Product details
Overview
MAX4516EPA 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, 1nA max off-leakage at +25°C, and rail-to-rail signal handling across ±1V to ±6V supplies - enabling precise signal routing in battery-powered audio and data-acquisition systems.
For engineers reviewing the MAX4516EPA datasheet, MAX4516EPA pinout, MAX4516EPA application, or MAX4516EPA equivalent, key selection criteria include guaranteed low on-resistance flatness (6Ω), fast switching (tON = 100ns), charge injection ≤20pC, and compatibility with ±5V CMOS logic levels referenced to V+.
Technical Context
The MAX4516EPA uses a dual-supply CMOS architecture with V+ and V− pins powering both analog switches and internal logic-level translators. Its NO configuration requires high logic input to close the COM–NO path, with no ground reference - logic thresholds scale with V+ (e.g., VIH ≈ V+ − 1.5V at V+ = +5V).
All analog terminals (COM, NO, IN) are protected by reverse ESD diodes to V+ and V−, making leakage current highly dependent on analog signal voltage relative to supply rails. Off-isolation reaches −86dB at 100kHz, and on-capacitance is 22pF, supporting bandwidth-critical routing in communications circuits and PCMCIA cards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 20Ω max at ±5V - ensures minimal signal attenuation and voltage drop in precision analog paths |
| On-Resistance Flatness | 6Ω max - maintains consistent gain/attenuation across full analog signal range (±4.5V) |
| Off-Leakage Current | 1nA max at +25°C - preserves signal integrity in high-impedance sensor interfaces |
| Charge Injection | 20pC max - limits voltage glitch on sampled nodes in data-acquisition 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-compatible input referenced to V+ - eliminates level-shifting in ±5V logic domains |
Pinout & Package
MAX4516EPA is housed in an 8-pin plastic DIP package (0.300" wide), suitable for through-hole prototyping and industrial control modules. Pin assignments are electrically identical to SO and SOT23-5 variants but mechanically distinct.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | COM | Common analog terminal - bidirectional signal path shared with NO or NC (MAX4516 uses NO only) |
| 2 | N.C. | No internal connection - must be left unconnected; not usable as spare I/O or thermal pad |
| 3 | NO | Normally-open analog terminal - forms closed path with COM only when IN = HIGH |
| 4 | V+ | Positive supply rail - powers analog switches and logic translator; sets upper analog voltage limit |
| 5 | N.C. | No internal connection - floating; no electrical function or thermal benefit |
| 6 | IN | Digital control input - CMOS-compatible, referenced to V+; drives internal gate drivers |
| 7 | V− | Negative supply rail - powers analog switches and logic translator; sets lower analog voltage limit |
| 8 | N.C. | No internal connection - electrically isolated; PCB layout must avoid unintended coupling |
Key Features
| Feature | Design Value |
|---|---|
| Low on-resistance flatness | 6Ω max over full signal range - minimizes THD and gain error in audio and instrumentation paths |
| Ultra-low off-leakage | 1nA at +25°C - critical for maintaining accuracy in high-Z sensor and medical front-end circuits |
| Controlled charge injection | ≤20pC - reduces settling error in sample-and-hold and ADC driver stages |
| Fast, asymmetric switching | tON > tOFF at ±5V - enables precise timing control in synchronous multiplexing applications |
| Dual-supply rail-to-rail operation | ±1V to ±6V - supports portable designs using single-cell Li-ion or dual alkaline supplies |
Applications
| Battery-Powered Audio Routing | Low-Voltage Data Acquisition |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4516ESA | Same silicon, 8-pin SO package; 100% tested at +25°C, temp-limits guaranteed by correlation | Suitable for automated SMT assembly; slightly higher parasitic capacitance (24pF vs. 22pF) | Select for volume production where reflow compatibility and board space are prioritized over through-hole serviceability |
| ADG1419BRMZ | Single-supply only (±15V max), 4.7Ω RON, but requires external level-shifter for ±5V logic interface | Higher performance in high-voltage test equipment; incompatible with direct ±5V CMOS control | Choose only when lower on-resistance justifies added BOM cost and layout complexity of level translation |
Compared with MAX4516ESA, the MAX4516EPA offers identical electrical specs with through-hole mounting for lab validation; versus ADG1419BRMZ, it trades lower RON for native dual-supply logic compatibility and simpler system integration.

FAQ
What is the operating temperature range of the MAX4516EPA?
The MAX4516EPA is rated for operation from −40°C to +85°C, making it suitable for industrial and extended-temperature environments. This grade exceeds the commercial 0°C to +70°C range of the 'C' suffix variants and is validated per Maxim's E-grade qualification standards, including thermal cycling and high-temperature operating life testing.
Does the MAX4516EPA require a ground connection?
No, the MAX4516EPA has no ground pin. Its digital input is referenced to V+, and analog signal range extends from V− to V+. This architecture eliminates ground-loop concerns in isolated systems but requires that all logic signals be referenced to the same V+ rail - connecting to a +5V TTL source while V+ = +3V violates absolute maximum ratings.
Can the MAX4516EPA be used with single-supply operation?
The MAX4516EPA is specified for dual-supply operation (±1V to ±6V) and is not characterized for single-supply use. While it may function with a single +2V to +12V supply, logic thresholds shift unpredictably, and leakage increases significantly. For single-supply designs, Maxim recommends the pin-compatible MAX4514 series instead.
What is the maximum analog signal frequency supported by the MAX4516EPA?
The MAX4516EPA maintains flat response up to 250MHz in 50Ω systems, with −3dB bandwidth exceeding 300MHz. However, off-isolation degrades above 20MHz (−48dB at 10MHz, decreasing ~20dB/decade), so high-frequency signal routing should prioritize on-state paths and minimize off-state coupling in RF-sensitive layouts.
How does the MAX4516EPA handle ESD events on analog pins?
The MAX4516EPA integrates reverse ESD-protection diodes from each analog pin (COM, NO) to both V+ and V−. These diodes clamp transients to within 0.3V of the supply rails, achieving >2000V HBM rating. To prevent damage, forward diode current must be limited to ±20mA continuous or ±30mA peak (1ms, 10% duty cycle).
