Product details
Overview
The MAX4312EEE from Maxim Integrated is an 8-channel, single-supply video multiplexer-amplifier with adjustable-gain amplifier optimized for unity-gain stability, -3dB bandwidth of 265MHz, 345V/µs slew rate, and 40ns channel switching time. It operates from +4V to +10.5V single supply or ±2V to ±5.25V dual supplies, features rail-to-rail outputs, and delivers broadcast-grade video performance in 16-pin QSOP package.
For engineers reviewing the MAX4312EEE datasheet, MAX4312EEE pinout, MAX4312EEE application, or MAX4312EEE equivalent, key selection criteria include its 8:1 analog video multiplexing capability, differential gain/phase error (0.06%/0.08°), low 10mVp-p switching transient, 7.4mA quiescent current, and compatibility with 75Ω back-terminated video cabling systems.
Technical Context
The MAX4312EEE integrates an 8-input analog multiplexer with a high-speed, unity-gain-stable voltage-feedback amplifier. Its internal architecture supports rail-to-rail output swing (within 730mV of rails into 150Ω), input common-mode range extending to the negative rail, and open-loop output impedance of only 8Ω across full output voltage range - minimizing load-dependent gain error and bandwidth variation.
Channel selection is controlled via three logic inputs (A0–A2), enabling deterministic 40ns switching with ultra-low 10mVp-p transient artifacts. The device includes a dedicated shutdown pin (SHDN) that reduces supply current to 560µA and places the output in high-impedance state, supporting matrix expansion via paralleled outputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| -3dB Bandwidth | 265MHz - supports full NTSC/PAL/HD-SDI baseband video signal fidelity without attenuation |
| Slew Rate | 345V/µs - enables clean 2Vp-p step response at >100MHz, critical for sharp video edge integrity |
| Channel Switching Time | 40ns - ensures minimal disruption during real-time video source switching |
| Differential Gain/Phase Error | 0.06% / 0.08° - meets broadcast video color fidelity requirements per SMPTE 253M |
| Quiescent Supply Current | 7.4mA - balances high-speed performance with power efficiency in portable or thermally constrained systems |
| Input Common-Mode Range | Extends to VEE - allows direct interface with ground-referenced video sources without level-shifting circuitry |
| Rail-to-Rail Output Swing | Within 730mV of rails into 150Ω - maximizes dynamic range for 1Vp-p video signals on standard coaxial infrastructure |
Pinout & Package
MAX4312EEE is housed in a 16-pin QSOP (Quarter-Size Outline Package) with 0.154" body width and 0.025" pitch, optimized for high-density video routing PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0, A1, A2 | Channel address inputs | Binary-select one of eight analog inputs; TTL/CMOS compatible with VIL ≤ VEE+1V, VIH ≥ VCC−1V |
| SHDN | Shutdown control | Active-low enable; pulls output to high-Z and reduces ICC to 560µA when asserted |
| VCC, VEE | Power supply pins | Support single-supply (+4V to +10.5V) or dual-supply (±2V to ±5.25V) operation; VEE = GND in single-supply mode |
| IN0–IN7 | Analog multiplexer inputs | Eight independent video input channels; each exhibits constant 2pF input capacitance regardless of switch state |
| OUT | Amplified output | Rail-to-rail output capable of driving 150Ω loads directly; open-loop ZOUT = 8Ω minimizes gain error vs. load |
| GND | Ground reference | Primary return path; requires low-impedance connection to minimize noise coupling in high-frequency video paths |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar video multiplexer-amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4311EEE | 4-channel version with higher 345MHz -3dB bandwidth and identical 0.06%/0.08° video fidelity | Lower channel count suits 4-input video switchers; reduced pin count eases layout but increases IC count for 8-channel systems | Select when system requires fewer inputs and maximum small-signal bandwidth is prioritized over channel density |
| MAX4314EEE | 4-channel fixed +2V/V gain amplifier with 127MHz bandwidth and 0.09% differential gain error | Fixed gain architecture eliminates external feedback resistors but sacrifices flexibility for unity-gain or variable-gain configurations | Choose for back-terminated cable driving where fixed +2V/V gain matches line loss compensation needs |
Compared with MAX4311EEE and MAX4314EEE, the MAX4312EEE provides optimal trade-off between channel count (8), bandwidth (265MHz), and video fidelity (0.06%/0.08°), making it uniquely suited for high-density broadcast-grade video routing where both scalability and signal integrity are critical.

FAQ
What is the operating supply voltage range for the MAX4312EEE?
The MAX4312EEE operates from a single +4V to +10.5V supply or dual ±2V to ±5.25V supplies. In single-supply configuration, VEE is connected to ground. This wide voltage range allows flexible integration into legacy 5V systems and modern low-voltage embedded platforms while maintaining full AC performance including 265MHz bandwidth and rail-to-rail output swing.
Does the MAX4312EEE require external gain-setting resistors?
Yes, the MAX4312EEE uses external feedback (RF) and input (RG) resistors to set closed-loop gain, as it features an adjustable-gain amplifier optimized for unity-gain stability. Unlike the fixed +2V/V MAX4314EEE, the MAX4312EEE supports noninverting gains ≥+1V/V. Recommended resistor values (e.g., RF = RG = 500Ω for AV = +2V/V) are specified in the datasheet to ensure stability and optimal bandwidth.
How does the MAX4312EEE handle video signal integrity during channel switching?
The MAX4312EEE achieves 40ns channel switching time with only 10mVp-p switching transients, preventing visible glitches in composite or S-Video outputs. Its constant 2pF input capacitance across all states and low 0.06%/0.08° differential gain/phase error preserve color fidelity and luminance timing - critical for broadcast compliance and professional video monitoring applications using the MAX4312EEE.
Can multiple MAX4312EEE devices be paralleled for larger video matrices?
Yes, the MAX4312EEE's shutdown pin (SHDN) places the output in high-impedance state with ~35kΩ disabled output resistance, enabling safe paralleling of multiple devices. By enabling only one MAX4312EEE at a time while others are in shutdown, designers can construct scalable 16×N or 24×N video matrices without bus contention or signal degradation - a capability confirmed in the MAX4312EEE's functional description and application circuits.
What package type is used for the MAX4312EEE and why is it suitable for video applications?
The MAX4312EEE uses a 16-pin QSOP package with 0.025" lead pitch and 0.154" body width. This package offers superior high-frequency performance versus SOIC due to shorter lead lengths and lower parasitic inductance - essential for preserving 265MHz bandwidth and minimizing signal reflections in 75Ω video routing. Its thermal characteristics also support sustained operation in dense video processing assemblies.
