Product details
Overview
MAX4312ESE from Maxim Integrated is an 8-channel, unity-gain-stable video multiplexer-amplifier with 265MHz -3dB bandwidth, 345V/µs slew rate, and 40ns channel switching time. It operates from a single +4V to +10.5V supply, delivers rail-to-rail output swing into 150Ω, and achieves 0.06% differential gain / 0.08° differential phase error-optimized for broadcast video signal routing.
For engineers reviewing the MAX4312ESE datasheet, MAX4312ESE pinout, MAX4312ESE application, or MAX4312ESE equivalent, key selection criteria include multichannel video switching transient suppression (10mVp-p), input common-mode range extending to VEE, low-power shutdown (560µA), and compatibility with 75Ω back-terminated cable drivers in high-density analog matrix systems.
Technical Context
The MAX4312ESE 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 features logic-controlled channel selection via A0–A2 address inputs, SHDN-driven shutdown with high-impedance output state, and constant 2pF input capacitance regardless of channel on/off state-ensuring predictable source loading and stable AC performance during switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| -3dB Bandwidth | 265MHz - supports full NTSC/PAL composite video and HD component video bandwidths without attenuation |
| Slew Rate | 345V/µs - enables clean 2Vp-p pulse response with <35ns settling to 0.1% |
| Channel Switching Time | 40ns - minimizes visible glitches during real-time video source switching |
| Switching Transient | 10mVp-p - ensures sub-1% amplitude disturbance at output during channel change |
| Differential Gain/Phase Error | 0.06% / 0.08° - meets broadcast-grade color fidelity requirements per SMPTE RP-168 |
| Supply Voltage Range | +4V to +10.5V single supply - eliminates need for negative rail in portable or space-constrained video equipment |
| Quiescent Current | 7.4mA - balances high-speed performance with thermal management in multi-device arrays |
Pinout & Package
MAX4312ESE is housed in a 16-pin narrow SO package (5.3mm × 10.2mm, 1.27mm pitch), optimized for high-density PCB layouts in video routing hardware.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0, A1, A2 | Binary channel address inputs | Select one of eight analog inputs (IN0–IN7); TTL/CMOS compatible with VIL ≤ VEE+1V, VIH ≥ VCC−1V |
| SHDN | Active-low shutdown control | Pulls output to high-impedance state and reduces ICC to 560µA; must be tied to VCC if unused |
| VCC, VEE | Positive/negative supply pins | Support single-supply operation (VEE = GND) or dual ±2V to ±5.25V; VEE serves as reference ground |
| IN0–IN7 | Analog multiplexer inputs | Eight independent video signal inputs; each exhibits 2pF constant input capacitance regardless of switch state |
| OUT | Amplified multiplexer output | Rail-to-rail output capable of driving 150Ω loads to within 730mV of rails; open-loop ZOUT = 8Ω |
| GND | Ground reference | Primary return path for supply and signal currents; requires low-impedance plane connection per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| 8-channel video multiplexing + unity-gain amplifier | Enables compact, single-chip routing of multiple SD/HD video sources without external gain stages |
| 40ns channel switching with 10mVp-p transient | Eliminates visible "glitch" artifacts during live video switching in broadcast switchers and medical imaging displays |
| Rail-to-rail output into 150Ω | Delivers full-swing video signals directly to 75Ω coaxial cables with proper termination, avoiding level-shifting circuitry |
| Input common-mode range to VEE | Accepts ground-referenced video signals (e.g., CVBS, Y/C) without level-shifting or clamping networks |
| Low-power shutdown mode (560µA) | Allows dynamic power gating in multi-amp matrices, reducing system-level thermal load and enabling hot-swap capability |

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 345MHz bandwidth and identical gain architecture | Lower channel count reduces PCB footprint but requires two devices for 8-input systems | Select when system requires fewer inputs and higher bandwidth per channel |
| MAX4315ESE | 8-channel device with fixed +2V/V gain and 97MHz bandwidth | Optimized for driving back-terminated 75Ω cables, not unity-gain video buffering | Select only when fixed 6dB gain and cable-driving capability are required over unity-gain stability |
Compared with MAX4311EEE and MAX4315ESE, the MAX4312ESE uniquely balances 8-channel count, unity-gain stability, and 265MHz bandwidth-making it the only direct fit for high-channel-count, broadcast-grade video multiplexing where gain flexibility and differential error performance are critical.

FAQ
What is the maximum operating supply voltage for MAX4312ESE?
The MAX4312ESE supports a single-supply operating range of +4V to +10.5V, or dual supplies of ±2V to ±5.25V. Absolute maximum supply voltage is 12V (VCC to VEE). Exceeding +10.5V in single-supply mode risks violating internal biasing constraints and may degrade differential phase performance beyond specification.
Does MAX4312ESE require external gain-setting resistors?
Yes, the MAX4312ESE uses external feedback (RF) and gain-setting (RG) resistors to configure closed-loop gain ≥+1V/V. Unlike the fixed +2V/V MAX4315ESE, the MAX4312ESE's amplifier is optimized for unity-gain stability but requires external resistor networks-e.g., RF = RG = 500Ω for +2V/V noninverting configuration per Table 1 in the datasheet.
What is the input common-mode voltage range of MAX4312ESE?
The MAX4312ESE accepts input voltages from VEE to (VCC − 2.8V) under typical conditions. This extends to the negative rail (VEE), enabling direct interface with ground-referenced video signals like CVBS or Y/C without clamping or level-shifting circuitry-critical for maintaining DC brightness/contrast integrity in medical imaging.
Can MAX4312ESE drive 75Ω coaxial cables directly?
Yes, the MAX4312ESE can drive 75Ω coaxial cables when properly terminated at both ends (source and load). Its rail-to-rail output delivers full-swing video into 150Ω (two 75Ω in parallel), and its low 8Ω open-loop output impedance ensures minimal gain error under reactive loads-provided layout follows microstrip guidelines and bypass capacitors (100nF ceramic near VCC/VEE) are used.
How does shutdown mode affect the output state of MAX4312ESE?
When SHDN is driven low, the MAX4312ESE disables its output amplifier and places the OUT pin in a high-impedance state (typical 35kΩ), while reducing quiescent supply current to 560µA. This allows multiple MAX4312ESE devices to share a common output bus-only the active device drives the line, eliminating contention and enabling scalable video matrix architectures.
