Product details
Overview
MAX4516ESA from Maxim Integrated is a single-pole/single-throw (SPST), normally-open (NO), CMOS analog switch optimized for low-voltage dual-supply operation. It delivers 20Ω on-resistance at ±5V supplies, supports rail-to-rail analog signal switching, and exhibits only 1nA off-leakage at +25°C - enabling precision signal routing in battery-powered audio and data-acquisition systems.
For engineers reviewing the MAX4516ESA datasheet, MAX4516ESA pinout, MAX4516ESA application, or MAX4516ESA equivalent, key selection criteria include guaranteed low on-resistance flatness (6Ω), fast switching (tON = 100ns), CMOS-compatible logic referenced to V+, and SOT23-5 package compatibility with space-constrained portable designs.
Technical Context
The MAX4516ESA uses a dual-supply CMOS architecture with independent V+ and V− pins that define both analog signal range (rail-to-rail) and internal gate drive levels. Its logic input is referenced solely to V+, eliminating ground dependency and supporting operation across ±1V to ±6V supply ranges.
Internal ESD diodes clamp analog terminals to V+ and V−, making leakage current highly dependent on signal voltage relative to supply rails. The device achieves low charge injection (20pC max) and high off-isolation (−86dB at 100kHz), critical for maintaining signal integrity in multiplexed sensor and audio paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 20Ω max at ±5V - ensures minimal signal attenuation and gain error in precision analog paths |
| On-Resistance Flatness | 6Ω max - maintains consistent channel impedance across full analog signal range (±4.5V) |
| Off-Leakage Current | 1nA max at +25°C - preserves accuracy in high-impedance sensor interfaces and sample-hold circuits |
| Charge Injection | 20pC max - limits voltage glitch on switched capacitor nodes, critical for ADC front-ends |
| Switching Speed | tON = 100ns, tOFF = 75ns - supports >1MHz multiplexing without timing bottlenecks |
| Analog Signal Range | Rail-to-rail (V− to V+) - enables full utilization of supply headroom in low-voltage systems |
| Logic Compatibility | CMOS-level input referenced to V+ - eliminates need for level-shifting when V+ = +3V to +5V |
Pinout & Package
MAX4516ESA is housed in a 5-pin SOT23-5 surface-mount package (JEDEC MO-178AA), footprint dimensions 2.80 × 2.60 × 1.30 mm, with gull-wing leads and thermal pad not connected internally.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Digital control input | CMOS-compatible logic signal referenced to V+; HIGH enables switch conduction (NO path closed) |
| 2 - NO | Normally-open analog terminal | Connects to COM only when IN = HIGH; bidirectional signal path with identical RON in either direction |
| 3 - V− | Negative supply rail | Bias source for analog switches and internal logic; sets lower bound of rail-to-rail analog range |
| 4 - V+ | Positive supply rail | Bias source for analog switches and internal logic; sets upper bound of rail-to-rail analog range |
| 5 - COM | Analog common terminal | Shared node for NO connection; serves as input or output depending on system topology |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed low on-resistance | 20Ω max at ±5V - reduces insertion loss and distortion in audio and instrumentation signal chains |
| Ultra-low off-leakage | 1nA at +25°C - prevents DC error accumulation in high-Z sensor amplifiers and integrators |
| Low charge injection | 20pC max - minimizes settling time and residual offset in switched-capacitor filters and sample-hold stages |
| Fast, asymmetric switching | tON > tOFF at ±5V - enables precise timing control in synchronous sampling applications |
| Dual-supply flexibility | Operates from ±1V to ±6V - supports wide range of portable and industrial supply architectures without redesign |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4514ESA | Single-supply operation (+2V to +12V); no V− pin; logic threshold referenced to VDD | Designed for systems lacking negative rail; unsuitable for true bipolar signal routing | Select MAX4514ESA only when V− is unavailable and analog signals remain within 0V to VDD |
| ADG1219BRMZ | Higher RON (120Ω typ), wider temp range (−40°C to +125°C), 1.8V logic compatible | Targeted at industrial automation where extended temperature stability outweighs on-resistance penalty | Choose ADG1219BRMZ when operating beyond +85°C or interfacing with 1.8V microcontrollers |
Compared with MAX4514ESA and ADG1219BRMZ, the MAX4516ESA uniquely balances ultra-low RON, sub-nA leakage, and dual-supply rail-to-rail capability - making it optimal for portable, precision analog multiplexing where supply headroom and signal fidelity are constrained.

FAQ
What is the maximum dual-supply voltage range supported by the MAX4516ESA?
The MAX4516ESA operates continuously with dual supplies from ±1V up to ±6V. It is fully tested and guaranteed over this range, though electrical specifications such as on-resistance and leakage are characterized at ±5V. Operation outside ±6V violates absolute maximum ratings and risks permanent damage.
Does the MAX4516ESA require a ground connection?
No, the MAX4516ESA has no ground pin. Its digital input is referenced to V+, and analog signal range extends from V− to V+. This architecture allows operation in floating or split-rail systems without a dedicated ground reference - a key enabler for isolated sensor interfaces and portable battery-powered designs using the MAX4516ESA.
Can the MAX4516ESA be used with single-supply systems?
The MAX4516ESA can function with a single supply (e.g., V+ = +5V, V− = 0V), but its logic threshold remains referenced to V+, and analog range becomes 0V to +5V. For robust single-supply designs, Maxim recommends the pin-compatible MAX4514ESA, which is optimized for +2V to +12V operation and includes logic thresholds scaled for unipolar rails - unlike the MAX4516ESA.
What is the significance of the "NO" designation in MAX4516ESA?
"NO" stands for "normally open": the switch path between COM and NO is open (non-conductive) when the IN pin is LOW, and closes (conducts) only when IN is driven HIGH. This behavior is intrinsic to the MAX4516ESA die design and distinguishes it from the MAX4517ESA (NC version). System-level fault tolerance and power-up state are directly determined by this default-open configuration of the MAX4516ESA.
How does charge injection affect circuit performance when using the MAX4516ESA?
Charge injection in the MAX4516ESA - specified at 20pC maximum - causes a voltage glitch (∆V = Q/CL) on capacitive nodes when the switch turns OFF. In sample-and-hold or switched-capacitor circuits, this introduces settling error and offset. Designers mitigate this by minimizing load capacitance (CL) or adding reset pulses; the MAX4516ESA's guaranteed 20pC limit enables predictable compensation in precision ADC front-ends.
