-shifting in bipolar or wide-dynamic-range systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4692ETE+T | Same functionality and specs; packaged in 16-pin TQFN-EP (4mm × 4mm) instead of QFN-EP | Identical electrical behavior; differs only in thermal pad geometry and moisture sensitivity rating | Select for designs requiring tighter thermal resistance or JEDEC-standard TQFN footprint |
| ADG732BRUZ | 32-channel, single-supply-only (1.8V–5.5V); 4.5Ω RON at 3V but no dual-supply support or break-before-make guarantee | Higher channel count but lacks bipolar operation and guaranteed switching sequence | Choose only for low-voltage, high-density routing where ±5V rails and fault-safe switching are unnecessary |
Compared with MAX4692ETE+T, the MAX4692EGE-T offers identical analog performance with marginally better thermal dissipation in QFN-EP; versus ADG732BRUZ, it trades channel count for robust dual-supply operation, guaranteed break-before-make, and superior off-isolation-making it preferable for industrial and telecom signal routing where supply flexibility and reliability are mandatory.

FAQ
What supply configurations does the MAX4692EGE-T support?
The MAX4692EGE-T operates from either a single +2V to +11V supply (with V− tied to GND) or dual ±2V to ±5.5V supplies. It is fully specified across both modes, with on-resistance degrading predictably below +2.7V. The device requires proper sequencing: V+ first, then V− (if used), then logic and analog signals - failure to follow this risks ESD diode conduction and latch-up.
How are the two 4:1 multiplexers controlled in the MAX4692EGE-T?
The MAX4692EGE-T uses shared digital address inputs A and B to control both the X-mux (X0–X3 → X) and Y-mux (Y0–Y3 → Y) simultaneously. A 2-bit binary code selects one input per section: e.g., A=0/B=0 selects X0 and Y0. The EN pin disables both muxes when driven high. No separate C input is present - unlike the MAX4691, which uses A/B/C for 8:1 selection.
Does the MAX4692EGE-T provide guaranteed break-before-make switching?
Yes, the MAX4692EGE-T guarantees break-before-make operation with a minimum 2ns dead time between channel transitions, confirmed in the datasheet's Electrical Characteristics table under "Break-Before-Make" (tBBM) for all supply conditions. This prevents momentary shorts during address changes - essential for protecting downstream amplifiers or avoiding signal corruption in fault-critical paths.
What is the maximum leakage current specification for the MAX4692EGE-T at elevated temperature?
The MAX4692EGE-T specifies ±20nA maximum off-leakage current (IX(OFF), IY(OFF)) over the full operating temperature range of −40°C to +85°C, per the Electrical Characteristics tables for +5V supply. At +25°C, typical leakage is ±2nA. This low leakage ensures minimal DC error in high-impedance sensor interfaces and precision reference routing.
Can the MAX4692EGE-T be used with 1.8V logic-level control signals?
Yes - when operated from a +3V supply, the MAX4692EGE-T accepts 1.8V logic-compatible inputs (VIH = +1.4V min, VIL = +0.4V max). This allows direct interfacing with 1.8V microcontrollers or FPGAs without level shifters. At +5V supply, it meets TTL thresholds (VIH = +2.0V min, VIL = +0.8V max), ensuring compatibility across mixed-voltage digital systems.
