Product details
Overview
MAX4516CPA+ 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, 1nA 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 MAX4516CPA+ datasheet, MAX4516CPA+ pinout, MAX4516CPA+ application, or MAX4516CPA+ equivalent, key selection criteria include guaranteed low RON flatness (6Ω), fast switching (tON = 100ns), charge injection ≤20pC, and SOT23-5 package compatibility with space-constrained portable designs.
Technical Context
The MAX4516CPA+ uses a dual-supply CMOS architecture with V+ and V− pins powering both analog switches and internal logic-level translators. Its NO configuration ensures open-circuit default state, eliminating unintended signal paths during power-up or control loss.
Internal ESD diodes clamp analog pins to V+ and V−, making leakage current highly dependent on signal voltage relative to supply rails. Logic inputs are referenced to V+, requiring CMOS-compatible thresholds (e.g., VIH ≈ V+ − 1.5V at +5V supply) - not TTL-compatible.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 20Ω max at ±5V - ensures minimal signal attenuation and distortion in precision analog paths |
| On-Resistance Flatness | 6Ω max - maintains consistent gain/attenuation across full analog input range (±4.5V) |
| Off-Leakage Current | 1nA max at +25°C - preserves signal integrity in high-impedance sensor or sample-hold circuits |
| Charge Injection | 20pC max - limits voltage glitch on switched nodes, critical for ADC front-end multiplexing |
| Switching Speed | tON = 100ns, tOFF = 75ns - supports >1MHz multiplexing without timing skew in data acquisition |
| Analog Signal Range | Rail-to-rail (V− to V+) - enables full utilization of supply headroom in ±5V systems |
| Supply Voltage Range | ±1V to ±6V dual supply - allows operation from single-cell Li-ion (±2.5V) up to industrial ±5V rails |
Pinout & Package
MAX4516CPA+ is housed in an industry-standard 5-pin SOT23-5 package (JEDEC MO-178AA), with exposed pad omitted and thermal resistance θJA = 220°C/W. Pin 1 = IN (digital control), Pin 2 = NO (normally open switch terminal), Pin 3 = V−, Pin 4 = V+, Pin 5 = COM (common analog terminal).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Digital control input | CMOS-compatible logic input referenced to V+; HIGH = switch closed (NO→COM), LOW = open |
| NO | Normally open analog terminal | Connects to COM only when IN = HIGH; bidirectional signal path with matched RON |
| V− | Negative analog/digital supply | Sets lower analog voltage limit and powers internal CMOS gates; must be stable and low-noise |
| V+ | Positive analog/digital supply | Sets upper analog voltage limit and powers logic translator; defines VIH/VIL thresholds |
| COM | Common analog terminal | Shared node for signal routing; accepts rail-to-rail inputs and drives loads up to ±30mA peak |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed low RON | 20Ω max at ±5V ensures <0.1% gain error in 10kΩ impedance interfaces |
| Ultra-low off-leakage | 1nA at +25°C prevents DC offset drift in µA-range sensor front-ends |
| Low charge injection | 20pC max minimizes settling time in sample-and-hold or multiplexer-driven ADC inputs |
| Fast, asymmetric switching | tON > tOFF at ±5V enables predictable timing margins in synchronous routing applications |
| True dual-supply operation | ±1V to ±6V range supports direct interface with op-amps, DACs, and sensors without level-shifting |
Applications
| Portable Audio Routing | Battery-Powered Data Acquisition |
|---|---|
Use Scenario: Selecting between microphone and line-in signals in Bluetooth headsets or voice recorders. IC Role / Device Role / Timing Role: SPST analog switch isolating input paths while preserving THD <0.01% at 1kHz. Use Value: 20Ω RON and 20pC charge injection prevent audible clicks and maintain SNR >95dB. |

IC Role / Device Role / Timing Role: Fast 100ns turn-on ensures reliable capture of 20ms ring-trip pulses without signal truncation. Use Value: tON/tOFF asymmetry provides deterministic timing margin against pulse-width jitter in telephony standards. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4514CPA+ | Single-supply only (+2V to +12V); no V− pin; logic threshold referenced to GND | Designed for +3.3V or +5V-only systems; lacks true bipolar signal handling | Select when system uses single-rail supply and does not require negative analog signals |
| ADG1219BRMZ | Higher RON (125Ω typ), wider temp range (−40°C to +125°C), SPI-controlled | Targeted at industrial PLC I/O modules needing extended temperature and digital configurability | Select when programmable enable/disable via serial interface outweighs need for ultra-low RON |
Compared with MAX4514CPA+, the MAX4516CPA+ supports true bipolar analog signals and lower RON, but requires dual supplies; compared with ADG1219BRMZ, it offers faster switching and lower leakage, but lacks digital control and extended temperature rating.

FAQ
What is the maximum supply voltage range supported by the MAX4516CPA+?
The MAX4516CPA+ operates with dual supplies from ±1V to ±6V. Absolute maximum ratings allow V+ up to +13V and V− down to −0.3V, but guaranteed performance (including RON, leakage, and timing) applies only within the ±1V to ±6V range. Operation outside ±5V requires validation per application conditions.
Is the MAX4516CPA+ pin-compatible with the MAX4517CPA+?
Yes, the MAX4516CPA+ and MAX4517CPA+ share identical pinouts and packages (SOT23-5, DIP, SO), differing only in default switch state: MAX4516CPA+ is normally open (NO), while MAX4517CPA+ is normally closed (NC). No PCB changes are required when swapping between them for functional inversion.
Does the MAX4516CPA+ support rail-to-rail analog signal switching?
Yes, the MAX4516CPA+ supports rail-to-rail analog signal switching - meaning signals from V− to V+ can pass through the switch with full fidelity. This is enabled by its dual-supply architecture and CMOS transmission-gate design, confirmed in the Electrical Characteristics table under "Analog Signal Range".
What is the typical charge injection value for the MAX4516CPA+ and why does it matter?
The MAX4516CPA+ has a maximum charge injection of 20pC. This parameter quantifies the transient voltage glitch induced on the COM node when the switch turns off. In sample-and-hold or multiplexer-driven ADC applications, low charge injection (<25pC) directly reduces settling time and prevents code errors - critical for 16-bit+ resolution systems.
Can the MAX4516CPA+ be used with a single supply voltage?
The MAX4516CPA+ is designed for dual-supply operation and is not characterized for single-supply use. While it may function with a single +2V to +12V supply, logic thresholds shift unpredictably and analog performance (e.g., RON, leakage) is not guaranteed. For single-supply applications, Maxim recommends the pin-compatible MAX4514CPA+ instead.
