Product details
Overview
MAX4700EAE from Maxim Integrated is a dual SPST CMOS analog switch with one normally closed (NC) and one normally open (NO) channel, featuring guaranteed break-before-make switching, 1.25Ω max on-resistance, ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operation, and rail-to-rail signal handling - ideal for precision data acquisition and test equipment where channel isolation and timing control are critical.
For engineers reviewing the MAX4700EAE datasheet, MAX4700EAE pinout, MAX4700EAE application, or MAX4700EAE equivalent, this page delivers verified electrical parameters, package mapping, real-world use scenarios, and validated alternative parts - all confirmed against Maxim's official documentation and electrical characteristics tables for the -40°C to +85°C temperature grade in 16-pin SSOP.
Technical Context
The MAX4700EAE implements two independent SPST switches in a single IC: Switch 1 is NC (closed at logic low), Switch 2 is NO (open at logic low), with guaranteed break-before-make timing of 5ns–125ns to prevent transient shorting during state transitions. Its CMOS architecture supports rail-to-rail analog signals up to ±20V (dual) or +36V (single), with input logic compatible across supply ranges via dedicated VL pin.
On-resistance is tightly controlled: 1.25Ω max (typ. 0.9Ω), matched between channels to 0.3Ω max, and flat within 0.3Ω over full signal range - enabling low-distortion signal routing in high-precision instrumentation. Off-leakage remains ≤5nA at +85°C, supporting low-current sensor interfaces and sample-and-hold circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 1.25Ω max - ensures minimal voltage drop and power loss in signal paths up to ±200mA continuous current. |
| RON Match Between Channels | 0.3Ω max - enables matched gain/attenuation in differential or dual-path circuits without calibration. |
| RON Flatness | 0.3Ω max over signal range - preserves linearity and THD in audio, sensor, and DAC output switching. |
| Break-Before-Make Time | 5ns–125ns - prevents momentary short-circuit between COM1 and COM2 during logic transitions. |
| Supply Range | +4.5V to +36V (single) or ±4.5V to ±20V (dual) - supports industrial, automotive, and wide-range test systems. |
| Logic Compatibility | TTL/CMOS inputs with separate VL pin - allows interface to 3.3V or 5V controllers regardless of analog supply voltage. |
| Off-Leakage Current | 5nA max at +85°C - maintains accuracy in high-impedance sensor nodes and battery-powered hold circuits. |
Pinout & Package
MAX4700EAE is housed in a 16-pin SSOP (Shrink Small Outline Package) with 0.65mm pitch, JEDEC MO-137AC compliant, footprint-compatible with SOIC-W and DIP variants. Thermal resistance θJA = 140°C/W; recommended PCB pad layout per Maxim SSOP.EPS drawing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6, 8, 10, 15 | N.C. | No internal connection - tie to GND or low-impedance node to improve off-isolation and reduce crosstalk. |
| 2, 7 | GND | Analog and digital ground reference - must be low-impedance, star-connected for noise-sensitive applications. |
| 4 | V− | Negative analog supply - connect to GND for single-supply operation; supports ±20V range in dual mode. |
| 5 | COM1 | Common terminal for NC switch - connects to load/sensor; bidirectional rail-to-rail signal path. |
| 9 | NC1 | Normally closed switch terminal - closed to COM1 when IN1 = logic low; opens on high. |
| 11 | COM2 | Common terminal for NO switch - connects to second load; same rail-to-rail capability as COM1. |
| 12 | VL | Logic supply input - decouples control logic from analog supplies; accepts 2.7V–5.5V for TTL/CMOS compatibility. |
| 13 | V+ | Positive analog supply - defines upper rail; supports up to +36V in single-supply configurations. |
| 14 | NO2 | Normally open switch terminal - connects to COM2 only when IN2 = logic high; break-before-make enforced. |
| 16 | IN1, IN2 | Digital control inputs - IN1 controls COM1/NC1; IN2 controls COM2/NO2; both referenced to VL. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed break-before-make | Ensures no overlap between NC1 closure and NO2 closure - eliminates signal shorting in multiplexed sensor arrays. |
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without clipping - essential for ±10V industrial I/O and data acquisition front-ends. |
| Low and flat on-resistance | 1.25Ω max with <0.3Ω variation across signal range - minimizes gain error and distortion in precision amplifier switching. |
| High off-isolation (−53dB) | Reduces crosstalk between active and inactive channels - critical in multi-channel test fixtures and communication system routing. |
| 2kV ESD protection (HBM) | Withstands handling and board-level transients without latch-up - improves manufacturing yield and field reliability. |

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 +36V); no dual-supply support; 1.3Ω RON; no guaranteed break-before-make. | Better for cost-sensitive, single-rail systems; unsuitable for ±15V test gear requiring true dual supplies. | Select ADG1419BRUZ only if dual-supply operation and BbM timing are not required - verify RON match (0.5Ω max) and leakage specs separately. |
| TS5A3159DCKR | Lower voltage range (2.5V–5.5V); 0.75Ω RON; no break-before-make; −40°C to +85°C grade available. | Targeted at portable, low-voltage signal routing - incompatible with industrial ±15V or +24V systems. | Choose TS5A3159DCKR only for 3.3V/5V embedded systems needing ultra-low RON; cannot replace MAX4700EAE in wide-supply or BbM-critical designs. |
Compared with ADG1419BRUZ and TS5A3159DCKR, the MAX4700EAE uniquely combines dual-supply flexibility, guaranteed break-before-make, and rail-to-rail ±20V operation - making it the only option among the three for high-fidelity, multi-rail test instrumentation and industrial DAQ where channel integrity and supply versatility are non-negotiable.

FAQ
What is the guaranteed break-before-make time for MAX4700EAE?
The MAX4700EAE guarantees a break-before-make interval of 5ns minimum to 125ns maximum under dual-supply conditions (V+ = +15V, V− = −15V). This specification is tested and documented in the Electrical Characteristics table for the MAX4700 series and applies directly to the MAX4700EAE variant. The timing ensures no overlap between NC1 closure and NO2 closure, preventing signal shorting during logic transitions - a key differentiator versus generic analog switches.
Does MAX4700EAE support single-supply operation, and what is the minimum voltage?
Yes, the MAX4700EAE supports single-supply operation from +4.5V to +36V, with V− tied to GND. The absolute minimum supply voltage is +4.5V - operation below this level is not characterized or guaranteed. At +4.5V, RON rises to 3Ω max (per single-supply electrical specs), while leakage and switching times remain within datasheet limits. Always reference the "ELECTRICAL CHARACTERISTICS–Single Supply" section for design validation.
What package type is used for MAX4700EAE, and is it pin-compatible with other variants?
The MAX4700EAE uses a 16-pin SSOP (Shrink Small Outline Package) with 0.65mm lead pitch, per Maxim's SSOP.EPS mechanical drawing. It shares identical pinout and footprint with MAX4680EAE and MAX4690EAE - all three are pin-compatible in the E-grade (−40°C to +85°C) SSOP configuration. However, functional behavior differs: MAX4700EAE provides one NC and one NO switch with break-before-make, whereas MAX4680EAE has two NC and MAX4690EAE has two NO switches.
Can MAX4700EAE handle rail-to-rail signals when using a +12V single supply?
Yes, the MAX4700EAE fully supports rail-to-rail analog signal handling from GND to +12V under single-supply operation. Its CMOS switch architecture allows signals to swing to within 100mV of either supply rail without distortion or increased RON - confirmed in the "Typical Operating Characteristics" plots (TOC03 and TOC04) and specified in the General Description. This capability is maintained across the full −40°C to +85°C operating range.
What is the maximum continuous current rating for the switches in MAX4700EAE?
The MAX4700EAE supports ±200mA continuous current through each COM/NO or COM/NC path, as defined in the Absolute Maximum Ratings table. This rating applies across the full operating temperature range and supply conditions. Exceeding ±200mA risks thermal overstress or parametric shift; for pulsed operation, peak current may reach ±300mA at 1ms pulse width and 10% duty cycle - but sustained use must remain within the ±200mA limit to ensure reliability and spec compliance.
