Product details
Overview
MAX4608CSE+T from Maxim Integrated is a dual, normally open (NO), single-pole single-throw (SPST) CMOS analog switch with 2.5Ω max on-resistance, rail-to-rail signal handling (±15V dual or +12V single supply), and 2.5nA max off-leakage at +85°C. It operates across -40°C to +85°C and is used in automated test equipment for low-distortion signal routing where mechanical relay replacement is required.
For engineers reviewing the MAX4608CSE+T datasheet, MAX4608CSE+T pinout, MAX4608CSE+T application, or MAX4608CSE+T equivalent, key selection criteria include guaranteed RON match (≤0.5Ω), flat on-resistance over signal range, TTL/CMOS-compatible logic thresholds, and SO-16 narrow package compatibility with high-density PCB layouts.
Technical Context
The MAX4608CSE+T implements dual independent SPST switches with NO configuration, each controlled by separate digital inputs (IN1, IN2) referenced to VL. Its BiCMOS process enables low charge injection (45pC) and high off-isolation (-60dB at 1MHz), critical for precision sampling and multiplexing.
It supports both single-supply (+4.5V to +36V) and dual-supply (±4.5V to ±20V) operation, with logic inputs guaranteed compatible at +12V or ±15V supplies via fixed 0.8V/2.4V thresholds - eliminating level-shifter requirements in mixed-voltage systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 2.5Ω max - ensures minimal voltage drop and signal attenuation in low-level analog paths. |
| RON Match Between Channels | 0.5Ω max - enables matched gain/attenuation in differential or dual-path signal conditioning. |
| RON Flatness | 0.5Ω max over full signal range - preserves linearity for audio, sensor, and instrumentation signals. |
| Off-Leakage Current | 2.5nA max at +85°C - prevents DC error accumulation in high-impedance sensor front-ends. |
| Turn-On/Turn-Off Time | 110ns / 150ns - supports switching rates up to ~5MHz in time-critical multiplexing applications. |
| Supply Range | +4.5V to +36V (single) or ±4.5V to ±20V (dual) - accommodates industrial, avionics, and test-equipment power architectures. |
| ESD Protection | >2kV per Method 3015.7 - enhances robustness during board handling and system integration. |
Pinout & Package
MAX4608CSE+T is housed in a 16-pin narrow SOIC (SO-16) package, RoHS-compliant and lead-free, with 1.27mm pitch and standard JEDEC MS-012AC outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6, 8, 10, 15 | No Connection (N.C.) | Not internally bonded; connect to GND for improved off-isolation and noise immunity. |
| 2, 7 | Logic Input (IN1, IN2) | TTL/CMOS-compatible control lines; active-high drives respective NO switch closed. |
| 4 | Negative Analog Supply (V−) | Analog ground reference for dual-supply operation; tie to DGND for single-supply use. |
| 5 | Ground (GND) | Digital ground return; must be low-impedance and tied to V− in single-supply configurations. |
| 9, 16 | Normally Open Terminal (NO1, NO2) | Switch output node; connects to COM when corresponding IN is high. |
| 11, 14 | Common Terminal (COM1, COM2) | Analog signal path input; carries rail-to-rail signals up to ±15V or +12V. |
| 12 | Logic Supply (VL) | Independent 2.7V–5.5V logic interface supply; decouples logic threshold from analog rails. |
| 13 | Positive Analog Supply (V+) | Main analog rail; supports up to +36V or +20V in dual mode; defines upper signal limit. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports input signals from V− to V+, enabling direct interfacing with op-amps, ADCs, and DACs without level shifting. |
| Guaranteed RON flatness ≤0.5Ω | Maintains consistent channel gain across full analog range - essential for audio fidelity and measurement accuracy. |
| Low charge injection (45pC) | Minimizes voltage glitch on sampled-hold nodes, reducing settling time and improving ADC effective resolution. |
| TTL/CMOS-compatible logic inputs | Eliminates need for external level translators when driving from microcontrollers or FPGAs operating at +3.3V or +5V. |
| 2.5nA max off-leakage at +85°C | Preserves signal integrity in high-impedance sensor interfaces (e.g., pH electrodes, piezoelectric transducers). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1419BRUZ | Higher RON (3.8Ω typ), wider supply (±15V only), no VL pin - logic tied to V+. | Requires level-shifting for 3.3V controllers; less suitable for mixed-voltage systems. | Preferred when ultra-low charge injection (20pC) outweighs RON and logic flexibility trade-offs. |
| TS5A23157DCUR | Lower voltage rating (+5.5V max), smaller 8-pin VSSOP package, higher RON (0.9Ω typ at 3.3V). | Limited to low-voltage consumer/portable gear; not rated for industrial or avionics signal ranges. | Select for cost-sensitive, space-constrained designs where ±15V operation and wide temp range are unnecessary. |
Compared with ADG1419BRUZ and TS5A23157DCUR, MAX4608CSE+T uniquely combines rail-to-rail ±15V capability, independent VL logic supply, and guaranteed RON matching - making it optimal for industrial ATE and high-fidelity signal routing where supply flexibility and channel consistency are critical.

FAQ
What is the maximum analog signal voltage range supported by MAX4608CSE+T?
MAX4608CSE+T supports rail-to-rail analog signals from V− to V+. In dual-supply mode (±15V), this is ±15V; in single-supply mode (+12V), it is 0V to +12V. Absolute maximum ratings allow V+ up to +36V and V− down to -44V relative to GND, but operational signal range remains bounded by the applied supply rails. The device maintains 2.5Ω max RON across this full range.
Does MAX4608CSE+T require external level shifters when driven by a 3.3V microcontroller?
No. MAX4608CSE+T features TTL/CMOS-compatible logic inputs with guaranteed thresholds of +0.8V (low) and +2.4V (high), fully compatible with 3.3V logic outputs. Its VL pin accepts 2.7V–5.5V, allowing direct connection to a 3.3V supply - eliminating external level shifters while maintaining noise margin and reliable switching.
How does the VL pin function in MAX4608CSE+T, and can it be tied to V+?
The VL pin sets the logic threshold reference independently of analog supplies. It must be connected to a stable 2.7V–5.5V source - typically +3.3V or +5V - and should not be tied to V+, which may exceed 5.5V and damage the logic interface. Separating VL from V+ enables robust operation in mixed-supply systems and prevents logic malfunction during analog rail transients.
What is the thermal performance of MAX4608CSE+T in its SO-16 package at +85°C ambient?
In the narrow SO-16 package, MAX4608CSE+T has a thermal resistance θJA of approximately 115°C/W. At +85°C ambient and 100mA per channel (worst-case power dissipation ~250mW), junction temperature remains within safe limits (<125°C). Derating begins above +70°C at 8.70mW/°C, supporting continuous operation across its full -40°C to +85°C industrial temperature range.
Can MAX4608CSE+T be used in high-frequency RF signal paths above 10MHz?
MAX4608CSE+T is not characterized for RF operation above 5MHz. While its on-response extends beyond 100MHz with proper layout, off-isolation degrades rapidly above 30MHz due to capacitive coupling. For frequencies >5MHz, Maxim recommends the MAX440/MAX441/MAX442 series, which are fully specified up to 160MHz. MAX4608CSE+T is best suited for audio, DC–1MHz instrumentation, and multiplexing applications.
