Product details
Overview
MAX4516EUK-T from Maxim Integrated is a single-pole/single-throw (SPST), normally open (NO), CMOS analog switch optimized for low-voltage dual-supply operation (±1V to ±6V), featuring 20Ω on-resistance at ±5V, 1nA off-leakage at +25°C, and rail-to-rail signal handling - used in battery-powered audio routing and low-voltage data-acquisition front-ends.
For engineers reviewing the MAX4516EUK-T datasheet, MAX4516EUK-T pinout, MAX4516EUK-T application, or MAX4516EUK-T equivalent, key selection criteria include guaranteed on-resistance flatness (6Ω), charge injection (20pC max), fast switching (tON = 100ns), and SOT23-5 package compatibility with space-constrained portable designs.
Technical Context
The MAX4516EUK-T implements a dual-supply CMOS transmission gate architecture with V+ and V− pins powering both analog switch elements and internal logic-level translators. Its control input is referenced to V+, enabling CMOS-compatible logic thresholds across ±5V supplies without ground reference.
Internal ESD diodes clamp analog terminals to V+ and V−, making leakage current highly dependent on signal voltage relative to supply rails. The device supports bidirectional signal flow with identical NO/NC/COM terminal behavior, and exhibits tON > tOFF timing asymmetry at ±5V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | ±1V to ±6V dual supply - enables operation in ultra-low-voltage systems down to ±1V while maintaining rail-to-rail analog signal swing. |
| On-Resistance (RON) | 20Ω max at ±5V - ensures minimal signal attenuation and distortion in precision analog paths. |
| Off-Leakage Current | 1nA max at +25°C - preserves signal integrity in high-impedance sensor interfaces and sample-hold circuits. |
| Charge Injection | 20pC max - limits voltage glitch on switched capacitive nodes, critical for ADC front-end multiplexing. |
| Switching Speed | tON = 100ns, tOFF = 75ns - supports moderate-speed signal routing in communications and modem applications. |
| On-Resistance Flatness | 6Ω max - maintains consistent gain and linearity across full analog input range (±4.5V). |
| Off Isolation | −86dB at 100kHz - suppresses crosstalk between active and inactive channels in multi-signal routing. |
Pinout & Package
SOT23-5 surface-mount package (3.0mm × 1.75mm × 1.3mm), rated for −40°C to +85°C operation, with exposed pad not internally connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Digital control input | CMOS-compatible logic input referenced to V+; HIGH turns switch ON (MAX4516EUK-T is NO type). |
| 2 - NO | Analog switch terminal | Normally open path; connects to COM when IN = HIGH - serves as signal input or output depending on system topology. |
| 3 - V− | Negative supply rail | Powers analog switch core and logic translator; sets lower analog voltage limit and clamps ESD diodes. |
| 4 - COM | Common analog terminal | Bidirectional signal node shared by NO (and NC in MAX4517); must be routed with controlled impedance in RF-sensitive layouts. |
| 5 - V+ | Positive supply rail | Powers analog switch core and logic translator; sets upper analog voltage limit and clamps ESD diodes. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports input signals from V− to V+ without clipping - essential for full-scale dynamic range in portable audio codecs. |
| Guaranteed 20Ω RON at ±5V | Ensures predictable insertion loss and channel matching in multi-channel data acquisition systems. |
| 1nA off-leakage at +25°C | Minimizes error in high-impedance sensor front-ends (e.g., thermocouples, pH electrodes) over extended sampling intervals. |
| 20pC max charge injection | Reduces settling error in capacitor-based sample-and-hold or switched-capacitor filter stages. |
| Fast 100ns turn-on time | Enables time-division multiplexing of multiple analog sources at up to ~5MHz effective update rate. |
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 |
|---|---|---|---|
| MAX4514EUK-T | Single-supply only (+2V to +12V); no V− pin; logic threshold referenced to VDD. | Designed for systems lacking negative rail; unsuitable where true bipolar signal handling required. | Select when board uses only positive supply and analog signals stay within 0V to VDD. |
| ADG1219BRMZ-REEL | Higher RON (120Ω typ), wider temp range (−40°C to +125°C), 5V single-supply only. | Lacks dual-supply capability and rail-to-rail analog swing; better suited for industrial control over consumer portables. | Choose for extended temperature reliability where ±5V operation is unnecessary and layout allows larger SOIC-8 footprint. |
Compared with MAX4516EUK-T, MAX4514EUK-T simplifies power design but sacrifices bipolar signal support, while ADG1219BRMZ-REEL trades on-resistance and supply flexibility for broader temperature tolerance and higher voltage robustness - neither is pin-compatible, requiring PCB redesign.

FAQ
What is the operating temperature range for MAX4516EUK-T?
The MAX4516EUK-T is specified for operation from −40°C to +85°C. This extended industrial temperature grade is confirmed in the Ordering Information table and Absolute Maximum Ratings section of the datasheet, distinguishing it from the commercial-grade MAX4516CUK (0°C to +70°C). The SOT23-5 package's thermal characteristics support reliable performance across this full range without derating.
Does MAX4516EUK-T support single-supply operation?
No, MAX4516EUK-T requires dual supplies (V+ and V−) and is not rated for single-supply use. While the device may function with a single positive supply under certain conditions, its electrical specifications - including on-resistance, leakage, and logic thresholds - are only guaranteed under dual-supply operation from ±1V to ±6V. For single-supply applications, Maxim recommends the pin-compatible MAX4514EUK-T instead.
What is the maximum analog signal voltage range supported by MAX4516EUK-T?
The MAX4516EUK-T supports rail-to-rail analog signals from V− to V+, meaning the full analog input range equals the difference between the two supply rails. With ±5V supplies, the usable analog range is −5V to +5V. This is explicitly stated in the "Analog Signal Range" parameter (VCOM, VNO, VNC: V− to V+) and verified in Figure 1 (ON-Resistance vs. VCOM), which plots performance across ±4.5V.
Is MAX4516EUK-T pin-compatible with MAX4517EUK-T?
Yes, MAX4516EUK-T and MAX4517EUK-T share identical SOT23-5 pinouts and package dimensions, differing only in functional state: MAX4516EUK-T is normally open (NO), while MAX4517EUK-T is normally closed (NC). Both use the same IN, NO/NC, COM, V+, and V− pin assignments, allowing direct substitution in layouts where the required default state matches the application's fail-safe requirement.
What does the "E" in MAX4516EUK-T signify?
The "E" in MAX4516EUK-T denotes the extended temperature grade (−40°C to +85°C), as defined in the Ordering Information table. The "U" indicates SOT23-5 package, "K" specifies tape-and-reel packaging, and "-T" confirms tape-and-reel delivery format. This full suffix distinguishes it from commercial-grade variants like MAX4516CUK and military-grade MAX4516MJA.
