Product details
Overview
MAX4608ESE from Maxim Integrated is a dual, normally open (NO), single-pole single-throw (SPST) CMOS analog switch with 2.5Ω maximum on-resistance, rail-to-rail signal handling, and operation from ±4.5V to ±20V dual supplies or +4.5V to +36V single supply. It delivers matched on-resistance (≤0.5Ω), flat on-resistance (≤0.5Ω), and low off-leakage (2.5nA max at +85°C), making it suitable for precision reed relay replacement in automated test equipment.
For engineers reviewing the MAX4608ESE datasheet, MAX4608ESE pinout, MAX4608ESE application, or MAX4608ESE equivalent, key selection considerations include guaranteed RON matching across channels, TTL/CMOS-compatible logic thresholds (+0.8V/+2.4V), ESD protection (>2kV), and -40°C to +85°C industrial temperature rating.
Technical Context
The MAX4608ESE implements two independent SPST switches with NO configuration, each controlled by separate digital inputs (IN1, IN2) referenced to VL. Its BiCMOS process enables low distortion and high linearity over full rail-to-rail analog input ranges (V− to V+), with on-resistance flatness maintained within 0.5Ω across ±10V signal swing under 10mA load.
It supports dual-supply operation with independent V+ and V− pins, plus dedicated logic supply (VL) decoupled from analog rails-enabling robust noise isolation in mixed-signal systems. Input logic thresholds are fixed at +0.8V (low) and +2.4V (high), ensuring compatibility with both TTL and CMOS drivers without level-shifting when powered from ±15V or +12V supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 2.5Ω max at TA = −40°C to +85°C, ICCOM = 10mA - ensures minimal voltage drop and power loss in signal path |
| RON Match | 0.5Ω max between channels - critical for matched gain/attenuation in differential or dual-path routing |
| RON Flatness | 0.5Ω max over ±10V signal range - preserves linearity and THD in audio and instrumentation signals |
| Off-Leakage Current | 2.5nA max at +85°C - prevents DC error accumulation in high-impedance sensor or integrator circuits |
| Supply Range | ±4.5V to ±20V dual or +4.5V to +36V single - supports wide industrial and test-equipment voltage rails |
| Logic Thresholds | +0.8V (low), +2.4V (high) - guarantees direct interface with standard TTL/CMOS outputs without external biasing |
| ESD Protection | >2kV per Method 3015.7 - enhances reliability during board handling and system integration |
Pinout & Package
MAX4608ESE is housed in a 16-pin narrow SO (Small Outline) package, RoHS-compliant, with 1.27mm pitch and JEDEC MS-012AC outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6, 8, 10, 15 | No Connection (N.C.) | Not internally connected; recommended to tie to GND for improved off-isolation and EMI suppression |
| 2, 7 | Logic Input (IN1, IN2) | Digital control inputs for respective switches; active-high logic turns NO switch ON |
| 4 | Negative Analog Supply (V−) | Analog ground reference for dual-supply operation; connect to DGND for single-supply use |
| 5 | Ground (GND) | Digital ground reference; must be tied to system digital ground plane |
| 9, 16 | Normally Open Terminal (NO1, NO2) | Switch output terminals that connect to COM only when corresponding IN is high |
| 11, 14 | Common Terminal (COM1, COM2) | Analog signal path inputs; carry rail-to-rail signals up to ±20V or +36V |
| 12 | Logic Supply (VL) | Independent logic rail (typically +5V); isolates digital switching noise from analog paths |
| 13 | Positive Analog Supply (V+) | Analog high-side rail; supports up to +36V in single-supply mode or +20V in dual-supply mode |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without clipping - essential for full-scale sensor or DAC output routing |
| Guaranteed RON match | ≤0.5Ω channel-to-channel mismatch - enables precise dual-path signal conditioning in instrumentation front-ends |
| TTL/CMOS-compatible inputs | +0.8V/+2.4V thresholds ensure interoperability with microcontrollers and FPGAs without level shifters |
| Low charge injection (45pC) | Minimizes transient glitches in sample-and-hold or multiplexed ADC applications |
| High off-isolation (−60dB @ 1MHz) | Reduces crosstalk between switched channels in multi-signal test systems |

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 temp range (−40°C to +125°C), SPI-controlled | Requires serial interface and external decode logic; not direct logic-input drop-in | Preferred when higher temperature rating and integrated fault protection are required |
| TS5A23157DCUR | Lower voltage rating (+5.5V max), smaller 8-pin VSSOP, lower RON (0.9Ω typ) | Limited to low-voltage consumer/industrial apps; incompatible with ±15V or +24V systems | Optimal for space-constrained, battery-powered designs with 3.3V/5V rails only |
Compared with ADG1419BRUZ and TS5A23157DCUR, the MAX4608ESE uniquely balances wide supply range (±20V), guaranteed RON matching (≤0.5Ω), and industrial temperature support in a simple dual-logic-input SO package-making it the preferred choice for legacy-compatible, high-voltage analog switching where deterministic timing and minimal design change are priorities.

FAQ
What is the maximum supply voltage rating for MAX4608ESE?
The MAX4608ESE supports dual supplies from ±4.5V to ±20V and single supplies from +4.5V to +36V. Absolute maximum ratings specify V+ to GND ≤ +44V and V− to GND ≥ −44V, but continuous operation beyond ±20V or +36V is not guaranteed. Exceeding these limits risks permanent damage per the Absolute Maximum Ratings table.
Does MAX4608ESE support rail-to-rail analog signal switching?
Yes, MAX4608ESE supports true rail-to-rail analog signal switching - signals at COM1/COM2 can swing from V− to V+ without clipping or distortion. This capability is confirmed in the Electrical Characteristics tables and General Description, and applies across the full −40°C to +85°C operating range.
What is the logic configuration of MAX4608ESE?
The MAX4608ESE contains two normally open (NO) SPST switches. When IN1 or IN2 is driven high (≥+2.4V), the corresponding NO terminal connects to its COM terminal; when low (≤+0.8V), the path remains open. This is explicitly defined in the General Description and Pin Description sections of the datasheet.
How does MAX4608ESE handle logic supply isolation?
MAX4608ESE uses a dedicated VL pin for logic supply, decoupled from analog V+ and V− rails. This allows independent biasing (e.g., +5V logic with ±15V analog), reducing digital switching noise coupling into sensitive analog paths - a key design feature verified in the Applications Information section.
Is MAX4608ESE pin-compatible with other variants in the MAX4607/08/09 family?
Yes, MAX4608ESE shares identical pinout and package (16-pin narrow SO) with MAX4607ESE and MAX4609ESE. All three variants differ only in switch configuration (NC/NO/mixed) and are functionally interchangeable at the board layout level - confirmed by identical Pin Configurations diagrams and Ordering Information tables.
