Product details
Overview
MAX4447ESE+ from Maxim Integrated is a single-ended-to-differential line driver IC optimized for high-speed video and RF signal transmission. It features a fixed +2V/V gain, 430MHz small-signal bandwidth, 6500V/µs slew rate, ±6.2V differential output swing into 50Ω, and active enable control-enabling use in coaxial-to-twisted-pair conversion and xDSL line driving.
For engineers reviewing the MAX4447ESE+ datasheet, MAX4447ESE+ pinout, MAX4447ESE+ application, or MAX4447ESE+ equivalent, key selection criteria include guaranteed 0.1dB gain flatness to 200MHz, ultra-low differential gain/phase error (0.01%/0.02°), 23nV/√Hz input noise density at 1MHz, and low-power enable mode reducing quiescent current below 5.5mA.
Technical Context
The MAX4447ESE+ employs current-feedback amplifier (CFA) architecture to achieve wide bandwidth and high slew rate without sacrificing stability. Its fixed internal gain network eliminates external resistor dependencies while maintaining <2% gain error across temperature and output range.
It operates from dual ±5V supplies, delivers 130mA output drive current, and integrates TTL-compatible enable logic that places outputs in high-impedance state when disabled-supporting dynamic power management in multi-channel line driver systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar single-ended-to-differential line driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4448ESE+ | Variable gain ≥+2V/V via external RG; 330MHz small-signal bandwidth; lower slew rate (4300V/µs) | Better suited for programmable-gain systems requiring flexibility over fixed gain | Select MAX4448ESE+ only if gain adjustment is needed; MAX4447ESE+ offers superior bandwidth and slew rate at fixed gain |
| THS3201DGN | Current-feedback architecture; 440MHz bandwidth; ±6V swing; no integrated enable pin | Lacks enable function and differential phase/gain specs optimized for video; requires external level-shifting | Choose THS3201DGN for higher supply voltage operation (±15V) but accept added complexity and missing video-grade linearity |
Compared with MAX4448ESE+, MAX4447ESE+ provides 100MHz more bandwidth and 2200V/µs higher slew rate at fixed gain, making it preferable for high-fidelity video and broadband RF. Versus THS3201DGN, MAX4447ESE+ integrates enable logic and guarantees broadcast-grade differential linearity without external components.

FAQ
What is the operating supply voltage range for the MAX4447ESE+?
The MAX4447ESE+ operates from dual ±4.5V to ±5.5V supplies, with typical performance characterized at ±5V. This range ensures compatibility with standard analog signal chain rails and allows margin for ripple and tolerance. The device maintains specified bandwidth, slew rate, and output swing across the full range, and its PSRR exceeds 53dB to reject supply noise.
Does the MAX4447ESE+ require external gain-setting resistors?
No, the MAX4447ESE+ has an internally fixed +2V/V gain configuration. Pin 4 (RG) is a no-connect for this variant and must be left unconnected or tied to GND for optimal AC performance. Unlike the MAX4448ESE+ and MAX4449ESE+, the MAX4447ESE+ does not support external gain adjustment-simplifying layout and eliminating resistor tolerance errors.
How does the enable function affect output behavior in the MAX4447ESE+?
When the EN pin is driven low (≤0.8V), the MAX4447ESE+ enters low-power mode: quiescent current drops below 5.5mA and both OUT+ and OUT− outputs enter a high-impedance state. This prevents loading of downstream circuitry and enables dynamic power gating. Rise/fall times for enable/disable transitions are 55ns and 660ns respectively, supporting burst-mode operation in time-division systems.
What load conditions deliver the rated ±6.2V differential output swing for the MAX4447ESE+?
The ±6.2V differential output swing is specified with ±5V supplies and a 50Ω differential load (i.e., 25Ω from each output to ground). Under these conditions, the MAX4447ESE+ delivers full-scale swing while maintaining linearity and distortion specs. With lighter loads (e.g., 100Ω), swing increases slightly; with heavier loads or mismatched terminations, swing and bandwidth degrade predictably per the RL vs. VOUT curve in the datasheet.
Is the MAX4447ESE+ suitable for driving 75Ω coaxial cables directly?
Yes-the MAX4447ESE+ can drive 75Ω coaxial cables directly when configured as a differential-to-single-ended interface using a center-tapped transformer or resistive hybrid. Its 50Ω differential output impedance matches common balun inputs, and its 130mA output current supports drive into unterminated or lightly loaded 75Ω lines. For longest reach, use with proper termination and consider adding series isolation resistors to damp ringing on long traces.
