Product details
Overview
The MAX4599EXT+T from Maxim Integrated is a low-voltage, single-supply SPDT analog switch in SC70-6 package, featuring 60Ω max on-resistance at +5V, 30ns max turn-on time, 5pC max charge injection, and break-before-make switching-designed for precision audio routing in battery-powered portable devices.
For engineers reviewing the MAX4599EXT+T datasheet, MAX4599EXT+T pinout, MAX4599EXT+T application, or MAX4599EXT+T equivalent, key selection criteria include on-resistance flatness (4Ω max), channel matching (1Ω max), -76dB off-isolation at 1MHz, 200MHz -3dB bandwidth, and guaranteed operation from +2.0V to +5.5V supply.
Technical Context
The MAX4599EXT+T implements a CMOS-based SPDT switch architecture with TTL/CMOS-compatible digital control (VIH = 2.4V min, VIL = 0.8V max at +5V supply) and bidirectional analog signal handling across the full 0V to V+ range. Its internal structure ensures break-before-make timing (10ns typ at +25°C) to prevent signal shorting during state transitions.
It delivers low distortion (0.12% THD) and minimal capacitive loading (8pF off-capacitance per NO/NC, 20pF on-capacitance), enabling high-fidelity signal routing in audio paths and low-noise data-acquisition front-ends without requiring external buffering or level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.0V to +5.5V single supply - enables direct integration into 3.3V and 5V systems without level shifters. |
| On-Resistance (RON) | 60Ω max at +5V - ensures minimal voltage drop and signal attenuation in low-current analog paths. |
| RON Matching | 1Ω max between channels - critical for matched gain/attenuation in differential or dual-path signal routing. |
| Charge Injection | 5pC max - limits voltage glitch on sampled nodes in sample-and-hold or multiplexed ADC applications. |
| -3dB Bandwidth | 200MHz - supports high-speed video, RF IF routing, and wideband communications signals. |
| Off-Isolation | -76dB at 1MHz - suppresses crosstalk between inactive channels in multi-source audio/video systems. |
| Leakage Current | ±0.5nA max at +25°C - preserves accuracy in high-impedance sensor interfaces and battery-monitoring circuits. |
Pinout & Package
MAX4599EXT+T is housed in a RoHS-compliant 6-pin SC70-6 package (outline X6SN-1, land pattern 90-0189), measuring 2.0mm × 1.25mm × 0.95mm, optimized for space-constrained portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Digital control input | TTL/CMOS-compatible logic signal that selects NO or NC path; active-high with VIH ≥ 2.4V at V+ = 5V. |
| 2 - V+ | Positive supply rail | Single power connection supporting 2.0V–5.5V; must be applied before analog/logic signals to avoid latch-up. |
| 3 - GND | Ground reference | Analog and digital common return; requires low-impedance connection to minimize noise coupling. |
| 4 - N.C. | Normally closed analog terminal | Connected to COM when IN = low; open-circuit when IN = high - used for default signal path selection. |
| 5 - COM | Common analog I/O node | Bidirectional port handling source or load; supports full 0V to V+ signal swing with <4Ω RON flatness. |
| 6 - NO | Normally open analog terminal | Connected to COM when IN = high; open-circuit when IN = low - enables active signal routing control. |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed 10ns minimum interval prevents momentary shorting between NO and NC paths during transition. |
| Low charge injection (5pC max) | Minimizes voltage transients on high-impedance nodes, preserving integrity in sample-and-hold and multiplexed ADC inputs. |
| 200MHz -3dB bandwidth | Enables transparent routing of composite video, USB 1.1, and baseband RF signals without amplitude roll-off. |
| RON flatness (4Ω max) | Ensures consistent gain/attenuation across full analog signal range (0V to V+), critical for line-level audio fidelity. |
| ±0.5nA leakage (25°C) | Reduces error in microamp-level sensor interfaces and battery voltage monitoring circuits over temperature. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS5A23157DCUR | Lower RON (0.9Ω typ at 3.3V) but higher charge injection (12pC typ); 5V absolute max supply. | Better for low-RON power-switching; less suitable for precision sampling due to higher charge injection. | Select TS5A23157DCUR only if RON <1Ω is mandatory and charge injection tolerance >10pC exists. |
| ADG821BRMZ | Higher supply range (up to 5.5V), but slower switching (tON/tOFF = 15ns typ), and no guaranteed break-before-make. | Preferred for general-purpose routing where timing margin allows; not recommended for glitch-sensitive sampling. | Choose ADG821BRMZ when layout space permits larger MSOP-8 package and break-before-make is noncritical. |
Compared with TS5A23157DCUR and ADG821BRMZ, the MAX4599EXT+T uniquely balances low charge injection (5pC), guaranteed break-before-make, and SC70-6 footprint - making it optimal for space-constrained, high-fidelity portable audio and precision sampling applications.

FAQ
What is the maximum supply voltage rating for the MAX4599EXT+T?
The MAX4599EXT+T has an absolute maximum supply voltage (V+) of +6V, but its specified operational range is +2.0V to +5.5V. Operating beyond +5.5V voids parametric guarantees and risks permanent damage. The device is rated for continuous operation at +5.5V with full performance compliance, including 60Ω max RON and 30ns max tON.
Does the MAX4599EXT+T support bidirectional analog signal flow?
Yes, the MAX4599EXT+T supports fully bidirectional analog signal routing between COM, NO, and N.C. terminals. Its CMOS switch architecture imposes no directionality constraint - any pin can serve as input or output, provided signals remain within the 0V to V+ range. This enables flexible use in both source-selection and load-switching configurations without redesign.
What is the guaranteed break-before-make interval for the MAX4599EXT+T?
The MAX4599EXT+T guarantees a minimum break-before-make (BBM) interval of 10ns at +25°C, with typical values of 13ns at +85°C and 10ns at -40°C. This BBM timing is ensured across the full -40°C to +85°C operating range and prevents momentary shorting between NO and N.C. paths during logic transitions - essential for avoiding signal corruption in audio and data paths.
Can the MAX4599EXT+T operate reliably from a +2.5V supply?
Yes, the MAX4599EXT+T is fully specified and tested for operation from +2.5V. At this supply, typical on-resistance rises to 110Ω (max 120Ω), tON/tOFF increase to 45ns/35ns (max), and VIH drops to 2.0V. All core functions - including break-before-make, charge injection (≤5pC), and analog signal range (0V to +2.5V) - remain guaranteed, making it suitable for ultra-low-power wearable systems.
What package type does the MAX4599EXT+T use, and is it RoHS compliant?
The MAX4599EXT+T uses the 6-pin SC70-6 package (outline X6SN-1), measuring 2.0mm × 1.25mm × 0.95mm. It carries the "+T" suffix indicating tape-and-reel packaging and RoHS compliance per Maxim's standard marking convention ("+" denotes RoHS). The top mark "AAF" confirms this specific variant and matches the ordering information table in the official datasheet.
