Product details
Overview
MAX4600CAE+ from Maxim Integrated is a dual SPST CMOS analog switch with one normally closed (NC) and one normally open (NO) channel, designed for rail-to-rail signal routing in precision analog systems. It delivers 1.25Ω max on-resistance, 0.25Ω max RON match between channels, and 0.3Ω max RON flatness over ±10V signal range. It operates from +4.5V to +36V single supply or ±4.5V to ±20V dual supplies and supports TTL/CMOS logic inputs - ideal for reed relay replacement in automated test equipment.
For engineers reviewing the MAX4600CAE+ datasheet, MAX4600CAE+ pinout, MAX4600CAE+ application, or MAX4600CAE+ equivalent, key selection criteria include verified NC/NO dual-SPST topology, guaranteed RON matching and flatness, rail-to-rail analog handling up to ±10V, ESD protection >2kV, and SSOP-16 package compatibility with industrial temperature range (0°C to +70°C).
Technical Context
The MAX4600CAE+ integrates two independent CMOS transmission gates: Switch 1 is NC (closed when IN1 = 0), Switch 2 is NO (closed when IN2 = 1), enabling complementary signal path control. Its architecture uses charge-pump-assisted level shifting to maintain low RON across full analog voltage range without external biasing.
It features separate analog supply pins (V+, V−), logic supply pin (VL), and isolated ground (GND), supporting true dual-supply operation while maintaining <2.5nA off-leakage at +85°C and <1pC typical charge injection - critical for sample-and-hold and multiplexer applications requiring minimal signal disturbance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 1.25Ω max - ensures minimal signal attenuation and voltage drop in precision analog paths |
| RON Match Between Channels | 0.25Ω max - enables matched gain/attenuation in differential or dual-path circuits |
| RON Flatness | 0.3Ω max over ±10V - maintains consistent channel resistance across full signal swing |
| Off-Leakage Current | 2.5nA max at +85°C - preserves accuracy in high-impedance sensor interfaces and integrators |
| Supply Range | +4.5V to +36V single or ±4.5V to ±20V dual - supports wide industrial and test-equipment power rails |
| Logic Compatibility | TTL/CMOS thresholds (+0.8V low / +2.4V high) - interoperable with standard digital controllers without level shifters |
| ESD Protection | >2kV per Method 3015.7 - withstands handling and board-level electrostatic discharge |
Pinout & Package
MAX4600CAE+ is housed in a 16-pin SSOP (Shrink Small Outline Package) with 0.65mm lead pitch, 5.3mm body width, and JEDEC MO-150 compliance. The package supports surface-mount assembly and provides thermal performance suitable for industrial ambient conditions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6, 8, 10, 15 | N.C. | No internal connection; recommended to tie to GND for improved isolation |
| 2, 7 | GND | Analog and digital ground reference common to all circuit domains |
| 4 | V− | Negative analog supply input; connect to GND for single-supply operation |
| 5 | GND | Dedicated ground pin - electrically identical to Pin 2/7 but placed for layout decoupling |
| 9, 16 | NC1, NC2 | Normally closed analog terminals - conduct to COMx when respective INx = 0 |
| 11, 14 | COM1, COM2 | Common analog ports - bidirectional signal interface for both NC and NO paths |
| 12 | VL | Logic supply input - powers internal level-shifting circuitry; typically +5V |
| 13 | V+ | Positive analog supply input - defines upper rail for analog signal range |
| 1, 3, 6, 8, 10, 15 | N.C. | No internal connection; recommended to tie to GND for improved isolation |
| IN1, IN2 | Logic-Control Inputs | Digital control signals: IN1 controls NC1/COM1; IN2 controls NO2/COM2 (active-high for NO, active-low for NC) |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports continuous ±10V differential signals without clipping or distortion - essential for data acquisition front-ends |
| Guaranteed RON match (0.25Ω max) | Enables precise amplitude tracking in dual-channel instrumentation, such as balanced line drivers or differential ADC inputs |
| Low charge injection (40pC typ) | Minimizes voltage glitch on sampled nodes - critical for low-error sample-and-hold and switched-capacitor filters |
| High off-isolation (−53dB typ) | Reduces crosstalk between active and inactive channels in multi-signal routing applications like PBX switching matrices |

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 | Single-supply only (±5V to ±22V dual not supported); 0.9Ω RON; requires VL = V+ for level shift | Lacks native dual-supply support - unsuitable for legacy ±15V test gear without redesign | Prefer when system uses only single-ended supplies and demands lowest possible RON |
| TS5A3159DCKR | Lower voltage rating (+1.65V to +5.5V); 0.75Ω RON; no NC/NO asymmetry - both switches are NO | Cannot replicate MAX4600CAE+'s mixed NC/NO functionality for fail-safe or polarity-switching roles | Select only for low-voltage portable designs where NC behavior is unnecessary |
Compared with ADG1419BRUZ and TS5A3159DCKR, the MAX4600CAE+ uniquely combines NC/NO duality, wide dual-supply operation, and guaranteed RON matching - making it irreplaceable in applications requiring fail-safe signal continuity or bipolar test stimulus routing.

FAQ
What is the operating temperature range for MAX4600CAE+?
The MAX4600CAE+ is specified for operation from 0°C to +70°C. This commercial-grade temperature range is validated across all electrical parameters in the datasheet, including RON, leakage, and switching times. The "CAE" suffix explicitly denotes this temperature grade, distinguishing it from the extended −40°C to +85°C "EAE" variant. For designs requiring wider thermal margins, MAX4600EAE+ must be selected instead.
Does MAX4600CAE+ support true dual-supply operation with independent V+ and V−?
Yes, MAX4600CAE+ fully supports true dual-supply operation with V+ and V− independently biased - for example, +15V and −15V - enabling rail-to-rail analog signal handling from −15V to +15V. The device maintains 1.25Ω max RON and <2.5nA off-leakage under these conditions. Single-supply mode is also supported by tying V− to GND, with V+ ranging from +4.5V to +36V.
How is the NC/NO configuration implemented in MAX4600CAE+?
In MAX4600CAE+, Switch 1 (COM1/NC1) is normally closed: it conducts when IN1 = 0V and opens when IN1 = logic high. Switch 2 (COM2/NO2) is normally open: it conducts only when IN2 = logic high. This asymmetric configuration is hardwired in silicon and cannot be reversed. The truth table is explicitly defined in the datasheet's "Pin Configurations" section and verified across all production lots.
Can MAX4600CAE+ drive ±10V signals without distortion?
Yes, MAX4600CAE+ guarantees rail-to-rail analog signal handling up to ±10V with 0.3Ω max RON flatness across that full range - meaning resistance variation is held to ≤0.3Ω regardless of signal voltage. This ensures minimal THD and amplitude error in audio, sensor, and instrumentation paths. Performance is characterized and tested at ±10V with V+ = ±15V and confirmed in Figure TOC02 of the datasheet.
What is the maximum continuous current rating for MAX4600CAE+ switches?
The MAX4600CAE+ supports ±200mA continuous current through its COM, NO, and NC terminals - verified across temperature and supply conditions. This rating applies to both channels simultaneously and is limited by package thermal dissipation (571mW at +70°C ambient for SSOP-16). Peak pulsed current is ±300mA at 1ms/10% duty cycle, enabling brief overload tolerance during system transients.
