Product details
Overview
The MAX4599EXT-G103 from Maxim Integrated is a low-voltage, single-supply SPDT analog switch designed for bidirectional signal routing in space-constrained systems. It delivers 60Ω max on-resistance at +5V, 30ns max turn-on time, 5pC max charge injection, and operates from +2.0V to +5.5V - enabling use in battery-powered audio routing and low-voltage data-acquisition circuits.
For engineers reviewing the MAX4599EXT-G103 datasheet, MAX4599EXT-G103 pinout, MAX4599EXT-G103 application, or MAX4599EXT-G103 equivalent, key selection criteria include on-resistance flatness (4Ω max), break-before-make timing (10ns typ), -76dB off-isolation at 1MHz, and SC70-6 package compatibility with high-density PCB layouts.
Technical Context
The MAX4599EXT-G103 implements a CMOS-based transmission-gate architecture optimized for low-voltage operation, supporting rail-to-rail analog signal switching (GND to V+) without degradation in RON flatness. Its digital control interface accepts TTL/CMOS logic levels across the full supply range (+2.0V to +5.5V), eliminating level-shifting requirements.
It features guaranteed break-before-make timing (10ns typ) to prevent signal shorting during state transitions, and integrates internal ESD protection diodes rated to ±2kV HBM. The device maintains 200MHz -3dB bandwidth and 0.12% THD in audio-frequency paths, validated under +25°C and full -40°C to +85°C operating conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.0V to +5.5V single supply - enables direct integration with Li-ion, 3.3V, and 5V logic domains without external regulators. |
| On-Resistance (RON) | 60Ω max at +5V - ensures minimal signal attenuation and voltage drop in precision sensor or audio signal paths. |
| RON Flatness | 4Ω max over full signal range - preserves linearity and gain accuracy in sample-and-hold and instrumentation amplifier interfaces. |
| Charge Injection | 5pC max - reduces settling error and pedestal distortion in switched-capacitor and ADC front-end applications. |
| Off-Isolation | -76dB at 1MHz - suppresses crosstalk between active and inactive channels in multi-source video/audio routing. |
| Bandwidth (-3dB) | 200MHz - supports high-fidelity analog signal switching up to UHF frequencies, including IF stages in RF receivers. |
| Leakage Current | ±0.5nA max at +25°C - minimizes DC error accumulation in high-impedance sensor nodes and battery-monitoring circuits. |
Pinout & Package
The MAX4599EXT-G103 is housed in a 6-pin SC70-6 package (2.0mm × 1.25mm, 0.5mm pitch), optimized for ultra-compact portable designs. Pin 1 is marked with a dot; the package is RoHS-compliant and moisture-sensitive level 1 (MSL1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Digital Control Input | Active-high TTL/CMOS-compatible logic input controlling switch state; drives internal transmission gate driver. |
| 2 V+ | Positive Supply Rail | Single power supply input; must be applied before analog signals to avoid latch-up or ESD stress on internal protection diodes. |
| 3 GND | Ground Reference | Analog and digital ground reference; requires low-impedance connection to minimize noise coupling into sensitive analog paths. |
| 4 NC | Normally Closed Terminal | Analog path connected to COM when IN = low; electrically isolated from all other pins when open (no internal tie). |
| 5 COM | Common Analog Terminal | Bidirectional signal port - serves as input or output depending on system topology; supports rail-to-rail voltage swing (GND to V+). |
| 6 NO | Normally Open Terminal | Analog path connected to COM when IN = high; exhibits identical RON, leakage, and capacitance specs as NC terminal. |
Key Features
| Feature | Design Value |
|---|---|
| Break-Before-Make Switching | Guaranteed 10ns minimum dead time prevents momentary shorting between NO and NC paths during transition - critical for protecting downstream amplifiers and ADC inputs. |
| RON Matching Between Channels | 1Ω max mismatch ensures matched gain/attenuation in differential or dual-path signal routing (e.g., stereo audio channel switching). |
| Low Charge Injection (5pC max) | Minimizes voltage glitch on sampled capacitors - enables accurate DC-coupled sampling in precision data acquisition without recalibration overhead. |
| 200MHz On-Channel Bandwidth | Preserves signal integrity for composite video, USB 1.1 analog signaling, and intermediate-frequency (IF) switching in SDR front-ends. |
| TTL/CMOS Logic Compatibility | Accepts standard logic thresholds across entire supply range - eliminates need for external level shifters when interfacing with mixed-voltage microcontrollers. |
Applications
| Portable Audio Routing | Low-Voltage Data Acquisition |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4699EXT-T | Same SC70-6 package, but 100Ω max RON at +5V and 100MHz bandwidth - higher on-resistance and lower bandwidth than MAX4599EXT-G103. | Less suitable for high-fidelity audio or wideband RF routing; better suited for cost-sensitive industrial I/O where bandwidth < 100MHz is acceptable. | Select MAX4699EXT-T only if RON tolerance > 100Ω and bandwidth < 100MHz meet system requirements - not a drop-in replacement. |
| TMUX1574DSGR | TI part in 6-pin WSON (2.0mm × 2.0mm); 4.5Ω typical RON at +3.3V but requires dual supply (±2.5V) or level-shifted control for single-supply systems. | Superior RON and flatness, but incompatible pinout and control interface - demands PCB redesign and logic-level adaptation. | Choose TMUX1574DSGR only when ultra-low RON and thermal drift performance outweigh layout rework costs and supply complexity. |
Compared with MAX4599EXT-G103, MAX4699EXT-T trades bandwidth and on-resistance for cost reduction, while TMUX1574DSGR offers superior analog specs at the expense of single-supply simplicity and pin compatibility - making MAX4599EXT-G103 optimal for compact, battery-powered designs requiring balanced speed, linearity, and ease of integration.

FAQ
What is the maximum supply voltage rating for the MAX4599EXT-G103?
The MAX4599EXT-G103 has an absolute maximum supply voltage (V+) of +6V, but its recommended operating range is +2.0V to +5.5V. Exceeding +6V risks permanent damage per Absolute Maximum Ratings. Operation at +5.5V ensures full specification compliance for RON, switching speed, and leakage - the MAX4599EXT-G103 is not rated for 6V continuous operation despite the 6V absolute limit.
Does the MAX4599EXT-G103 support rail-to-rail analog signal switching?
Yes, the MAX4599EXT-G103 supports rail-to-rail analog signal switching from GND to V+, verified across its full operating temperature range (-40°C to +85°C). Its transmission-gate design maintains low and flat on-resistance (4Ω max flatness) over this range, enabling accurate DC-coupled signal routing without clipping or gain nonlinearity - a core capability confirmed in the MAX4599EXT-G103 Typical Operating Characteristics graphs.
What is the guaranteed break-before-make interval for the MAX4599EXT-G103?
The MAX4599EXT-G103 guarantees a minimum break-before-make (BBM) interval of 10ns, measured under standard test conditions (V+ = +5.5V, VCOM = 1V/4.5V). This timing prevents simultaneous conduction between NO and NC paths, protecting downstream circuitry from short-circuit transients - a requirement explicitly specified in the MAX4599EXT-G103 Electrical Characteristics table under "tBBM".
Can the MAX4599EXT-G103 be used with a +3.3V supply while maintaining full performance?
Yes, the MAX4599EXT-G103 is fully characterized and specified at +3.3V (within its +2.7V to +3.6V single-supply range). At +3.3V, it delivers 95Ω max RON, 45ns max tON, and retains all key specs including 5pC max charge injection and -76dB off-isolation - confirming robust operation in standard 3.3V embedded systems without derating or performance loss.
Is the SC70-6 package of the MAX4599EXT-G103 compatible with standard reflow profiles?
Yes, the MAX4599EXT-G103 in SC70-6 package complies with IPC/JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) and supports standard Pb-free reflow profiles (peak temperature ≤ 260°C). Its 0.5mm pitch and 2.0mm × 1.25mm footprint are compatible with automated placement and reflow soldering processes used in high-volume manufacturing - no special handling or baking required prior to assembly.
