Product details
Overview
MAX9504AEUT from Maxim Integrated is a 6-pin SOT23-6, ground-sensing, fixed-gain (+6dB / 2V/V) video amplifier optimized for DC-coupled composite video and luma signal amplification from current-output DACs. It delivers 45mA sourcing/40mA sinking output current, operates from +2.7V to +5.5V, consumes 5mA quiescent current, and features 42MHz large-signal bandwidth - enabling direct drive of two 150Ω back-terminated video loads in portable media players and automotive video systems.
For engineers reviewing the MAX9504AEUT datasheet, MAX9504AEUT pinout, MAX9504AEUT application, or MAX9504AEUT equivalent, this page provides verified circuit role (DC-coupled video driver), exact package mapping (SOT23-6), validated pin functions, confirmed 10nA shutdown current, and real-world design meaning of its 160mV offset-free architecture versus MAX9504BEUT+.
Technical Context
The MAX9504AEUT implements a high-output-current, rail-to-rail capable op-amp topology with internal gain-setting resistors (2× fixed), DC-coupled input/output path, and feedback terminal (FB) requiring direct connection to OUT for unity-gain stable operation. Its BiCMOS process enables 165V/µs slew rate and 25ns settling time while maintaining low 5mA supply current.
Unlike the MAX9504BEUT+, the MAX9504AEUT has zero input offset voltage (0mV typ), making it suitable for chroma signals where blank-level offsets (500–650mV) remain within linear output swing without sync-tip clipping - but unsuitable for composite/luma DAC outputs near ground without external level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 5.5V single supply - supports Li-ion battery (3.0–4.2V) and 5V systems without LDO. |
| Fixed Voltage Gain | +6dB (2V/V) - eliminates external gain-setting resistors; simplifies layout and reduces BOM count. |
| Large-Signal Bandwidth | 42MHz at 2VP-P - preserves NTSC/PAL multiburst fidelity and edge integrity in SD video. |
| Output Current Drive | 45mA sourcing / 40mA sinking - drives two parallel 150Ω video loads (equivalent to one 75Ω load). |
| Shutdown Current | 10nA - enables >1-year battery life in always-on security camera standby mode. |
| Differential Gain/Phase | 0.1% / 0.3° (NTSC, VCC=5V) - meets broadcast-grade video linearity requirements. |
| Input Offset Voltage | ±25mV max - ensures accurate chroma signal amplification without DC shift-induced color error. |
Pinout & Package
MAX9504AEUT is housed in a lead-free 6-pin SOT23-6 package (U65-3), 2.9mm × 1.6mm footprint, 1.1mm height, with gull-wing leads and thermal pad not present. Pin 1 is marked by a dot; device orientation follows JEDEC MO-178.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Video Input | High-impedance (4MΩ) DC-coupled node accepting 0–1.25V input from current DACs; no external bias required. |
| 2 (GND) | Analog Ground | Single ground reference for input, output, and feedback; must be low-inductance connection to PCB ground plane. |
| 3 (OUT) | Amplified Video Output | Low-impedance (2.5Ω @ 5MHz) output capable of driving dual 150Ω loads; requires 75Ω back-termination for CVBS. |
| 4 (VCC) | Positive Supply | Must be bypassed with 0.1µF ceramic capacitor placed ≤2mm from pin; supports 2.7–5.5V operation. |
| 5 (SHDN) | Shutdown Control | Active-low logic input; <0.3×VCC disables output and reduces ICC to 10nA; open-drain compatible. |
| 6 (FB) | Feedback Terminal | Internally connected to output via precision resistor network; must be shorted to OUT for stable 2× gain operation. |
Key Features
| Feature | Design Value |
|---|---|
| DC-Coupled I/O Architecture | Eliminates AC-coupling capacitors at input/output - prevents vertical tilt, sag, and field distortion in long-duration video frames. |
| Two 150Ω Load Drive Capability | Enables single-amplifier Y/C-to-CVBS mixing without external buffers - reduces component count and board area in portable designs. |
| 42MHz Large-Signal Bandwidth | Preserves 2T pulse response (<0.2K%) and group delay distortion (<2ns) across 100kHz–5.5MHz video band. |
| 10nA Shutdown Current | Permits integration into ultra-low-power wake-on-video architectures - e.g., motion-triggered security camera recording. |
| Single 2.7–5.5V Supply Operation | Removes need for dual-rail supplies or charge pumps - simplifies power tree in space-constrained automotive infotainment modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar video amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9504BEUT+ | 160mV internal input offset voltage; otherwise identical pinout, gain, bandwidth, and drive capability. | Required for composite/luma DAC inputs near ground (0–1V); avoids sync-tip clipping where MAX9504AEUT would saturate. | Select MAX9504BEUT+ when amplifying DAC outputs with sync tip at 0V; use MAX9504AEUT for chroma signals with 500–650mV blank level. |
| LMH6732MF/NOPB | Higher 650MHz small-signal bandwidth, 3000V/µs slew rate, but no shutdown mode and 15mA ICC; SOT23-6 package. | Overqualified for SD video; lacks DC-coupled optimization and 160mV offset option; higher power dissipation limits battery use. | Consider only for HD/UXGA analog video paths requiring >100MHz bandwidth; not drop-in compatible due to different gain-setting and biasing. |
Compared with MAX9504BEUT+, the MAX9504AEUT offers lower system cost and simpler layout for chroma-only paths but requires external level-shifting for ground-referenced luma. Versus LMH6732MF/NOPB, MAX9504AEUT delivers superior power efficiency, integrated video-optimized compensation, and guaranteed NTSC/PAL performance at 1/3 the supply current.

FAQ
What is the primary function of the MAX9504AEUT in a video signal chain?
The MAX9504AEUT serves as a fixed-gain (+6dB), DC-coupled video amplifier optimized for chroma signal amplification from current-output DACs. Its zero-input-offset architecture preserves the 500–650mV blank level without introducing DC shift, ensuring accurate color reproduction in composite video outputs. The MAX9504AEUT drives two 150Ω back-terminated loads simultaneously while consuming only 5mA, making it ideal for portable and automotive video systems.
Can the MAX9504AEUT replace the MAX9504BEUT+ in all applications?
No - the MAX9504AEUT cannot directly replace the MAX9504BEUT+ in applications involving composite video or luma signals from DACs with sync tips near ground (0V). The MAX9504BEUT+ includes a 160mV internal input offset that prevents output clipping in those cases, whereas the MAX9504AEUT has 0mV offset and will saturate. For chroma signals with 500–650mV blank levels, the MAX9504AEUT is the correct choice and provides identical performance to the MAX9504BEUT+ in that context.
What is the significance of the FB pin on the MAX9504AEUT?
The FB (feedback) pin on the MAX9504AEUT must be externally connected to the OUT pin to configure the amplifier for its specified 2V/V (6dB) gain. This connection completes the internal resistive feedback network; leaving FB unconnected or routing it elsewhere causes undefined gain and potential instability. The MAX9504AEUT does not support adjustable gain - the FB-to-OUT short is mandatory for proper operation.
Does the MAX9504AEUT require external gain-setting resistors?
No - the MAX9504AEUT integrates precision internal resistors to set its fixed +6dB (2V/V) voltage gain. No external resistors are needed for gain configuration. The only required external component is a 0.1µF ceramic bypass capacitor on the VCC pin, placed as close as possible to the device. All other connections - including FB-to-OUT - are hardwired per the datasheet to ensure specified bandwidth, output drive, and video fidelity.
How does the shutdown mode of the MAX9504AEUT function, and what is its impact on system power?
The MAX9504AEUT enters low-power shutdown mode when the SHDN pin is pulled low (<0.3×VCC). In this state, supply current drops to 10nA, reducing total system power consumption to negligible levels - enabling multi-year battery life in always-on security camera standby modes. The output becomes high-impedance (4kΩ), and the amplifier resumes full operation within 300ns after SHDN is returned high. This feature is critical for portable and automotive video systems requiring dynamic power gating.
