Product details
Overview
The MAX4312ESE+T from Maxim Integrated is an 8-channel, unity-gain-stable video multiplexer-amplifier optimized for broadcast-quality signal routing. It delivers 265MHz -3dB bandwidth, 345V/µs slew rate, 40ns channel switching time, and 0.06%/0.08° differential gain/phase error-enabling high-fidelity SD/HD video switching in professional AV equipment.
For engineers reviewing the MAX4312ESE+T datasheet, MAX4312ESE+T pinout, MAX4312ESE+T application, or MAX4312ESE+T equivalent, key selection criteria include rail-to-rail output swing into 150Ω, input common-mode range extending to VEE, low 10mVp-p switching transients, and shutdown current of 560µA for power-sensitive video matrix designs.
Technical Context
The MAX4312ESE+T integrates an 8-input analog multiplexer with a voltage-feedback amplifier configured for adjustable closed-loop gain ≥+1V/V. Its internal architecture maintains 8Ω open-loop output impedance across full output swing, minimizing load-dependent gain error and bandwidth variation typical of rail-to-rail amplifiers.
It supports single-supply operation from +4V to +10.5V (or ±2V to ±5.25V dual), features logic-compatible address inputs (A0–A2) and SHDN control, and achieves 73–95dB CMRR over 0–2.2V common-mode range-critical for rejecting noise in multi-source video systems.
Key Specifications

Pinout & Package
The MAX4312ESE+T is housed in a 16-pin narrow SO package (body width 3.9mm), compatible with standard SOIC-16 footprints and reflow assembly processes.
| Pin/Terminal | Circuit Role | Design Meaning |

| SHDN | Active-low shutdown control | Pulls outputs to high-impedance and reduces ICC to 560µA when ≤VEE+1V |
| VCC, VEE | Positive/negative supply pins | Support single (+4V to +10.5V) or dual (±2V to ±5.25V) operation; VEE = GND in single-supply mode |
| IN0–IN7 | Analog multiplexer inputs | Eight independent video input channels; 2pF total input capacitance (on/off stable) |
| OUT | Amplified output | Rail-to-rail output stage capable of ±95mA drive into 30Ω; 8Ω open-loop ZOUT |
| GND | Ground reference | Low-impedance return path; requires solid ground plane per high-speed layout guidelines |
Key Features

IC Role / Device Role / Timing Role: Fan-out amplifier with individually selectable outputs, allowing dynamic assignment of reference feeds per encoder. Use Value: Maintains 0.08° differential phase error across all channels, preventing chroma misalignment in encoded MPEG-2/4 streams. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar video multiplexer-amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4312EEE+ | Same electrical specs; packaged in 16-pin QSOP (4.4mm width) instead of narrow SO (3.9mm) | Requires different land pattern and stencil; slightly higher parasitic inductance due to longer lead frames | Select for legacy QSOP board compatibility or where thermal dissipation margin exceeds narrow SO limits |
| THS4521IDR | Single-channel, fully differential amplifier; no integrated multiplexer; 2.1GHz GBW vs. 265MHz | Requires external 8:1 analog switch and level-shifting; superior SNR but no channel switching capability | Select when differential signaling, ultra-low noise (<2.3nV/√Hz), or >1GSPS sampling is required |
Compared with MAX4312EEE+ and THS4521IDR, the MAX4312ESE+T uniquely combines 8:1 multiplexing, unity-gain stability, and broadcast-grade video fidelity in a space-constrained narrow SO package-making it optimal for cost- and size-sensitive multichannel video routing where integrated switching is mandatory.

FAQ
What supply voltage range does the MAX4312ESE+T support?
The MAX4312ESE+T operates from a single +4V to +10.5V supply or dual ±2V to ±5.25V supplies. In single-supply mode, VEE is connected to ground. This wide range allows direct integration with 5V or 3.3V system rails while maintaining full video bandwidth and output swing specifications across the entire range.
How does the MAX4312ESE+T achieve low differential gain/phase error?
The MAX4312ESE+T achieves 0.06% differential gain and 0.08° differential phase error through precision trimming of its voltage-feedback amplifier core, combined with constant 2pF input capacitance regardless of channel state and 8Ω open-loop output impedance. These characteristics minimize nonlinearities and load-dependent frequency response shifts that degrade color fidelity in composite and component video signals.
Can the MAX4312ESE+T drive 75Ω coaxial cables directly?
Yes-the MAX4312ESE+T drives 75Ω coaxial cables directly when used with proper back-termination. Its rail-to-rail output swings within 730mV of VCC and 30mV above VEE into 150Ω, enabling clean 1Vpp signal delivery into a 75Ω load with 75Ω series termination at the driver and 75Ω shunt termination at the receiver-meeting SMPTE 259M impedance and signal integrity requirements.
What is the function of the FB pin on the MAX4312ESE+T?
The MAX4312ESE+T does not have an FB (feedback) pin. Unlike the MAX4310/MAX4311 variants, the MAX4312ESE+T uses an internally compensated amplifier optimized for unity-gain stability. External feedback resistors are not required or supported; gain adjustment is achieved only via external passive networks at the output stage, preserving stability and bandwidth.
Is the MAX4312ESE+T pin-compatible with other members of the MAX4310–MAX4315 family?
No-the MAX4312ESE+T is not pin-compatible with MAX4310 or MAX4311 due to differing channel counts and pin assignments. While all share the same 16-pin narrow SO footprint, the MAX4312ESE+T uses pins 1–3 for A0–A2 and pins 4–13 for IN0–IN7, whereas MAX4311 uses only four inputs and repurposes several pins. Always verify pin mapping against the specific device's datasheet diagram.
