Product details

Overview

The MAX4311EEE+ from Maxim Integrated is a 4-channel, single-supply video multiplexer-amplifier with adjustable-gain amplifier optimized for unity-gain stability, 345MHz −3dB bandwidth, 430V/µs slew rate, and rail-to-rail output driving capability into 150Ω loads - deployed in broadcast video signal routing and high-speed analog switching systems.

For engineers reviewing the MAX4311EEE+ datasheet, MAX4311EEE+ pinout, MAX4311EEE+ application, or MAX4311EEE+ equivalent, key selection criteria include channel count (4), gain configuration (≥+1V/V), switching transient (10mV_p-p), differential gain/phase error (0.06%/0.08°), and QSOP-16 package compatibility with video crosspoint and flash ADC buffer designs.

Technical Context

The MAX4311EEE+ integrates a 4:1 analog multiplexer with an external-feedback, voltage-feedback amplifier optimized for closed-loop gains ≥+1V/V. Its input common-mode range extends to the negative rail (VEE), enabling ground-sensing operation in single-supply +4V to +10.5V systems.

It delivers 345MHz −3dB bandwidth and 430V/µs slew rate while maintaining ultra-low 40ns channel switching time and 10mV_p-p switching transients - critical for preserving NTSC/PAL timing integrity and minimizing ghosting in composite video paths.

Key Specifications

Slew Rate	430V/µs - ensures distortion-free reproduction of fast video edges (e.g., sync pulses)
Channel Switching Time	40ns - enables glitch-free source switching in real-time video matrix applications
Differential Gain/Phase Error	0.06% / 0.08° - meets broadcast-grade color fidelity requirements per SMPTE RP-168
Quiescent Supply Current	6.9mA - enables low-power operation in multi-channel video processing modules
Input Common-Mode Range	VEE to VCC − 2.8V - allows DC-coupled input from ground-referenced video sources
Rail-to-Rail Output Swing	Within 730mV of VCC and 30mV of VEE into 150Ω - drives standard 75Ω coaxial lines with back-termination

Pinout & Package

MAX4311EEE+ is housed in a 16-pin QSOP package (5.3mm × 10.2mm, 0.635mm pitch), optimized for high-density video routing PCBs with thermal and EMI performance suitable for industrial and broadcast equipment.

Pin	Circuit Role	Design Meaning
1	A0	LSB channel select address input; TTL/CMOS-compatible logic control for 4:1 mux
2	A1	MSB channel select address input; enables deterministic input routing without software overhead
3	SHDN	Active-low shutdown control; reduces ICC to 560µA and places OUT in high-Z state
4	VCC	Positive supply rail (+4V to +10.5V); bypassing with 100nF ceramic capacitor required
5	IN0	Channel 0 analog input; 2pF input capacitance (constant on/off) minimizes source loading
6	IN1	Channel 1 analog input; matched to IN0 for gain/phase tracking across channels
7	IN2	Channel 2 analog input; supports simultaneous multi-source monitoring in security DVRs
8	IN3	Channel 3 analog input; fully isolated when deselected (−82dB off-isolation @10MHz)
9	OUT	Amplified, multiplexed output; rail-to-rail capable with 8Ω open-loop output impedance
10	FB	Inverting feedback node; external RF/RG network sets closed-loop gain ≥+1V/V
11–12	N.C.	No-connect pins; tie to ground plane for optimal EMI suppression and thermal conduction
13–14	GND	Dual ground connections; separate return paths reduce ground bounce in high-speed switching
15–16	VEE	Negative supply / ground reference; supports single-supply operation with true ground-sensing inputs

Key Features

Feature	Design Value
40ns channel switching	Enables sub-microsecond video source arbitration in broadcast switchers without visible artifacts
10mV_p-p switching transient	Prevents luminance "glitch" during active video line transitions in SD/HD-SDI infrastructure
0.06% differential gain error	Preserves color saturation accuracy across full 0–5.5MHz NTSC luminance band
Rail-to-rail output into 150Ω	Drives dual-terminated 75Ω coaxial cables directly without external level-shifting circuitry
Input common-mode range to VEE	Accepts DC-coupled CVBS or Y/C signals referenced to system ground without AC coupling capacitors

Equivalent & Alternatives

The following parts are listed as comparable options for similar video multiplexer-amplifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MAX4311ESD+	Same electrical specs; packaged in 14-pin narrow SO instead of 16-pin QSOP	Requires PCB layout change due to different footprint and pinout; no N.C. pins	Select for legacy SO-based designs where board space permits larger body size and lower thermal resistance
THS4302DR	Single-channel, 1.8GHz GBW, no integrated mux; requires external 4:1 analog switch	Higher bandwidth but lacks integrated multiplexing; increases component count and layout complexity	Choose only when >1GHz small-signal bandwidth is mandatory and discrete mux integration is acceptable

Compared with MAX4311ESD+, the MAX4311EEE+ offers identical analog performance in a smaller QSOP-16 footprint with dedicated N.C. pins for grounding - improving EMI immunity in dense video routing boards. Versus THS4302DR, it trades raw bandwidth for integrated 4:1 switching, reducing BOM count and interconnect parasitics in multi-source video systems.

FAQ

What is the maximum operating supply voltage for the MAX4311EEE+?

The MAX4311EEE+ operates from a single supply of +4.0V to +10.5V or dual supplies of ±2.0V to ±5.25V. Absolute maximum supply voltage (VCC to VEE) is 12V. Exceeding this may cause permanent damage. The device maintains specified performance across its full operating range, including rail-to-rail output swing and 345MHz bandwidth at both extremes.

Does the MAX4311EEE+ support DC-coupled video inputs?

Yes, the MAX4311EEE+ supports DC-coupled video inputs because its input common-mode voltage range extends to the negative supply rail (VEE). In single-supply operation with VEE = GND, this allows direct connection of ground-referenced CVBS or Y/C signals without AC coupling capacitors - preserving low-frequency response and eliminating baseline shift in composite video.

How does the MAX4311EEE+ achieve low switching transients during channel selection?

The MAX4311EEE+ achieves 10mV_p-p switching transients through matched transistor pairs in its internal 4:1 multiplexer and charge-balanced switching architecture. This minimizes injected charge during channel transitions, preventing visible "glitches" in active video lines. The design also maintains constant 2pF input capacitance regardless of channel state, reducing source disturbance.

Can the MAX4311EEE+ drive a 75Ω coaxial cable directly?

Yes, the MAX4311EEE+ can drive a 75Ω coaxial cable directly when configured with proper back-termination. Its rail-to-rail output swings within 730mV of VCC and 30mV of VEE into a 150Ω load - matching the parallel combination of 75Ω cable and 75Ω termination resistor. This eliminates need for external level-shifting or buffering stages in standard video line driver configurations.

What is the function of the FB pin on the MAX4311EEE+?

On the MAX4311EEE+, the FB (feedback) pin is the inverting input of the integrated amplifier, used with external RF and RG resistors to set closed-loop gain ≥+1V/V. Unlike fixed-gain variants (e.g., MAX4314), the MAX4311EEE+ relies on this external network for gain control and stability optimization - requiring careful layout to minimize stray capacitance and avoid peaking in frequency response.
