Product details
Overview
MAX4090AAXT+ from Maxim Integrated is a 3V/5V, 6dB video buffer IC with integrated sync-tip clamp and low-power shutdown mode, designed for DC-coupled 150Ω back-terminated video loads in portable systems. It delivers 2V/V voltage gain, 45MHz large-signal -3dB bandwidth, 275V/µs slew rate, and operates from 2.7V to 5.5V supply while consuming only 6.5mA quiescent current. It is used in automotive-grade portable video applications requiring extended temperature operation.
For engineers reviewing the MAX4090AAXT+ datasheet, MAX4090AAXT+ pinout, MAX4090AAXT+ application, or MAX4090AAXT+ equivalent, key selection criteria include its -40°C to +125°C automotive temperature rating, 150nA shutdown current, input clamp voltage of 0.38V (typ), differential gain/phase performance (0.5%/0.5° at 5V), and SC70-6 package compatibility with space-constrained video signal chains.
Technical Context
The MAX4090AAXT+ implements an active sync-tip clamp circuit that fixes the video waveform's minimum to ~0.38V at both input and output, enabling true DC-coupled operation without external level-shifting. Its feedback configuration (FB tied to OUT) establishes unity-gain stable buffering with fixed 6dB (2×) voltage gain referenced to the clamp voltage.
It features rail-to-rail capable output drive into 150Ω loads (2.55V high swing at 3V supply), 2.5Ω typical output impedance at 5MHz, and robust power-supply rejection (>60dB up to 100kHz). Shutdown control is TTL/CMOS-compatible with VIL = 0.3×VCC and VIH = 0.7×VCC thresholds, enabling seamless integration into battery-powered video subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 5.5V - supports direct connection to common Li-ion battery rails (3.0V–3.6V) and 5V logic domains without regulation. |
| Quiescent Supply Current | 6.5mA (typ) - enables low static power draw in always-on video signal paths. |
| Shutdown Supply Current | 150nA - reduces system standby power by >43,000×, critical for battery longevity in portable devices. |
| Voltage Gain | 2.0V/V (typ) - provides precise 6dB amplification referenced to clamp voltage, preserving video signal integrity across black-to-white transitions. |
| Large-Signal -3dB Bandwidth | 45MHz - fully supports NTSC/PAL composite video (≤6MHz baseband) with ample margin for harmonics and reconstruction filter roll-off. |
| Differential Gain / Phase | 0.5% / 0.5° (at 5V) - meets broadcast-quality video fidelity requirements for color accuracy and timing stability. |
| Input Clamp Voltage | 0.38V (typ) - sets baseline sync-tip level for DC-coupled video, eliminating need for AC-coupling capacitors at output stage. |
| Slew Rate | 275V/µs - ensures minimal distortion on fast video edges (e.g., multiburst test patterns) without overshoot or ringing. |
Pinout & Package
MAX4090AAXT+ is housed in a RoHS-compliant 6-pin SC70 package (package code X6SN-1), measuring 2.0mm × 1.25mm × 0.9mm, optimized for high-density portable PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Video output driver - delivers amplified, clamped video signal to 150Ω back-terminated load; rail-to-rail capable. |
| 2 | GND | Analog ground reference - must be connected to low-impedance system ground plane to minimize noise coupling into video path. |
| 3 | IN | AC-coupled video input - accepts sync-tip clamped signal; requires 0.1µF input capacitor for proper clamp operation. |
| 4 | VCC | Positive supply - bypass with 0.1µF ceramic capacitor placed <1mm from pin to suppress high-frequency supply noise. |
| 5 | SHDN | Active-high shutdown control - logic-low disables output and reduces ICC to 150nA; compatible with 3V/5V GPIOs. |
| 6 | FB | Unity-gain feedback - internally connected to OUT; must be externally shorted to OUT for standard 6dB buffer configuration. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar video buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4090EUT-T | Same architecture and pinout, but rated for -40°C to +85°C industrial range; 6.5mA ICC and 150nA ISHDN identical. | Not qualified for automotive under-hood or dashboard environments requiring +125°C operation. | Select MAX4090EUT-T only for cost-sensitive industrial/portable designs where extended temperature is unnecessary. |
| LMH6732MF/NOPB | Wider bandwidth (220MHz), higher supply current (12.5mA), no integrated sync-tip clamp; SOT23-6 package. | Requires external clamping circuitry and additional passive components to replicate MAX4090AAXT+'s DC-coupled functionality. | Choose LMH6732MF/NOPB only when >100MHz bandwidth is mandatory and system-level clamp design resources are available. |
Compared with MAX4090EUT-T, the MAX4090AAXT+ adds automotive temperature qualification without sacrificing power or performance; compared with LMH6732MF/NOPB, it integrates critical video-specific functions (clamp, DC-coupling, low-IQ shutdown) into a single, smaller, lower-risk solution.

FAQ
What is the maximum operating temperature specification for MAX4090AAXT+?
The MAX4090AAXT+ is specified for operation from -40°C to +125°C, making it suitable for automotive under-hood and dashboard-mounted video interface applications where ambient temperatures exceed standard industrial limits. This rating is confirmed in the Ordering Information table and Absolute Maximum Ratings section of the official datasheet.
Does MAX4090AAXT+ require external components to implement sync-tip clamping?
No, MAX4090AAXT+ integrates a precision active sync-tip clamp circuit. It requires only a 0.1µF input coupling capacitor (X7R ceramic recommended) to store the clamp voltage; no external resistors, diodes, or op-amps are needed to establish the 0.38V (typ) clamp level at the output.
Can MAX4090AAXT+ drive a 75Ω video load?
MAX4090AAXT+ is optimized for 150Ω back-terminated loads per its Electrical Characteristics and Typical Application Circuit. Driving a 75Ω load may cause excessive current draw (up to 85mA sourcing/sinking), increased thermal stress, and potential degradation of differential gain/phase specs; use only with verified 150Ω termination.
What is the function of the FB pin on MAX4090AAXT+?
The FB pin on MAX4090AAXT+ is the unity-gain feedback terminal. It must be externally shorted to the OUT pin to configure the device as a stable 6dB (2×) video buffer. Leaving FB unconnected or connecting it elsewhere invalidates the gain and stability specifications defined in the datasheet.
Is MAX4090AAXT+ pin-compatible with other MAX4090 variants like MAX4090EUT-T?
Yes, MAX4090AAXT+ is pin-compatible with all MAX4090 variants in the same package type-in this case, the SC70-6 footprint. The MAX4090AAXT+ shares identical pinout, electrical behavior, and layout requirements with MAX4090EXT-T and MAX4090EUT-T, differing only in temperature grade and top-mark (ACW vs. ABM/ABOX).
