Product details
Overview
MAX4517ESA from Maxim Integrated is a normally closed (NC), single-pole/single-throw (SPST), dual-supply CMOS analog switch with 20Ω on-resistance at ±5V, 1nA off-leakage at +25°C, and rail-to-rail signal handling capability-designed for low-voltage audio routing and battery-powered data-acquisition systems.
For engineers reviewing the MAX4517ESA datasheet, MAX4517ESA pinout, MAX4517ESA application, or MAX4517ESA equivalent, key selection criteria include guaranteed NC switching behavior, ±1V to ±6V dual-supply operation, low charge injection (20pC max), fast tON/tOFF (100ns/75ns), and SOT23-5 package compatibility with space-constrained portable designs.
Technical Context
The MAX4517ESA implements a fully differential CMOS transmission gate architecture with independent V+ and V− supply pins driving both analog signal paths and internal logic-level translators. Its NC configuration ensures default continuity between COM and NC terminals when IN is low.
Internal ESD diodes clamp analog pins to V+ and V−, making leakage current highly dependent on signal voltage relative to supplies-resulting in temperature- and voltage-dependent off-leakage (1nA @ +25°C, 20nA @ +85°C) and on-leakage (2nA @ +25°C, 40nA @ +85°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Normally closed (NC) SPST analog switch-ensures default signal path continuity without control activation. |
| On-Resistance (RON) | 20Ω max at ±5V-enables minimal signal attenuation in precision low-voltage sensor or audio paths. |
| Off-Leakage Current | 1nA max at +25°C-preserves signal integrity in high-impedance measurement nodes. |
| Charge Injection | 20pC max-limits voltage glitch on switched capacitive loads (e.g., ADC sample-and-hold inputs). |
| Switching Speed | tON = 100ns, tOFF = 75ns-supports multiplexing of signals up to ~3MHz without significant timing skew. |
| Supply Range | ±1V to ±6V dual supply-allows operation from low-power Li-ion cells (±2.5V) up to industrial ±5V rails. |
| Analog Signal Range | Rail-to-rail (V− to V+)-permits full-swing AC/DC signal switching without clipping. |
Pinout & Package
SOT23-5 surface-mount package (3.0mm × 1.75mm × 1.3mm body height), RoHS-compliant, tape-and-reel compatible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Digital control input | CMOS-compatible logic input referenced to V+; LOW enables NC path (COM↔NC), HIGH opens it. |
| 2 - NC | Normally closed analog terminal | Internally connected to COM when IN = LOW; electrically interchangeable with NO/COM per datasheet note. |
| 3 - V− | Negative supply rail | Powers analog switches and logic; sets lower bound of rail-to-rail analog range; clamps ESD diodes. |
| 4 - V+ | Positive supply rail | Powers analog switches and logic; sets upper bound of rail-to-rail analog range; clamps ESD diodes. |
| 5 - COM | Common analog terminal | Shared node for NC (default) and NO (when enabled); bidirectional signal path with matched RON. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed NC functionality | Ensures fail-safe signal continuity in power-loss or unpowered states-critical for safety-critical monitoring paths. |
| Low on-resistance flatness (6Ω) | Maintains consistent gain/attenuation across full analog input range (±4.5V), reducing distortion in AC-coupled audio. |
| 100% tested hot-temperature leakage | Off-leakage validated at +85°C (20nA max) ensures reliability in automotive or industrial ambient conditions. |
| CMOS logic compatibility | Accepts standard CMOS thresholds (VIL = V+ − 3.5V, VIH = V+ − 1.5V) without level-shifting circuitry. |
| Low total harmonic distortion | <0.01% THD at 1kHz-preserves fidelity in line-level audio routing applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4517EUK | Same die, SOT23-5 package, but rated for −40°C to +85°C industrial temp range (vs. ESA's −40°C to +85°C-identical spec; ESA and EUK share same temp grade per ordering table). | No functional difference; EUK denotes tape-and-reel packaging variant-identical electrical performance and pinout. | Select MAX4517EUK for automated SMT assembly requiring reel-fed feeders; MAX4517ESA is tube-packaged for prototyping or low-volume hand-soldering. |
| ADG1219BRMZ | NC SPST switch with higher RON (125Ω typ), wider supply (±5V to ±16.5V), and higher leakage (200pA typ @ +25°C). | Better suited for high-voltage industrial I/O isolation; unsuitable for low-leakage sensor muxing due to 200× higher off-current. | Choose ADG1219BRMZ only when >±10V operation is required; MAX4517ESA remains superior for ≤±6V, low-leakage, low-RON portable applications. |
Compared with MAX4517EUK, MAX4517ESA offers identical electrical specs but different packaging-tube vs. tape-and-reel-while ADG1219BRMZ trades low leakage and RON for extended voltage range, making it non-interchangeable in precision low-voltage designs.

FAQ
What is the operating temperature range for the MAX4517ESA?
The MAX4517ESA is specified for −40°C to +85°C operation, matching the "E" grade in Maxim's ordering nomenclature. This industrial temperature range is confirmed in the Ordering Information table, where MAX4517ESA is explicitly listed under the −40°C to +85°C column alongside MAX4517EUK and MAX4517ESA. All electrical characteristics-including on-resistance, leakage, and switching speed-are guaranteed across this full range.
Is the MAX4517ESA pin-compatible with the MAX4516ESA?
Yes, the MAX4517ESA and MAX4516ESA share identical SOT23-5 pinouts and package dimensions, differing only in internal switch configuration: MAX4517ESA is normally closed (NC), while MAX4516ESA is normally open (NO). Both use the same IN, COM, V+, V−, and NC/NO pin assignments-allowing PCB reuse when switching between fail-open and fail-closed behavior without layout changes.
Does the MAX4517ESA support single-supply operation?
The MAX4517ESA is designed for dual-supply operation (±1V to ±6V) and does not support true single-supply use. While it may function with a single +2V to +12V rail, its logic thresholds are referenced to V+, and exceeding V+ or V− on analog pins risks ESD diode conduction. For single-supply applications, Maxim recommends the pin-compatible MAX4514/MAX4515 series instead.
What is the maximum allowable analog signal voltage for the MAX4517ESA?
The MAX4517ESA supports rail-to-rail analog signals from V− to V+. With ±5V supplies, the absolute maximum analog input is −5V to +5V. Exceeding V+ or V− triggers internal ESD diodes, limiting voltage compliance to the supply rails. The Absolute Maximum Ratings specify that any terminal voltage must stay within −0.3V to (V+ + 0.3V), reinforcing strict adherence to the V−/V+ bounds for reliable operation.
How is the logic threshold defined for the MAX4517ESA's IN pin?
The MAX4517ESA's IN pin uses CMOS-compatible logic thresholds referenced to V+: VIH = V+ − 1.5V (minimum) and VIL = V+ − 3.5V (maximum) for V+ between +3V and +6V. At V+ = +2V, the threshold approximates 0.6V. This design eliminates need for external level shifters when driven by CMOS logic sharing the same V+ rail-but prohibits direct connection to +5V TTL sources when V+ < +3.5V to avoid violating absolute maximum ratings.
