Product details
Overview
The MAX4691EGE+T from Maxim Integrated is an 8-channel analog multiplexer IC configured as a single-pole, 8-throw (SP8T) switch with rail-to-rail signal handling, 25Ω max on-resistance at ±4.5V dual supplies, guaranteed break-before-make timing (2ns), and 1.8V logic compatibility at +3V operation. It serves in precision signal routing for portable audio interfaces and battery-powered instrumentation.
For engineers reviewing the MAX4691EGE+T datasheet, MAX4691EGE+T pinout, MAX4691EGE+T application, or MAX4691EGE+T equivalent, this page delivers verified electrical specs, UCSP/QFN package mapping, channel-matching performance data, and real-world audio/video routing use cases - all confirmed against Maxim's official 19-1945 Rev 6 datasheet.
Technical Context
The MAX4691EGE+T implements a CMOS transmission-gate architecture with independent V+ and V− supply rails, enabling true bipolar analog signal switching from −4.5V to +4.5V. Its address decoding uses three digital inputs (A/B/C) to select one of eight bidirectional analog paths between common X and inputs X0–X7.
Internal logic-level translators convert 1.8V/3.3V/5V-compatible digital inputs into full-rail gate drive signals, decoupling logic and analog domains. The device guarantees break-before-make operation (2ns min) and exhibits ≤3.5Ω RON flatness over its full analog range, critical for low-distortion audio path selection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | Rail-to-rail: 0V to V+ (single-supply) or V− to V+ (dual-supply); supports ±4.5V operation without clipping. |
| On-Resistance (RON) | 25Ω max at ±4.5V; ensures minimal voltage drop and gain error in precision sensor or audio signal chains. |
| RON Matching | 3Ω max between channels at ±4.5V; enables accurate multi-channel calibration and matched filter banks. |
| Break-Before-Make Time | 2ns minimum; prevents momentary short-circuiting during channel switching in sensitive analog systems. |
| Leakage Current | ±20nA max at +85°C; preserves DC accuracy in high-impedance sensor front-ends and battery-monitoring circuits. |
| Switching Speed | tON = 50ns typ, tOFF = 90ns typ at ±5V; supports fast multiplexing in data acquisition and real-time control loops. |
| Logic Compatibility | 1.8V input threshold at +3V supply; allows direct interface with ultra-low-power microcontrollers and FPGAs. |
Pinout & Package
The MAX4691EGE+T is supplied in a 16-pin QFN-EP (4mm × 4mm) package with exposed pad. Pin numbering follows standard QFN layout (pin 1 at top-left corner, counterclockwise).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| X | Analog Common Output | Single bidirectional output node shared across all 8 channels; connects to ADC input or amplifier stage. |
| X0–X7 | Analog Inputs 0–7 | Bidirectional analog signal terminals; each routed to X only when selected by A/B/C address bits. |
| A, B, C | Digital Address Inputs | 3-bit binary code selects active channel (e.g., A=0,B=0,C=0 → X0; A=1,B=1,C=1 → X7). |
| EN | Enable Input | Active-low enable: EN = GND enables switching; EN = V+ disables all channels (high-Z state). |
| V+ | Positive Supply | Supplies analog switches and internal logic; must be bypassed with 0.1µF capacitor near pin. |
| V− | Negative Supply | Required for dual-supply operation; connect to GND for single-supply mode (+2V to +11V). |
| GND | Digital Ground Reference | Reference for EN and address inputs; separate from analog signal ground (no analog ground reference). |
| EP | Exposed Pad | Thermal and electrical connection to V+; must be soldered to PCB copper pour for thermal dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports full-swing signals from V− to V+, eliminating level-shifting circuitry in ±5V systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4691EBE+T | Same functionality and specs, but in 2mm × 2mm 16-bump UCSP package instead of QFN. | Preferred for ultra-compact PCBs where space is constrained; requires specialized assembly process for UCSP reliability. | Select MAX4691EBE+T only if board area is critical and UCSP assembly capability is validated. |
| ADG708BRUZ | 8-channel CMOS mux with 4.5Ω RON at +5V, but no dual-supply support and higher 25nA leakage at +85°C. | Suitable for single-supply +3V/+5V systems only; lacks rail-to-rail operation below +2.7V and ±5V capability. | Choose ADG708BRUZ for cost-sensitive, single-rail designs where low RON at +5V is prioritized over wide supply range. |
Compared with MAX4691EBE+T and ADG708BRUZ, the MAX4691EGE+T uniquely balances ultra-low leakage, dual-supply flexibility, and QFN manufacturability - making it optimal for industrial portable instruments requiring both precision and production scalability.

FAQ
What supply voltages does the MAX4691EGE+T support?
The MAX4691EGE+T operates from a single +2V to +11V supply (with V− tied to GND) or dual ±2V to ±5.5V supplies. At ±4.5V, it achieves 25Ω max on-resistance and guaranteed break-before-make timing. The MAX4691EGE+T datasheet specifies absolute maximum ratings up to +12V on V+ and −0.3V to +12V on V+ to V− differential, ensuring robustness in varied power environments.
Does the MAX4691EGE+T require external level-shifting for 1.8V logic inputs?
No, the MAX4691EGE+T features native 1.8V logic compatibility when operated from a +3V supply - VIH is guaranteed at +1.4V min and VIL at +0.4V max. This eliminates external level shifters when interfacing with low-voltage microcontrollers. The MAX4691EGE+T maintains TTL compatibility at +5V supply (VIH = +2V min), supporting mixed-voltage system integration without additional components.
How is channel selection implemented on the MAX4691EGE+T?
Channel selection on the MAX4691EGE+T is controlled by three digital address inputs (A, B, C) that decode a 3-bit binary value to activate one of eight analog paths (X0–X7) to the common output X. For example, A=0/B=0/C=0 selects X0, while A=1/B=1/C=1 selects X7. The enable input (EN) must be low to activate switching; pulling EN high places all switches in high-impedance off-state. This logic is fully detailed in Table 1 of the MAX4691EGE+T datasheet.
What is the thermal performance of the MAX4691EGE+T in its QFN-EP package?
The MAX4691EGE+T in the 16-pin QFN-EP package has a continuous power dissipation rating of 1481mW at TA = +70°C, with thermal derating of 18.5mW/°C above that temperature. Its exposed pad (EP) must be soldered to a V+-connected PCB copper pour to achieve this rating. Thermal resistance θJA is optimized for surface-mount layouts, enabling reliable operation in compact enclosures without forced airflow - a key advantage over SOIC packages for portable MAX4691EGE+T implementations.
Can the MAX4691EGE+T be used in bipolar signal paths without external clamping diodes?
Yes - the MAX4691EGE+T integrates reverse ESD-protection diodes between each analog pin and both V+ and V−, enabling safe bipolar signal handling from V− to V+ without external clamping. However, analog signals must remain within (V− − 0.3V) to (V+ + 0.3V) to avoid forward-biasing these diodes. For overvoltage protection beyond absolute maximum ratings, external series diodes (as shown in Figure 1 of the MAX4691EGE+T datasheet) are recommended - but not required for normal ±4.5V operation.
