Product details
Overview
MAX4395ESD+ from Analog Devices is a quad-channel, rail-to-rail output, high-speed voltage-feedback op amp with disable functionality, delivering 85MHz -3dB bandwidth, 500V/μs slew rate, and 0.015% differential gain error. It operates from single 4.5V–11V or dual ±2.25V–±5.5V supplies and targets video line driving in surveillance systems and set-top boxes.
For engineers reviewing the MAX4395ESD+ datasheet, MAX4395ESD+ pinout, MAX4395ESD+ application, or MAX4395ESD+ equivalent, key selection criteria include quad-channel integration with per-amplifier disable, 75Ω video load drive capability, low distortion at 5MHz (-59dBc SFDR), and SO-14 package compatibility with industrial temperature range (-40°C to +85°C).
Technical Context
The MAX4395ESD+ employs BiCMOS process technology and combines voltage-feedback architecture with current-feedback techniques to achieve high slew rate and wide bandwidth while maintaining stability in unity-gain configurations. Its input stage supports common-mode voltage down to VEE and within 2.25V of VCC, enabling robust operation in single-supply video signal chains.
Each of its four amplifiers features independent disable control (DISABLEA–DISABLED), placing outputs in high-impedance state (≥40kΩ) with only 450μA quiescent current per channel. Output drive capability reaches ±50mA into 75Ω loads, supporting NTSC-compliant video transmission with 0.015° differential phase error.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4394ESD+ | Triple-channel version with identical specs and SO-14 package; lacks fourth amplifier and DISABLED pin | Used where only three video channels are needed; saves board space vs. using two duals | Select MAX4394ESD+ when system requires exactly three independent video drivers |
| THS4032DR | TI dual op amp in SO-8; 100MHz bandwidth but no disable function; higher 15mA quiescent current per amp | Requires external enable logic and additional decoupling; less suitable for power-gated multi-channel systems | Choose THS4032DR only if higher bandwidth outweighs disable requirement and power budget allows |
Compared with MAX4394ESD+, MAX4395ESD+ adds a fourth amplifier and per-channel disable for Amplifier C (pin 14), enabling full quad-channel power management; versus THS4032DR, it offers lower power, integrated disable, and superior video fidelity specs but in a larger SO-14 footprint.

FAQ
What is the operating temperature range for the MAX4395ESD+?
The MAX4395ESD+ is specified for operation from -40°C to +85°C ambient temperature. This industrial temperature range ensures reliable performance in surveillance enclosures, set-top boxes, and industrial data acquisition environments where ambient conditions exceed commercial limits. The device's thermal resistance (θJA = 120°C/W on single-layer board) supports sustained operation within this range when properly heatsinked or mounted on multilayer PCBs.
Does the MAX4395ESD+ support single-supply operation?
Yes, the MAX4395ESD+ supports true single-supply operation from 4.5V to 11V. Its input common-mode range extends to the negative rail (VEE, typically ground), and outputs swing rail-to-rail-within 200mV of both supply rails under 75Ω load. This enables direct interfacing with 5V or 3.3V microcontrollers and ADCs without level-shifting circuitry, simplifying design in cost-sensitive video endpoint applications.
How does the disable function work on the MAX4395ESD+?
The MAX4395ESD+ provides independent disable control for Amplifiers A, B, and C via pins 4 (DISABLEA), 10 (DISABLEB), and 14 (DISABLEC); Amplifier D has no dedicated disable pin. When a DISABLE pin is pulled low, the corresponding output enters high-impedance state (≥40kΩ) while quiescent current drops to 450μA per enabled amplifier. This allows dynamic channel gating in multi-input video switchers without affecting other active channels.
Can the MAX4395ESD+ drive a 75Ω coaxial video load directly?
Yes, the MAX4395ESD+ is explicitly characterized to drive 75Ω video loads with ±50mA output current capability. It maintains 0.015% differential gain and 0.015° differential phase error under these conditions-meeting NTSC broadcast standards. The SO-14 package's layout-compatible pinout allows direct connection to 75Ω traces or BNC/RCA connectors without external series resistors or termination networks.
What is the small-signal -3dB bandwidth of the MAX4395ESD+?
The MAX4395ESD+ delivers a small-signal -3dB bandwidth of 85MHz at VOUT = 100mVP-P, as tested under standard conditions (VCC = 5V, VEE = -5V, RL = ∞ to GND). This bandwidth supports full baseband video spectrum (up to ~5.5MHz for NTSC) with ample margin, ensuring flat gain response and minimal group delay across the entire signal band without requiring external peaking compensation.
