Product details
Overview
MAX312ESE+TG002 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, and 2.5nA max off-leakage at +85°C - enabling high-fidelity audio switching and low-error data acquisition.
For engineers reviewing the MAX312ESE+TG002 datasheet, MAX312ESE+TG002 pinout, MAX312ESE+TG002 application, or MAX312ESE+TG002 equivalent, key selection criteria include guaranteed RON flatness (2Ω max), >96dB crosstalk at 20kHz, ESD tolerance >2000V per Method 3015.7, and compatibility with ±4.5V to ±20V dual supplies or +4.5V to +30V single supplies.
Technical Context
The MAX312ESE+TG002 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 high, 0.8V low) independent of analog supply rails.
It features integrated overvoltage protection diodes on all analog terminals (COM, NC, NO), clamping signals beyond V+ or V−, and supports break-before-make timing only in the MAX314 variant - not applicable to MAX312ESE+TG002, which operates as four independent NC switches without inter-channel timing coordination.
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 difference between any two channels - critical for matched gain/phase in multi-channel instrumentation. |
| Analog Signal Range | Rail-to-rail: V− to V+ - supports full dynamic range signal switching without clipping in ±15V or +12V systems. |
| 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 or measurable interference between adjacent audio or measurement channels. |
| ESD Protection | >2000V per Method 3015.7 - enables robust handling in manufacturing and field-replaceable test equipment. |
| Supply Range | +4.5V to +30V (single) or ±4.5V to ±20V (dual) - simplifies power architecture across industrial and avionics platforms. |
Pinout & Package
MAX312ESE+TG002 is housed in a 16-pin narrow SOIC (SO) package (JEDEC MS-012, 3.9mm width), RoHS-compliant and rated for -40°C to +85°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Logic control inputs; active-low logic sense for NC function - '0' closes switch, '1' opens. |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - bidirectional signal path connection point for each switch. |
| 3, 6, 11, 14 | NC1–NC4 | Normally closed analog terminals - shorted to COM when IN = 0; open when IN = 1. |
| 4 | V− | Negative analog supply - connect to GND for single-supply operation; sets lower rail for analog signal range. |
| 5 | GND | Logic ground reference - separate from analog supplies to minimize noise coupling into digital control path. |
| 12 | VL | Logic supply voltage - powers input buffers; typically +5V, independent of V+/V− rails. |
| 13 | V+ | Positive analog supply - defines upper rail for analog signal range and internal biasing. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without distortion or clipping - essential for ±10V industrial I/O and audio line-level routing. |
| Guaranteed RON flatness | ≤2Ω max variation over full signal range - maintains consistent gain and THD across amplitude, critical for low-distortion audio. |
| Low charge injection | ±30pC max - minimizes voltage glitch on sampled nodes in data acquisition and hold circuits. |
| Pin compatibility with DG411 | Direct replacement for industry-standard DG411 footprint and logic behavior - reduces redesign effort in legacy test equipment upgrades. |
| High off-isolation | ≥65dB at 1MHz - effectively blocks unwanted signal coupling between inactive channels in multiplexed systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX312ESE | Same die, identical electrical specs and pinout; TG002 suffix indicates tape-and-reel packaging per Aetrix standard logistics protocol. | No functional difference - both support same operating conditions, timing, and signal integrity. | Select MAX312ESE+TG002 for automated SMT assembly; MAX312ESE (bulk) for prototyping or manual placement. |
| ADG411BRZ | Pin-compatible but higher RON (35Ω typ), wider RON match (5Ω max), and no guaranteed rail-to-rail performance below V− + 2V. | Less suitable for low-distortion audio or high-precision DC-coupled acquisition due to higher on-resistance and limited signal range. | Choose ADG411BRZ only if legacy board layout mandates exact footprint and system tolerances accommodate higher RON and leakage. |
Compared with MAX312ESE and ADG411BRZ, MAX312ESE+TG002 provides superior signal fidelity (6.5Ω vs. 35Ω RON, rail-to-rail vs. limited range) and tighter matching (1.5Ω vs. 5Ω), making it optimal for high-accuracy test, audio, and avionics applications where channel consistency and low distortion are design-critical.
