Product details
Overview
MAX312LCSE+TG52 from Maxim Integrated is a quad, normally closed (NC), single-pole/single-throw (SPST) analog switch IC designed for precision signal routing in ±4.5V to ±20V or +4.5V to +36V systems. It delivers 10Ω max on-resistance, 1.5Ω max on-resistance matching between channels, and rail-to-rail analog signal handling up to ±15V, enabling low-distortion audio routing and high-fidelity data-acquisition front-ends.
For engineers reviewing the MAX312LCSE+TG52 datasheet, MAX312LCSE+TG52 pinout, MAX312LCSE+TG52 application, or MAX312LCSE+TG52 equivalent, this page provides verified electrical specs, SO-16 pin mapping, real-world use cases in avionics and xDSL modems, and validated alternative parts with documented functional trade-offs.
Technical Context
The MAX312LCSE+TG52 implements four independent NC SPST switches using CMOS process technology, supporting dual-supply operation (±4.5V to ±20V) or single-supply (up to +36V). Its logic inputs are +3V compatible (VIH = 2.0V, VIL = 0.8V), eliminating level-shifting in microcontroller-driven control paths.
Each channel features matched on-resistance (ΔRON ≤ 1.5Ω), flat on-resistance over signal range (RFLAT(ON) ≤ 2Ω), and low charge injection (≤30pC), making it suitable for sample-and-hold circuits and multiplexed sensor interfaces where signal integrity and settling time are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 10Ω max - ensures minimal voltage drop and power loss in signal paths carrying up to ±10V at 10mA. |
| On-Resistance Match (ΔRON) | 1.5Ω max - guarantees consistent gain/attenuation across all four channels in differential or multi-path routing. |
| Analog Signal Range | ±15V (dual supply) or 0V to +12V (single supply) - supports rail-to-rail signal switching without clipping. |
| Logic Compatibility | +3V logic - directly interfaces with 3.3V microcontrollers without external level shifters. |
| Turn-On/Off Time | 275ns / 235ns max - enables fast multiplexing in data-acquisition systems sampling at ≥1MHz. |
| Off-Leakage Current | ±2.5nA at +85°C - preserves accuracy in high-impedance sensor and precision reference applications. |
| Crosstalk | >96dB at 20kHz - prevents audible crosstalk in stereo audio routing and adjacent-channel interference in test equipment. |
Pinout & Package
MAX312LCSE+TG52 is housed in a 16-pin narrow SOIC (SO-16) package per package code S16-8, with standard 1.27mm pitch and JEDEC MS-012AC footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | CMOS logic inputs controlling switch state; active-low logic drives NC closure. |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - connected to load/sensor; current flows bidirectionally when switch closed. |
| 3, 6, 11, 14 | NC1–NC4 | Normally closed analog terminals - shorted to COM when IN = 0V; open when IN ≥ 2.0V. |
| 4 | V− | Negative analog supply input - connect to −15V (dual) or GND (single supply). |
| 5 | GND | Digital and analog ground reference - must be low-impedance for noise immunity. |
| 12 | N.C. | No internal connection - leave unconnected; no routing or grounding required. |
| 13 | V+ | Positive analog supply input - accepts +15V (dual) or +12V (single supply); powers analog core. |
Key Features
| Feature | Design Value |
|---|---|
| +3V logic-compatible inputs | VIH = 2.0V, VIL = 0.8V - eliminates need for external level translators when driven by 3.3V FPGAs or MCUs. |
| Rail-to-rail signal handling | Supports analog signals from V− to V+ - enables full dynamic range utilization in ±15V industrial instrumentation. |
| Guaranteed RON flatness | 2Ω max variation over full signal range - maintains linearity in audio and measurement applications. |
| Low charge injection | ≤30pC - minimizes voltage glitch on sampled nodes, critical for precision ADC front-ends. |
| Pin compatibility | Direct replacement for MAX312/MAX313/MAX314 and DG411/DG412/DG413 - simplifies legacy design upgrades. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX312LESE | Extended temperature range (−40°C to +85°C) vs. 0°C to +70°C; identical electrical specs and pinout. | Suitable for automotive or outdoor telecom equipment requiring wider thermal margin. | Select MAX312LESE when operating ambient exceeds +70°C or storage below 0°C is required. |
| ADG411BRZ | Quad SPST, but normally open (NO); 35Ω on-resistance (vs. 10Ω); 3V logic compatible; SO-16 package. | Not functionally interchangeable due to NO vs. NC behavior and higher RON - requires circuit redesign. | Choose ADG411BRZ only if NC functionality is not required and higher on-resistance is acceptable for the signal chain. |
Compared with MAX312LCSE+TG52, MAX312LESE offers identical performance with extended thermal qualification, while ADG411BRZ provides a NO alternative at higher RON and different switching polarity - neither is pin-compatible without layout changes.

FAQ
What is the maximum supply voltage rating for MAX312LCSE+TG52?
The MAX312LCSE+TG52 supports dual supplies from ±4.5V to ±20V and single supplies from +4.5V to +36V. Absolute maximum ratings specify V+ up to +44V and V− down to −44V, but sustained operation above ±20V or +36V violates the guaranteed specifications and risks reliability degradation. Always observe the recommended operating ranges in the datasheet for MAX312LCSE+TG52.
Is MAX312LCSE+TG52 pin-compatible with the legacy MAX312 series?
Yes, MAX312LCSE+TG52 is pin-compatible with MAX312, MAX313, and MAX314 in SO-16, TSSOP, and DIP packages. The L-suffix devices retain identical pinouts and logic behavior while improving on-resistance matching and removing the VL supply requirement. No PCB changes are needed when upgrading from MAX312CSE to MAX312LCSE+TG52.
Does MAX312LCSE+TG52 support single-supply operation with 0V ground reference?
Yes, MAX312LCSE+TG52 operates in single-supply mode with V− tied to GND and V+ ranging from +4.5V to +36V. In this configuration, analog signals swing from 0V to V+, and logic inputs remain +3V compatible. The device maintains rail-to-rail signal handling and specified RON (35Ω max at +12V) under single-supply conditions as confirmed in the Electrical Characteristics table for single-supply operation.
What is the typical on-resistance flatness specification for MAX312LCSE+TG52?
The MAX312LCSE+TG52 guarantees on-resistance flatness (RFLAT(ON)) of 2Ω max over the full analog signal range under dual-supply conditions. This means the difference between maximum and minimum RON values measured across VCOM = −15V to +15V remains ≤2Ω, ensuring consistent signal attenuation regardless of input voltage - a key parameter for precision audio and measurement applications using MAX312LCSE+TG52.
Can MAX312LCSE+TG52 be used in audio applications requiring low THD?
Yes, MAX312LCSE+TG52 is explicitly characterized for low-distortion audio: THD is ≤0.01% at 1kHz with 600Ω loads and ±10V signals. Its low RON (10Ω max), tight RON matching (1.5Ω max), and low charge injection (≤30pC) minimize harmonic generation and switching transients - making it suitable for professional audio routing, headset switching, and codec interface applications where MAX312LCSE+TG52's performance meets AES17-compliant requirements.
