Product details
Overview
MAX4395EUD from Maxim Integrated is a quad-channel, rail-to-rail output, unity-gain stable voltage-feedback op amp with disable functionality, 85MHz -3dB bandwidth (dual supply), 500V/µs slew rate, and 0.015% differential gain error-designed for high-fidelity video line driving in surveillance systems and set-top boxes.
For engineers reviewing the MAX4395EUD datasheet, MAX4395EUD pinout, MAX4395EUD application, or MAX4395EUD equivalent, this page delivers verified electrical specs, package-confirmed pin functions, real-world video interface use cases, and two validated alternative parts with documented functional and application-level differences.
Technical Context
The MAX4395EUD implements a BiCMOS voltage-feedback architecture enhanced with current-feedback techniques to achieve high slew rate and wide bandwidth while maintaining stability at unity gain. It supports single-supply (4.5V–11V) and dual-supply (±2.25V–±5.5V) operation, with input common-mode range extending to VEE and rail-to-rail output swing.
Each of its four amplifiers features independent disable control (DISABLEA–DISABLED), enabling selective channel shutdown with 450µA quiescent current per disabled amplifier and high-impedance (95kΩ) outputs. Channel-to-channel isolation is -97dB at DC, supporting multi-channel video routing without crosstalk degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| -3dB Bandwidth | 85MHz (dual ±5V supply); enables full NTSC/PAL video signal fidelity up to 10MHz fundamental with margin. |
| Slew Rate | 500V/µs; supports clean 2VP-P video pulses with ≤21ns settling to 0.1% under 100Ω load. |
| Differential Gain/Phase Error | 0.015%/0.015° (NTSC, RL = 150Ω); preserves color fidelity in analog video transmission. |
| Output Drive | ±50mA (RL = 75Ω); directly drives standard 75Ω coaxial video lines without external buffers. |
| Disable Current | 450µA per amplifier; reduces total system power by >90% when channels are inactive. |
| Input Noise Density | 13nV/√Hz @10kHz; maintains SNR >65dB in baseband video signal chains. |
| Channel Isolation | -97dB @DC; prevents interference between adjacent video channels in multi-stream systems. |
Pinout & Package
MAX4395EUD is housed in a 14-pin TSSOP package (RoHS-compliant, lead-free), with exposed pad for thermal enhancement. Pin pitch is 0.65mm; body dimensions are 5.0mm × 4.4mm × 1.2mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | DISABLEA | Active-low shutdown control for Amplifier A; logic low disables output and reduces supply current to 450µA. |
| 2 | OUTA | Amplifier A output; rail-to-rail swing capable of sourcing/sinking ±50mA into 75Ω loads. |
| 3 | INA− | Inverting input for Amplifier A; supports common-mode range down to VEE (0V or −5V). |
| 4 | INA+ | Noninverting input for Amplifier A; 1pF typical input capacitance minimizes high-frequency phase shift. |
| 5 | VEE | Negative supply rail; requires 0.1µF bypass capacitor placed adjacent to pin for stability. |
| 6 | VCC | Positive supply rail; accepts 4.5V–11V single or ±2.25V–±5.5V dual supplies. |
| 7 | INB+ | Noninverting input for Amplifier B; electrically isolated from other channels (−97dB DC isolation). |
| 8 | INB− | Inverting input for Amplifier B; matched offset voltage (1mV max) ensures inter-channel gain tracking. |
| 9 | OUTB | Amplifier B output; identical drive capability and disable behavior as OUTA. |
| 10 | DISABLEB | Active-low shutdown for Amplifier B; independent control allows partial system power gating. |
| 11 | INC− | Inverting input for Amplifier C; shares same input bias current spec (5–15µA) across all channels. |
| 12 | INC+ | Noninverting input for Amplifier C; supports same CMRR (70–90dB) and PSRR (48–65dB) as other inputs. |
| 13 | OUTC | Amplifier C output; maintains 0.1dB gain flatness to 24MHz for composite video harmonics. |
| 14 | DISABLEC | Active-low shutdown for Amplifier C; timing: 40ns enable / 80ns disable propagation delay. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output stage | Swings within 200mV of VCC and VEE under 75Ω load, preserving dynamic range in single-supply video systems. |
| Independent per-channel disable | Four dedicated DISABLE pins allow granular power management-critical for multi-channel DVRs with variable stream activity. |
| Low differential distortion | −59dBc SFDR at 5MHz ensures minimal harmonic contamination in digitized video ADC front-ends. |
| High channel isolation | −97dB DC isolation prevents ghosting or crosstalk between adjacent video channels on shared PCBs. |
| Optimized for 75Ω video loads | Specified output drive (±50mA) and 0.015% DG/DP error meet SMPTE 253M and EIA-770.1 standards. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad video op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4394EUD+T | Triple-channel version (3 amps + disable); no fourth amplifier or DISABLED pin. | Requires external op amp for fourth channel; suitable only when one channel is unused or routed differently. | Select MAX4394EUD+T only if system design uses exactly three video paths and space/power constraints favor consolidation. |
| THS4052CD | Quad op amp with 210MHz bandwidth but no disable function; higher 12mA quiescent current per amp. | Lacks per-channel shutdown-unsuitable for power-gated multi-stream DVRs requiring <1mA standby per idle channel. | Choose THS4052CD only for ultra-wideband (>100MHz) applications where disable capability is unnecessary and thermal headroom permits higher IQ. |
Compared with MAX4394EUD+T and THS4052CD, the MAX4395EUD uniquely delivers four independently disableable amplifiers in a single 14-pin TSSOP, achieving optimal balance of video fidelity (0.015% DG), power efficiency (450µA/channel disabled), and integration density for multi-channel analog video systems.

FAQ
What supply voltage ranges does the MAX4395EUD support?
The MAX4395EUD operates from a single 4.5V to 11V supply or dual ±2.25V to ±5.5V supplies. Its input common-mode range extends to the negative rail (VEE), and outputs swing rail-to-rail under 75Ω load-making it compatible with both legacy 5V video systems and modern low-voltage embedded platforms. The MAX4395EUD maintains specified AC performance across this full range.
Does the MAX4395EUD include disable functionality for all four amplifiers?
Yes-the MAX4395EUD provides four independent disable inputs: DISABLEA, DISABLEB, DISABLEC, and DISABLED (pin 14 is DISABLEC; pin 1 is DISABLEA; pin 10 is DISABLEB; pin 14 is DISABLEC-note that MAX4395EUD has no DISABLED pin; it is a 4-channel part with DISABLEA/B/C/D mapped to pins 1, 10, 14, and N.C. per datasheet). Each disables its respective amplifier, reducing quiescent current to 450µA and setting output impedance to 95kΩ. This enables selective channel power-down in multi-stream video systems without affecting active channels.
What is the differential gain and phase error specification for the MAX4395EUD?
The MAX4395EUD delivers 0.015% differential gain error and 0.015° differential phase error under NTSC conditions with a 150Ω load-meeting broadcast-quality video standards. These values are measured at fC = 4.43MHz (NTSC color subcarrier) and confirm minimal hue/saturation distortion during analog video transmission, which is critical for surveillance and medical imaging applications where color accuracy affects diagnostic interpretation.
Can the MAX4395EUD drive a 75Ω coaxial cable directly?
Yes-the MAX4395EUD is explicitly characterized for 75Ω loads: it sources and sinks ±50mA while maintaining 0.015% differential gain error and 21ns settling time to 0.1%. Its output stage is optimized for back-terminated video lines, eliminating the need for external series resistors or buffer stages in standard CVBS applications. Layout best practices (short traces, ground plane, 0.1µF local bypass) are required to preserve this performance.
What package type is used for the MAX4395EUD?
The MAX4395EUD is supplied in a 14-pin TSSOP package (package code U14-1), measuring 5.0mm × 4.4mm × 1.2mm with 0.65mm pitch. It is RoHS-compliant and features an exposed pad for improved thermal dissipation-critical for sustained 50mA output drive in compact video modules. The pinout matches industry-standard TSSOP footprints, enabling drop-in compatibility with existing layouts designed for similar quad op amps.
