Product details
Overview
MAX4516CUK-T 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 up to ±6V supplies - enabling precision signal routing in battery-powered audio and data-acquisition systems.
For engineers reviewing the MAX4516CUK-T datasheet, MAX4516CUK-T pinout, MAX4516CUK-T application, or MAX4516CUK-T 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 MAX4516CUK-T implements a dual-supply CMOS transmission-gate 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 digital control referenced to V+ rather than ground.
Internal ESD diodes clamp analog signals exceeding V+ or V−, making leakage current highly dependent on signal voltage relative to supply rails. All analog leakage flows between signal pins and V+/V− - not between terminals - ensuring true bidirectional signal integrity without cross-path conduction.
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 accuracy in high-impedance sensor or sample-hold circuits |
| Charge Injection | 20pC max - limits voltage glitch on switched capacitive nodes (e.g., ADC inputs) |
| Switching Speed | tON = 100ns, tOFF = 75ns - supports >1MHz multiplexing without timing skew |
| Supply Range | ±1V to ±6V dual supply - enables operation from single Li-ion cell (±2.5V) to industrial ±5V rails |
| Logic Compatibility | CMOS-input referenced to V+ - eliminates need for level shifters when driving from same-supply microcontrollers |
Pinout & Package
SOT23-5 surface-mount package (3.0mm × 1.75mm × 1.3mm), lead-free and RoHS-compliant, optimized for automated placement and high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Digital control input | CMOS-compatible logic signal referenced to V+; high = closed path for MAX4516CUK-T |
| 2 - NO | Normally-open analog terminal | Connects to COM only when IN = high; bidirectional signal path with no polarity restriction |
| 3 - V− | Negative supply rail | Powers analog switch core and logic translator; sets lower analog voltage limit |
| 4 - V+ | Positive supply rail | Powers analog switch core and logic translator; sets upper analog voltage limit |
| 5 - COM | Analog common terminal | Shared node for signal routing; accepts rail-to-rail inputs up to ±6V with respect to V− |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports input voltages from V− to V+, enabling direct interface with op-amps and ADCs without clamping or level shifting |
| Guaranteed 20Ω RON at ±5V | Ensures predictable insertion loss and THD <0.01% in audio paths up to 100kHz |
| 1nA off-leakage at +25°C | Minimizes error in µA-range sensor interfaces and long-time-constant integrators |
| 20pC max charge injection | Reduces settling error in switched-capacitor circuits and sample-and-hold stages |
| 100ns turn-on time | Enables synchronous multiplexing of multi-channel sensor data at ≥1MHz update rates |
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 |
|---|---|---|---|
| MAX4514CUK-T | Single-supply operation (+2V to +12V); no V− pin; logic threshold referenced to VDD | Designed for systems with only positive supply; lacks true bipolar signal handling capability | Select when board uses only +3.3V or +5V rails and analog signals stay within 0V to VDD |
| ADG1211BRMZ-REEL7 | 12Ω RON at ±15V; higher supply range; 0.5pC typical charge injection; 10-lead MSOP | Targeted at high-precision industrial instrumentation requiring ultra-low glitch and wider voltage swing | Select when RON flatness <2Ω and sub-1pC charge injection are mandatory, accepting larger footprint and cost |
Compared with MAX4514CUK-T, the MAX4516CUK-T provides true dual-supply rail-to-rail analog operation essential for ±5V sensor conditioning, while ADG1211BRMZ-REEL7 offers superior precision at the expense of package size and supply flexibility - making MAX4516CUK-T optimal for compact, battery-powered systems needing balanced performance and integration.

FAQ
What is the maximum supply voltage range supported by the MAX4516CUK-T?
The MAX4516CUK-T operates continuously 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 operating range. For reliable long-term use, stay within ±5V unless validated per application requirements.
Is the MAX4516CUK-T pin-compatible with other variants in the MAX4516/MAX4517 family?
Yes - the MAX4516CUK-T shares identical SOT23-5 pinout with MAX4517CUK-T and all other SOT23-5 packaged variants (e.g., MAX4516EUK-T). Pin functions (IN, NO, V−, V+, COM) are fixed across the family; only logic behavior differs (NO vs NC). No PCB redesign is needed when substituting within the same package variant.
Does the MAX4516CUK-T require external pull-up or pull-down resistors on the IN pin?
No - the MAX4516CUK-T features CMOS-compatible digital inputs referenced to V+, with VIH = V+ − 1.5V and VIL = V+ − 3.5V (for V+ = +3V to +6V). Driving IN directly from a microcontroller GPIO powered by the same V+ rail eliminates need for external biasing; however, avoid interfacing with +5V TTL logic when V+ < +3.3V to prevent overvoltage damage.
How does temperature affect on-resistance in the MAX4516CUK-T?
On-resistance in the MAX4516CUK-T increases with temperature: RON is typically 15Ω at +25°C and rises to ~25Ω at +125°C under ±5V supplies. The datasheet guarantees ≤20Ω across 0°C to +70°C (commercial grade), with flatness maintained at ≤6Ω. For precision gain-critical paths, derating or calibration may be required above +85°C.
Can the MAX4516CUK-T handle AC signals exceeding its DC supply rails?
No - the MAX4516CUK-T cannot pass analog signals beyond V− or V+ due to internal ESD diode clamping. Signals must remain strictly within the rail-to-rail range (V− to V+). Exceeding either rail forward-biases protection diodes, causing current flow into V+ or V− and potential distortion or damage if current exceeds ±20mA continuous rating.
