Product details
Overview
MAX301ESE from Maxim Integrated is a precision dual SPST analog switch optimized for high-accuracy signal routing in bipolar or single-supply systems. It features 35Ω max on-resistance, <2Ω channel-to-channel matching, <15pC charge injection, rail-to-rail analog signal handling (V− to V+), and operates across −40°C to +85°C. It is used in test equipment, military radios, and precision sample-and-hold circuits where low distortion and tight matching are critical.
For engineers reviewing the MAX301ESE datasheet, MAX301ESE pinout, MAX301ESE application, or MAX301ESE equivalent, key selection criteria include guaranteed on-resistance flatness (Δ3Ω max), sub-100ns turn-off time, ±4.5V to ±20V dual-supply compatibility, and 16-pin narrow SO package thermal performance for industrial embedded designs.
Technical Context
The MAX301ESE implements two independent normally-open (NO) analog switches fabricated using Maxim's silicon-gate process, ensuring low charge injection (15pC typ) and matched on-resistance (<2Ω between channels). Its CMOS/TTL-compatible logic inputs (VL = +5V) interface directly with microcontrollers without level-shifting.
It supports rail-to-rail analog signals from V− to V+, with breakdown voltage up to 44V, enabling operation with ±15V supplies or +24V single supply. Dynamic performance includes 150ns max turn-on and 100ns max turn-off times into 1000Ω/35pF loads, verified at TA = +25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (max) | 35Ω - Ensures minimal signal attenuation and gain error in precision gain-setting or multiplexing paths. |
| On-Resistance Match (max) | 2Ω - Guarantees ≤0.1% gain mismatch between dual channels in differential or ratiometric applications. |
| Charge Injection (max) | 15pC - Limits voltage glitch on sampled capacitors, critical for <12-bit accuracy in sample-and-hold stages. |
| Off-Leakage Current (max) | 6nA at +85°C - Prevents measurable DC error buildup in high-impedance sensor interfaces or integrators. |
| Turn-Off Time (max) | 100ns - Enables >5MHz switching rates in automated test equipment and fast data acquisition systems. |
| Analog Signal Range | V− to V+ - Supports true rail-to-rail signal switching without clamping or headroom loss. |
| Supply Voltage Range | ±4.5V to ±20V or +10V to +30V - Allows flexible integration into legacy ±15V systems or modern +24V industrial rails. |
Pinout & Package
MAX301ESE is housed in a 16-pin narrow SOIC (S16-2) package, 7.5mm × 10.3mm, with standard JEDEC MS-012AC footprint and 1.27mm pitch. Thermal resistance θJA = 115°C/W enables operation up to +85°C ambient without forced airflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | COM1, COM2 | Common analog terminals - bidirectional signal path; must be routed with controlled impedance for high-frequency integrity. |
| 9, 16 | NO1, NO2 | Normally-open switch outputs - connect to load or downstream circuit only when INx = HIGH. |
| 10, 15 | IN2, IN1 | CMOS/TTL logic inputs - accept 0V/+5V control; no external pull-ups required due to internal biasing. |
| 11 | V+ | Positive supply input - connects to substrate; must be decoupled locally with 0.1µF ceramic capacitor. |
| 12 | VL | Logic supply input - fixed at +5V for TTL compatibility; ties to V+ only if CMOS-level logic is used. |
| 13 | GND | Ground reference - serves as negative supply return; requires low-inductance connection to system ground plane. |
| 14 | V− | Negative supply input - establishes lower analog rail; must be decoupled identically to V+. |
| 2–7 | N.C. | No internal connection - left unconnected; no thermal or EMI impact when floating. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog switching | Supports full V− to V+ signal range without clipping - essential for ±10V instrumentation front-ends. |
| Guaranteed on-resistance flatness | Δ3Ω max over full signal range - eliminates gain nonlinearity in programmable gain amplifiers. |
| Low temperature coefficient | 0.5%/°C typical on-resistance drift - maintains matching stability across −40°C to +85°C operating range. |
| Bipolar and single-supply operation | Operates natively with ±4.5V to ±20V or +10V to +30V - simplifies power architecture in mixed-signal systems. |
| Ultra-low leakage at temperature | <6nA off-leakage at +85°C - preserves accuracy in high-Z medical sensor or battery-monitoring circuits. |
Applications
| Test Equipment Signal Routing | Military Radio Channel Switching |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1419BRUZ | Higher on-resistance (1.3Ω typ), wider supply range (±5V to ±22V), but higher charge injection (18pC max). | Better suited for high-voltage industrial PLC I/O modules requiring >±20V tolerance. | Select ADG1419BRUZ only if ±22V operation is mandatory; MAX301ESE offers superior matching and lower charge injection for metrology-grade designs. |
| TS5A23157DCKR | Lower voltage rating (+5.5V max), smaller 6-pin SC70 package, but significantly higher on-resistance (0.9Ω typ) and no guaranteed matching. | Targeted at space-constrained consumer electronics, not precision industrial or military use. | TS5A23157DCKR is unsuitable for MAX301ESE replacement in any application requiring rail-to-rail ±15V operation or sub-2Ω matching. |
Compared with ADG1419BRUZ and TS5A23157DCKR, the MAX301ESE uniquely delivers guaranteed 2Ω channel matching and 15pC charge injection within a rugged −40°C to +85°C industrial SOIC package - making it irreplaceable for high-fidelity signal routing where parameter correlation matters more than raw voltage range or footprint size.

FAQ
What is the maximum allowable supply voltage for MAX301ESE?
The MAX301ESE has an absolute maximum V+ to V− rating of 44V. Operation is specified across ±4.5V to ±20V bipolar supplies or +10V to +30V single supply. Exceeding ±20V or +30V risks permanent damage per Absolute Maximum Ratings. The MAX301ESE must never see V+ − V− > 44V, even transiently.
Does MAX301ESE support rail-to-rail analog signal switching?
Yes, the MAX301ESE supports true rail-to-rail analog signal switching from V− to V+. Its internal architecture allows analog signals equal to the supply rails (e.g., −15V to +15V) to pass with minimal distortion, confirmed by guaranteed on-resistance flatness (Δ3Ω max) across the full range.
What is the guaranteed on-resistance matching between channels for MAX301ESE?
The MAX301ESE guarantees on-resistance matching of ≤2Ω between its two SPST switches across the full operating temperature range (−40°C to +85°C), as specified in the Electrical Characteristics table under "On-Resistance Match Between Channels." This is measured at V+ = 15V, V− = −15V, and TA = TMIN to TMAX.
Can MAX301ESE operate with TTL-level logic inputs?
Yes, the MAX301ESE accepts TTL-level logic inputs when VL is tied to +5V. Its logic inputs meet TTL thresholds (VINH ≥ +2.4V, VINL ≤ +0.8V) and draw <1µA input current. If VL is connected to V+, CMOS-level compatibility applies instead - the MAX301ESE does not auto-detect logic family.
Is charge injection specified for MAX301ESE, and what is its impact?
Yes, the MAX301ESE guarantees charge injection ≤15pC, measured per Figure 3 in the datasheet. This low value minimizes voltage glitches on hold capacitors in sample-and-hold circuits - for example, with a 10nF capacitor, 15pC injection causes only 1.5mV step error, preserving accuracy in 12-bit+ systems.
