Product details
Overview
MAX4707EXT+T from Maxim Integrated is a normally open (NO), single-pole/single-throw (SPST) CMOS analog switch operating from a 1.8V to 5.5V single supply, delivering 3.5Ω maximum on-resistance and 0.9Ω on-resistance flatness at +2.7V, with 0.02µA quiescent current and −67dB off-isolation at 1MHz - deployed in battery-powered audio routing and low-voltage data-acquisition systems.
For engineers reviewing the MAX4707EXT+T datasheet, MAX4707EXT+T pinout, MAX4707EXT+T application, or MAX4707EXT+T equivalent, key selection criteria include guaranteed RON flatness over signal range, sub-nA leakage across −40°C to +85°C, SC70-6 package compatibility, and THD of 0.013% at 20Hz–20kHz for high-fidelity signal switching.
Technical Context
The MAX4707EXT+T implements a fully CMOS transmission-gate architecture optimized for low-voltage analog signal integrity, supporting bipolar input signals when biased with split supplies (e.g., V+ = 2V, GND = −2V). Its internal ESD diodes clamp analog terminals to V+ and GND, defining leakage behavior across temperature.
Switching is controlled by TTL/CMOS-compatible digital logic (VIH = 2.0V, VIL = 0.4V), with turn-on/turn-off times of 20ns/15ns (max) at V+ = 2.7V–3.6V, RL = 300Ω, CL = 35pF. Charge injection is limited to 5pC, enabling precision sample-and-hold operation without significant pedestal error.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 3.5Ω max at V+ = 2.7V, ensuring minimal voltage drop and signal attenuation in low-level analog paths |
| RON Flatness | 0.97Ω max over full analog signal range (0V to V+), preserving linearity in variable-amplitude applications |
| Off-Isolation | −67dB at 1MHz, suppressing crosstalk between active and inactive channels in multiplexed systems |
| THD | 0.013% at 2VP-P, 20Hz–20kHz, supporting high-fidelity audio signal routing without distortion |
| Supply Current | 0.02µA typical, enabling multi-year operation in coin-cell–powered portable instrumentation |
| Bandwidth | 190MHz −3dB, permitting RF-adjacent switching in wideband communications circuits |
| Leakage Current | ±2nA max (COM/NO/OFF) over −40°C to +85°C, maintaining accuracy in high-impedance sensor interfaces |
Pinout & Package
The MAX4707EXT+T is packaged in a 6-pin SC70 (SC70-6) surface-mount package with 0.65mm pitch, footprint-compatible with industry-standard SC70 layouts and reflow-process ready.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NO (Normally Open) | Analog output terminal disconnected from COM when IN = 0; connects to COM when IN = 1 |
| 2 | V+ | Positive supply rail (1.8V–5.5V); powers internal logic and switch core; must be applied before analog signals |
| 3 | IN | Digital control input (TTL/CMOS compatible); active-high logic enables NO-to-COM conduction |
| 4 | GND | Analog and digital ground reference; return path for supply current and signal currents |
| 5 | COM | Analog common terminal; bidirectional signal path shared between NO and internal switch element |
| 6 | N.C. | No internal connection; electrically isolated; no PCB trace required |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed RON flatness | 0.97Ω max ensures consistent gain and minimal harmonic generation across full analog input swing |
| Sub-nA leakage over temp | ±2nA max from −40°C to +85°C preserves DC accuracy in high-Z sensor front-ends and precision measurement |
| Low charge injection | 5pC enables stable sampling in 12-bit+ data acquisition without post-switch settling correction |
| Single-supply flexibility | 1.8V–5.5V operation supports direct integration with Li-ion, coin-cell, and 3.3V/5V system rails |
| Bipolar signal support | Accepts analog inputs beyond GND/V+ via internal ESD clamps, enabling ±1V signals with V+ = 2V, GND = −2V |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG801BRMZ-REEL | 2.5Ω RON max at 3V, 0.5Ω flatness, but higher 10nA leakage at +85°C | Suitable for lower-RON priority designs where leakage tolerance >5nA is acceptable | Select when tighter RON spec outweighs leakage sensitivity in moderate-temp environments |
| TS5A23157DCUR | 0.9Ω RON max at 3V, but only −45dB off-isolation at 1MHz and no guaranteed flatness spec | Better for cost-sensitive, high-speed digital signal routing vs. precision analog paths | Prefer for general-purpose I/O switching where THD and isolation are secondary to RON and price |
Compared with ADG801BRMZ-REEL and TS5A23157DCUR, the MAX4707EXT+T provides superior off-isolation and guaranteed RON flatness critical for precision analog multiplexing, while maintaining ultra-low leakage and THD - making it optimal for battery-powered instrumentation and high-fidelity audio where signal fidelity dominates.

FAQ
What is the maximum supply voltage rating for the MAX4707EXT+T?
The MAX4707EXT+T has an absolute maximum supply voltage (V+) rating of +6V, but its specified operational range is 1.8V to 5.5V. Operation above 5.5V voids guaranteed performance and risks permanent damage per the Absolute Maximum Ratings table. For reliable function, keep V+ within 1.8V–5.5V, and always apply V+ before analog signals to prevent ESD diode conduction-induced stress on the MAX4707EXT+T.
Does the MAX4707EXT+T support bipolar analog signals?
Yes, the MAX4707EXT+T supports bipolar analog signals when powered from split supplies - for example, with V+ = 2V and GND = −2V, it accepts ±1VP-P inputs. This capability arises from internal ESD protection diodes clamping analog terminals (NO, COM) to both V+ and GND. However, signal excursions beyond these rails forward-bias those diodes, so external current limiting is required to stay within ±300mA peak current limits. The MAX4707EXT+T datasheet confirms this behavior in the Applications Information section.
What is the guaranteed on-resistance flatness specification for the MAX4707EXT+T?
The MAX4707EXT+T guarantees on-resistance flatness (RFLAT(ON)) of 0.97Ω maximum over the full analog signal range (0V to V+) at V+ = 2.7V and across the full operating temperature range (−40°C to +85°C). This parameter - defined as the difference between max and min RON - ensures minimal gain variation across input voltage, critical for linearity in precision measurement. At +25°C, typical flatness is 0.1Ω, but design margin must use the 0.97Ω worst-case value from the Electrical Characteristics table.
How does the MAX4707EXT+T achieve ultra-low quiescent current?
The MAX4707EXT+T achieves 0.02µA typical quiescent current through deep-submicron CMOS process optimization and static logic design that minimizes leakage paths in the control circuitry and transmission gate. This current remains stable across temperature and supply voltage, with a maximum of 1µA over −40°C to +85°C per the Electrical Characteristics table. The ultra-low I+ enables multi-year operation in energy-harvesting and coin-cell–powered devices - a key differentiator confirmed in the General Description and Typical Operating Characteristics (Figure toc07) of the MAX4707EXT+T datasheet.
Is the MAX4707EXT+T pin-compatible with other variants in the MAX4706/MAX4707 family?
The MAX4707EXT+T (SC70-6) shares identical pinout with the MAX4706EXT-T (SC70-6) and MAX4707ELT-T (µDFN-6), but differs from the 5-pin SC70 versions (MAX4707EXK-T) which omit Pin 6 (N.C.). While the SC70-6 variants are functionally and pinout-compatible, the µDFN-6 variant requires layout adaptation due to different thermal pad and footprint dimensions. No cross-package pin-to-pin compatibility exists between SC70-5 and SC70-6 packages - the MAX4707EXT+T requires the 6-pin layout per its Pin Description table and SC70-6 mechanical drawing.
