Product details
Overview
The MAX361ESE+ from Maxim Integrated is a precision quad SPST analog switch with normally closed (NC) configuration, designed for high-fidelity signal routing in rail-to-rail analog paths. It delivers <85Ω max on-resistance, <2Ω channel-to-channel match, <9Ω on-resistance flatness, <4nA off-leakage at +85°C, and <10pC charge injection-enabling low-distortion sample-and-hold and test equipment signal switching.
For engineers reviewing the MAX361ESE+ datasheet, MAX361ESE+ pinout, MAX361ESE+ application, or MAX361ESE+ equivalent, this device is selected for precision analog multiplexing where leakage, charge injection, and resistance matching directly impact measurement accuracy and settling behavior in guidance systems, heads-up displays, and battery-operated instrumentation.
Technical Context
The MAX361ESE+ uses Maxim's 44V silicon-gate process to achieve rail-to-rail analog signal handling (±15.5V range with ±16.5V supplies) while maintaining CMOS/TTL logic compatibility. Its four independent NC switches are controlled by low-input-loading digital inputs, with guaranteed performance across -40°C to +85°C.
Operation supports both bipolar (±4.5V to ±20V) and single-supply (10V–30V) configurations. On-resistance matching and flatness are specified only under bipolar operation, and ESD robustness exceeds 2000V per Method 3015.7-critical for industrial and avionics environments requiring field-reliable analog switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (max) | 85Ω - Ensures minimal voltage drop and gain error in precision signal paths at full temperature range. |
| On-Resistance Match (max) | 2Ω - Enables accurate differential or ratiometric measurements across channels without calibration. |
| On-Resistance Flatness (max) | 9Ω - Maintains consistent gain and linearity over full analog input range (±15.5V). |
| Charge Injection (max) | 10pC - Limits voltage glitch on sampled capacitors, supporting sub-12-bit accuracy in S/H circuits. |
| Off-Leakage Current (max) | 4nA at +85°C - Prevents significant DC error accumulation in high-impedance sensor or integrator nodes. |
| Switching Speed (tON/tOFF) | 250ns / 170ns - Supports >1MHz multiplexed data acquisition without timing-induced aperture jitter. |
| Supply Range | ±4.5V to ±20V or +10V to +30V - Allows flexible power architecture in mixed-signal systems with legacy or isolated rails. |
Pinout & Package
MAX361ESE+ is housed in a 16-pin narrow SO package (5.0mm × 4.4mm body, 1.27mm pitch), RoHS-compliant and rated for -40°C to +85°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (Pins 15, 14, 7, 6) | Logic Control Input | CMOS/TTL-compatible digital inputs controlling NC state of respective switches; low input loading avoids bus contention. |
| COM1–COM4 (Pins 16, 13, 10, 2) | Analog-Switch Drain Terminal | Common analog node per switch; connects to load or signal source; must remain within (V− −2V) to (V+ +2V). |
| NC1–NC4 (Pins 1, 12, 11, 4) | Normally Closed Analog Terminal | Direct path to COM when IN = LOW; open-circuit when IN = HIGH; no internal connection to substrate. |
| V+ (Pin 11) | Positive Supply Voltage | Connected to substrate; sets upper analog rail and powers internal logic; max 44V breakdown. |
| V− (Pin 2) | Negative Supply Voltage | Sets lower analog rail; enables true bipolar signal handling; must be ≤ V+ − 44V. |
| GND (Pin 3) | Ground Reference | Digital ground reference for logic inputs; separate from analog return unless system design mandates common ground. |
| N.C. (Pin 10) | No Connection | Not internally connected; must be left floating or tied to GND for mechanical stability-no electrical function. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports ±15.5V signal swing with ±16.5V supplies-enables direct interface with op-amps and ADC drivers without level-shifting. |
| Guaranteed low charge injection | ≤10pC ensures <1mV glitch on 10nF hold capacitors-critical for 12-bit+ sample-and-hold fidelity. |
| Bipolar and single-supply operation | Operates from ±4.5V to ±20V or +10V to +30V-simplifies power design in mixed-voltage industrial and test systems. |
| ESD robustness | >2000V per Method 3015.7-reduces field failure risk in handling-sensitive applications like avionics and portable test gear. |
| Low power consumption | 35µW typical quiescent power-extends battery life in portable instrumentation and remote sensors. |
Applications
| Sample-and-Hold Circuits | Guidance and Control Systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX362ESE+ | Identical pinout, package, and specs-but normally open (NO) instead of NC; same leakage, RON, and charge injection. | Requires inverted logic control; unsuitable where fail-safe closed path is mandatory (e.g., safety interlocks). | Select MAX362ESE+ only when default-open behavior aligns with system fault strategy. |
| ADG444BRUZ | Quad NO switch in TSSOP-16; 75Ω max RON, 20pC charge injection, 10nA leakage at +85°C; operates up to +36V but not bipolar. | Lacks bipolar supply support and guaranteed RON matching; requires external level-shifting for ±15V signal paths. | Choose ADG444BRUZ only for unipolar, cost-sensitive designs where <10pC charge injection is noncritical. |
Compared with MAX361ESE+, MAX362ESE+ offers identical performance in NO configuration-ideal for logic-aligned switching-while ADG444BRUZ trades bipolar capability and ultra-low charge injection for broader voltage range and lower cost in unipolar systems.

FAQ
What is the maximum analog signal voltage range supported by the MAX361ESE+?
The MAX361ESE+ supports rail-to-rail analog signals from (V− −2V) to (V+ +2V), enabling ±15.5V operation with ±16.5V supplies. This range is guaranteed across the full -40°C to +85°C temperature range and is critical for interfacing with high-voltage op-amps and ADC drivers without attenuation or clipping. The 44V breakdown rating on V+ ensures margin against transients.
Does the MAX361ESE+ require power-supply sequencing, and what happens if it's not followed?
Yes-the MAX361ESE+ recommends sequencing V+ first, then V−, then logic inputs to avoid latch-up or overstress. If sequencing isn't feasible, two series diodes on V+ and V− pins provide overvoltage protection, reducing analog range by 1V but preserving all key specs (RON, leakage, charge injection). Unsequenced operation risks permanent damage per absolute maximum ratings.
How does the MAX361ESE+ perform in single-supply versus bipolar-supply configurations?
In bipolar mode (±4.5V to ±20V), the MAX361ESE+ guarantees <2Ω RON matching and <9Ω flatness; in single-supply mode (+10V to +30V), RON rises to 160Ω max and matching/flatness specs are not guaranteed. Bipolar operation is required for precision applications like sample-and-hold where channel consistency is essential.
Can the MAX361ESE+ be used in battery-powered systems, and what is its quiescent power draw?
Yes-the MAX361ESE+ draws only 35µW typical quiescent power (15µA at ±16.5V), making it suitable for long-life battery applications. Its ability to operate down to ±4.5V supplies allows direct use with dual-cell Li-ion or NiMH stacks. Low leakage (<4nA at +85°C) further minimizes standby current drain in always-on sensor nodes.
Is the N.C. pin (Pin 10) required to be grounded or left floating on the MAX361ESE+?
Pin 10 (N.C.) is not internally connected and may be left floating. However, grounding it improves mechanical stability and reduces potential for parasitic coupling in high-density layouts. Neither choice affects electrical performance-no current flows, and no specification depends on its state. Always verify layout clearance per JEDEC MO-178 standards.
