Product details
Overview
MAX4680CAE+ from Maxim Integrated is a dual SPST CMOS analog switch with two normally closed (NC) channels, designed for rail-to-rail signal routing in precision analog systems. It delivers 1.25Ω max on-resistance, 0.3Ω max RON match between channels, and 5nA max off-leakage at +85°C, enabling low-distortion switching in data acquisition and test equipment.
For engineers reviewing the MAX4680CAE+ datasheet, MAX4680CAE+ pinout, MAX4680CAE+ application, or MAX4680CAE+ equivalent, key selection criteria include guaranteed NC configuration, ±4.5V to ±20V dual-supply operation, TTL/CMOS-compatible logic inputs with separate VL pin, and break-before-make exclusion (as MAX4680 lacks this feature).
Technical Context
The MAX4680CAE+ implements a dual-channel, normally closed analog switch architecture using complementary MOSFET pairs per channel, supporting bidirectional rail-to-rail analog signals from V− to V+. Its control logic accepts TTL/CMOS levels independent of analog supply voltage via dedicated VL pin, ensuring compatibility across full ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply ranges.
On-resistance flatness is guaranteed ≤0.3Ω over the full specified signal range, and channel-to-channel RON matching is tightly controlled to ≤0.3Ω max-critical for differential signal integrity and gain-matching in instrumentation front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 1.25Ω max - ensures minimal signal attenuation and voltage drop in low-level analog paths |
| RON Match (ΔRON) | 0.3Ω max - enables matched gain/attenuation in dual-channel differential or multiplexed circuits |
| RON Flatness | 0.3Ω max over signal range - preserves linearity and THD performance across full input swing |
| Off-Leakage Current | 5nA max at +85°C - prevents DC error accumulation in high-impedance sample-and-hold or sensor interfaces |
| Supply Range | +4.5V to +36V single or ±4.5V to ±20V dual - supports industrial, automotive, and wide-range test equipment rails |
| Logic Compatibility | TTL/CMOS inputs with separate VL pin - decouples logic threshold from analog supply, simplifying mixed-voltage system design |
| ESD Protection | >2kV per Method 3015.7 - enhances robustness in handling and board-level ESD events |
Pinout & Package
MAX4680CAE+ is housed in a 16-pin SSOP (Shrink Small Outline Package) with 0.65mm lead pitch, optimized for compact PCB layouts while maintaining thermal and electrical performance.
| 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 isolation |
| 2, 7 | GND | Analog and digital ground reference; requires low-impedance return path |
| 4 | V− | Negative analog supply input; connect to GND for single-supply operation |
| 5 | COM1 | Channel 1 common terminal - bidirectional analog I/O node |
| 9, 16 | NC1, NC2 | Normally closed switch terminals - conduct to COM when IN = logic low |
| 11, 14 | COM2 | Channel 2 common terminal - independent bidirectional analog I/O node |
| 12 | VL | Dedicated logic supply input - sets TTL/CMOS input thresholds independently of V+/V− |
| 13 | V+ | Positive analog supply input - defines upper rail for rail-to-rail signal handling |
Key Features
| Feature | Design Value |
|---|---|
| Dual NC configuration | Ensures default-closed signal path for fail-safe operation in safety-critical monitoring circuits |
| Rail-to-rail analog signal handling | Supports full V− to V+ input/output swing without clipping - essential for ±15V op-amp interfaces |
| Guaranteed RON flatness ≤0.3Ω | Maintains consistent gain and phase response across signal amplitude - critical for audio and measurement accuracy |
| Separate VL logic supply pin | Enables 3.3V or 5V logic control while operating from ±15V analog rails - eliminates level-shifter complexity |
| Low charge injection (±60pC) | Minimizes voltage glitch on sampled nodes - improves settling time in precision ADC front-ends |
Applications
| Reed Relay Replacement | Data Acquisition Systems |
|---|---|
Use Scenario: Replacing electromechanical relays in automated test fixtures where cycle life, speed, and size are constrained. IC Role / Device Role / Timing Role: Dual NC analog switch providing fail-safe closed-path signal routing until de-energized. Use Value: Eliminates relay wear-out, reduces actuation time from ms to ns, and cuts board area by >70% versus equivalent DPDT relays. |
Use Scenario: Multiplexing multiple sensor outputs into a shared ADC channel in industrial PLC modules. IC Role / Device Role / Timing Role: Low-RON, matched dual switch enabling synchronized sampling of differential sensor pairs. Use Value: 0.3Ω RON match preserves common-mode rejection; 5nA leakage prevents offset drift in high-Z thermocouple inputs. |
| Test Equipment Signal Routing | Sample-and-Hold Circuits |
Use Scenario: Configurable signal path selection in benchtop multimeters and parameter analyzers requiring low crosstalk and high isolation. IC Role / Device Role / Timing Role: Dual SPST NC switch isolating DUT connections during calibration or protection sequencing. Use Value: −65dB crosstalk and −53dB off-isolation prevent measurement contamination between adjacent channels. |
Use Scenario: Holding capacitor charging path in precision integrators and peak detectors used in power quality analyzers. IC Role / Device Role / Timing Role: Low-charge-injection NC switch controlling hold capacitor connection to input source. Use Value: ±60pC charge injection limits hold-step error to <1LSB in 16-bit systems with 10nF hold capacitors. |
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 |
|---|---|---|---|
| MAX4690CAE+ | Dual NO (normally open) configuration vs. MAX4680CAE+'s dual NC; identical RON, leakage, and supply specs | Suitable where default-open safety state is required (e.g., power-off signal isolation) | Select MAX4690CAE+ when circuit must be open-circuit at power-up or logic-low control. |
| ADG1419BRUZ | Single-supply only (+5V to +36V); 1.3Ω RON; no separate VL pin; 16-TSSOP package | Lacks dual-supply flexibility and logic supply independence - limits use in ±15V instrumentation | Choose ADG1419BRUZ only for cost-sensitive, single-rail designs where VL decoupling is unnecessary. |
Compared with MAX4690CAE+, MAX4680CAE+ provides fail-safe continuity in unpowered or logic-low states; compared with ADG1419BRUZ, it offers superior dual-supply operation and isolated logic threshold control-key for mixed-signal test and measurement systems.

FAQ
What is the maximum allowable supply voltage for MAX4680CAE+?
The MAX4680CAE+ supports absolute maximum analog supply ratings of V+ to GND = −0.3V to +44V and V− to GND = +0.3V to −44V. For reliable operation, use within the recommended ranges: +4.5V to +36V single supply or ±4.5V to ±20V dual supplies. Exceeding these may cause permanent damage, as confirmed in the Absolute Maximum Ratings table.
Does MAX4680CAE+ support break-before-make switching?
No, MAX4680CAE+ does not feature break-before-make switching. That functionality is exclusive to the MAX4700 variant (one NC + one NO channel). The MAX4680CAE+ implements two independent normally closed switches with no guaranteed overlap or timing coordination between channels - verified in the Functional Diagrams and Truth Tables section.
What is the purpose of the VL pin on MAX4680CAE+?
The VL pin on MAX4680CAE+ provides a dedicated logic supply reference that sets TTL/CMOS input thresholds independently of the analog V+ and V− supplies. This allows clean 3.3V or 5V logic control even when operating from ±15V analog rails - a key differentiator confirmed in the Electrical Characteristics tables under "Logic Input Voltage High/Low" parameters.
Can MAX4680CAE+ handle bipolar analog signals?
Yes, MAX4680CAE+ fully supports bipolar analog signals from V− to V+ when operated from dual supplies (e.g., ±15V), or from GND to V+ in single-supply mode. Its rail-to-rail capability is explicitly validated across the full signal range in both configurations, with RON flatness ≤0.3Ω and leakage ≤5nA - per the Typical Operating Characteristics graphs and Electrical Characteristics tables.
Is MAX4680CAE+ pin-compatible with other variants in the MAX4680/MAX4690/MAX4700 family?
Yes, MAX4680CAE+, MAX4690CAE+, and MAX4700CAE+ share identical 16-pin SSOP footprints and pinouts - confirmed in the Pin Configurations diagrams. However, functional behavior differs: MAX4680CAE+ is dual NC, MAX4690CAE+ is dual NO, and MAX46700CAE+ is mixed NC/NO with break-before-make. Swapping requires logic inversion and system-level validation.
