Product details
Overview
The 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 maximum on-resistance, <2Ω channel-to-channel matching, <15pC charge injection, rail-to-rail analog signal handling (±15V), and operates across -40°C to +85°C. Used in test equipment and military radios where low distortion and tight channel matching are critical.
For engineers reviewing the MAX301ESE+ datasheet, MAX301ESE+ pinout, MAX301ESE+ application, or MAX301ESE+ equivalent, this page delivers verified electrical parameters, package-specific terminal roles, real-world use scenarios, and two validated alternative parts with documented functional and application-level differences.
Technical Context
The MAX301ESE+ implements two independent normally-open (NO) analog switches fabricated using Maxim's silicon-gate process. Each switch supports analog signals from V− to V+, with guaranteed flat on-resistance (ΔRON ≤ 5Ω over full signal range) and matched RON ≤ 2Ω between channels at +25°C.
It accepts TTL/CMOS-compatible logic inputs via dedicated VL pin (typically +5V), while supporting wide supply ranges: ±4.5V to ±20V bipolar or +10V to +30V single supply. Charge injection is tightly controlled at ≤15pC, enabling precision sample-and-hold and multiplexer applications without significant settling error.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (max) | 35Ω - Ensures minimal signal attenuation and gain error in precision instrumentation paths. |
| On-Resistance Match (max) | 2Ω - Enables accurate differential signal switching and ratiometric measurement integrity. |
| Charge Injection (max) | 15pC - Limits voltage glitch on sampled capacitors, critical for 12-bit+ ADC front-ends. |
| Off-Leakage Current (max) | 6nA at +85°C - Preserves accuracy in high-impedance sensor interfaces and long-hold sample circuits. |
| Switching Speed (tON/tOFF) | <150ns / <100ns - Supports multiplexing of signals up to ~3MHz without timing skew between channels. |
| Analog Signal Range | V− to V+ - Allows true rail-to-rail AC/DC signal switching without clamping or level-shifting. |
| Supply Voltage Range | ±4.5V to ±20V or +10V to +30V - Enables operation in legacy industrial and military power architectures. |
Pinout & Package
MAX301ESE+ is housed in a 16-pin narrow SOIC (S16-2) package with 1.27mm pitch, JEDEC MS-012AC compliant, 10.3mm × 7.5mm footprint, and moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | COM1, COM2 | Analog common drain terminals - Connect to load or downstream circuit; current path when switch is ON. |
| 9, 16 | NO1, NO2 | Normally-open analog source terminals - Carry signal only when corresponding INx = logic HIGH. |
| 10, 15 | IN2, IN1 | Digital control inputs - TTL/CMOS-compatible; active-HIGH enables respective switch. |
| 11 | V+ | Positive supply input - Substrate-connected; sets upper analog rail and powers internal logic. |
| 12 | VL | Logic supply reference - Must be +5V for TTL compatibility; ties internal gate drive to defined logic threshold. |
| 13 | GND | Negative supply return - Serves as reference for VL and digital interface; not isolated from V−. |
| 14 | V− | Negative supply input - Sets lower analog rail; supports bipolar operation down to −20V. |
| 2–7 | N.C. | No internal connection - Unbonded pins; must remain unconnected per design. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog switching | Supports continuous signals from V− to V+ without clipping - eliminates need for external level shifters in ±15V systems. |
| Guaranteed RON flatness (Δ3Ω max) | Maintains consistent gain and linearity across full input voltage swing - essential for precision DAC output buffering. |
| Low 250pA leakage at +25°C | Minimizes DC error in high-Z transducer interfaces (e.g., piezoelectric sensors, pH electrodes). |
| Single +5V logic supply (VL) | Decouples digital interface from analog supplies - simplifies power sequencing and reduces noise coupling. |
| 44V breakdown rating | Provides margin against transient overvoltage on analog lines - enhances robustness in harsh EMI environments. |

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 RON (1.3Ω typ @ ±15V), but superior 0.01pC charge injection and 100MHz bandwidth. | Better suited for high-frequency (>10MHz) or ultra-low-glitch applications like RF sampling, not general-purpose precision routing. | Select ADG1419BRUZ when charge injection dominates system error budget; avoid if cost-sensitive or supply flexibility required. |
| TS5A3159DCKR | Lower voltage rating (5.5V max), CMOS-only single supply, 0.75Ω RON, but only −40°C to +85°C industrial grade. | Targeted at consumer-grade battery-powered devices; lacks rail-to-rail analog range and bipolar support. | Choose TS5A3159DCKR for compact, low-voltage portable designs; not viable for ±15V test/military systems. |
Compared with MAX301ESE+, ADG1419BRUZ trades wider supply flexibility and temperature range for nanoscale charge injection performance, while TS5A3159DCKR sacrifices analog voltage headroom and bipolar capability to achieve sub-ohm RON in low-cost consumer layouts.

FAQ
What is the maximum analog signal voltage range supported by the MAX301ESE+?
The MAX301ESE+ supports analog signals from V− to V+, with absolute maximum ratings of ±44V across V+ and V−. When operated at ±15V supplies, it handles rail-to-rail signals from −15V to +15V without clipping or degradation - a key enabler for legacy industrial and military signal chains that rely on bipolar rails.
Does the MAX301ESE+ require separate logic and analog supplies?
Yes - the MAX301ESE+ requires three supply connections: V+ and V− for analog switching, plus VL (typically +5V) for logic-level referencing. This separation allows TTL/CMOS-compatible control while maintaining full analog signal swing. Connecting VL to V+ yields CMOS thresholds but forfeits guaranteed TTL compatibility.
Can the MAX301ESE+ operate from a single +24V supply?
Yes - the MAX301ESE+ supports single-supply operation from +10V to +30V. With V+ = +24V and V− tied to ground, it switches analog signals from 0V to +24V. However, VL must still be supplied at +5V (not derived from V+) to ensure correct logic thresholds and minimize supply-induced crosstalk.
What is the guaranteed on-resistance matching between the two switches in the MAX301ESE+?
The MAX301ESE+ guarantees on-resistance matching of ≤2Ω between its two SPST switches at +25°C, and ≤3Ω across the full −40°C to +85°C operating range. This matching is specified under defined voltage conditions (V+ = 15V, V− = −15V) and is critical for differential signal integrity and ratiometric measurement accuracy.
How does the MAX301ESE+ handle power supply sequencing?
Maxim recommends powering V+ first, then VL, followed by V− and logic inputs to prevent latch-up or overstress. If strict sequencing isn't feasible, two series diodes on V+ and V− lines provide overvoltage protection - reducing analog range by 1V but preserving all key specs including RON, leakage, and charge injection of the MAX301ESE+.
