Product details
Overview
MAX312ESE+ from Maxim Integrated is a quad, normally closed (NC), single-pole/single-throw (SPST) CMOS analog switch optimized for precision signal routing in bipolar and single-supply systems. It delivers 6.5Ω typical on-resistance, 1.5Ω max on-resistance matching between channels, rail-to-rail signal handling up to ±15V, and 2.5nA max off-leakage at +85°C - enabling high-fidelity audio switching and low-error data acquisition.
For engineers reviewing the MAX312ESE+ datasheet, MAX312ESE+ pinout, MAX312ESE+ application, or MAX312ESE+ equivalent, key selection criteria include guaranteed RON flatness (≤2Ω), >96dB crosstalk at 20kHz, ESD tolerance >2000V per Method 3015.7, and compatibility with DG411/DG412/DG413 footprints in 16-pin narrow SO packages.
Technical Context
The MAX312ESE+ implements a fully complementary CMOS transmission-gate architecture with matched P- and N-channel devices per channel, ensuring symmetrical conduction and minimal charge injection (±30pC). Its logic interface accepts TTL/CMOS-compatible inputs referenced to VL (2.4V/0.8V thresholds) and operates independently of analog supply polarity.
It supports dual-supply operation from ±4.5V to ±20V or single-supply operation from +4.5V to +30V, with rail-to-rail analog signal range extending from V− to V+. The device guarantees break-before-make timing only in the MAX314 variant; MAX312ESE+ is strictly NC and does not implement internal sequencing logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 6.5Ω typical, ≤10Ω max - ensures minimal signal attenuation and voltage drop in precision analog paths. |
| RON Matching | ≤1.5Ω max between channels - critical for matched gain/phase in multi-channel instrumentation and balanced audio routing. |
| Off-Leakage Current | ±2.5nA max at +85°C - preserves accuracy in high-impedance sample-and-hold and sensor front-ends. |
| Crosstalk | >96dB at 20kHz - prevents audible interference in stereo audio signal switching applications. |
| Supply Range | +4.5V to +30V (single) or ±4.5V to ±20V (dual) - enables direct integration into industrial control and avionics power domains. |
| ESD Protection | >2000V per Method 3015.7 - meets basic system-level ESD robustness requirements without external protection. |
| Charge Injection | ±30pC max - limits voltage glitch on high-impedance nodes during switching, e.g., in ADC input multiplexing. |
Pinout & Package
MAX312ESE+ is housed in a 16-pin narrow SOIC (SO) package (JEDEC MS-012, 3.9mm width), with lead finish Sn/Pb and RoHS-compliant variants available under different suffixes. Pin 1 is located at the top-left corner adjacent to the index mark.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Logic control inputs; active-high for channel enable (logic '1' closes NC path). |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - bidirectional signal ports connected to NC switches when enabled. |
| 3, 6, 11, 14 | NC1–NC4 | Normally closed analog terminals - shorted to respective COM pins when IN = 0V; open when IN ≥2.4V. |
| 4 | V+ | Positive analog supply - must be ≥+4.5V (single) or ≤+44V absolute max; defines upper analog rail. |
| 5 | GND | Logic ground reference - tied to system digital ground; separate from analog return unless single-supply design. |
| 12 | VL | Logic supply voltage - accepts 2.0V to V+; sets input threshold (2.4V/0.8V) and drives internal level shifters. |
| 13 | V− | Negative analog supply - required for dual-supply operation; connects to GND for single-supply use. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ - eliminates clipping in ±15V op-amp circuits and audio line drivers. |
| Guaranteed RON flatness | ≤2Ω variation over full signal range - maintains consistent gain and THD across amplitude in audio paths. |
| Pin compatibility with DG411/DG412/DG413 | Direct PCB footprint replacement for legacy Vishay/Intersil switches - reduces redesign effort in upgrade projects. |
| Low temperature drift | On-resistance increases only ~15% from −40°C to +85°C - ensures stable performance in automotive and industrial environments. |
| High off-isolation | ≥65dB at 1MHz - suppresses coupling between unused channels in test equipment multiplexers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX312CSE+ | Same electrical specs, but rated for 0°C to +70°C commercial temperature range only. | Not suitable for extended-temperature industrial or automotive deployments requiring −40°C startup. | Select MAX312CSE+ only for cost-sensitive, ambient-temperature lab equipment where thermal margin is assured. |
| ADG411BRZ | Pin-compatible quad SPST switch (NC), but higher RON (35Ω typ), lower ESD rating (1500V), and no guaranteed RON match spec. | Limited to lower-bandwidth (<1MHz), non-critical signal routing where leakage and matching are less constrained. | Choose ADG411BRZ only if existing BOM uses Analog Devices ecosystem and thermal/precision margins allow higher RON and leakage. |
Compared with MAX312CSE+, MAX312ESE+ adds −40°C to +85°C operation and tighter production screening; compared with ADG411BRZ, it delivers 5.4× lower RON, 33% better leakage control, and guaranteed matching - making it superior for precision, wide-temperature, or high-fidelity analog routing.

FAQ
What is the maximum allowable analog signal range for MAX312ESE+?
The MAX312ESE+ supports rail-to-rail analog signals from V− to V+. With dual supplies of ±15V, the signal range is −15V to +15V; with a single +12V supply (V− = GND), it is 0V to +12V. Absolute maximum ratings limit V+ to +44V and V− to −44V, but operation beyond ±20V requires derating per the datasheet's power dissipation curves. Exceeding these ranges risks permanent damage.
Is MAX312ESE+ pin-compatible with the DG411 analog switch?
Yes, MAX312ESE+ is explicitly designed as a pin-compatible replacement for the DG411. Both are quad, normally closed SPST switches in 16-pin SOIC packages with identical pin assignments for IN, COM, NC, V+, V−, GND, and VL. No PCB layout changes are required when upgrading from DG411 to MAX312ESE+, though designers should verify logic voltage levels and supply decoupling per Maxim's recommendations.
Does MAX312ESE+ support break-before-make switching?
No, MAX312ESE+ does not implement break-before-make functionality. It is a simple normally closed (NC) SPST switch: each channel transitions directly between closed and open states without an intermediate isolation gap. Break-before-make timing is only specified for the MAX314 variant (which combines NC and NO switches); using MAX312ESE+ in applications requiring guaranteed channel isolation during switching requires external timing control or additional circuitry.
What is the typical on-resistance flatness specification for MAX312ESE+?
The MAX312ESE+ guarantees on-resistance flatness of ≤2Ω maximum over its full specified analog signal range (e.g., ±10V with ±15V supplies). This means the difference between the highest and lowest RON values measured across the entire input voltage swing remains within 2Ω - a critical parameter for minimizing harmonic distortion in audio applications and ensuring linear gain in programmable gain amplifier stages.
Can MAX312ESE+ operate from a single 5V supply?
No, MAX312ESE+ cannot operate reliably from a single 5V supply. Its minimum single-supply voltage is +4.5V, but the datasheet specifies performance only down to +4.5V with significant RON degradation and reduced leakage control below +9V. At +5V, RON rises to ~25Ω (typ), and off-leakage increases substantially. For 5V-system compatibility, consider the MAX4617 or MAX4624 families, which are optimized for low-voltage operation.
