Product details
Overview
The MAX9504BELT+ from Maxim Integrated is a ground-sensing, 6dB fixed-gain video amplifier optimized for DC-coupled composite video and luma (Y) signal amplification from current-output DACs. It delivers 45mA sourcing/40mA sinking output current, operates from +2.7V to +5.5V, features 160mV internal input offset to prevent sync-tip clipping, and supports dual 150Ω back-terminated loads in automotive video displays and portable media players.
For engineers reviewing the MAX9504BELT+ datasheet, MAX9504BELT+ pinout, MAX9504BELT+ application, or MAX9504BELT+ equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, confirmed application use cases, and two rigorously cross-checked alternative parts with documented functional and application-level differences.
Technical Context
The MAX9504BELT+ implements a high-output-current, single-supply op-amp architecture with integrated 160mV input offset voltage and unity-gain-stable feedback configuration (FB tied to OUT). Its rail-to-rail output stage maintains linearity down to GND when driving DC-coupled 150Ω loads, enabled by the offset shifting VIN into the linear input range.
It uses BiCMOS process technology to achieve 42MHz large-signal (-3dB) bandwidth and 165V/µs slew rate while consuming only 5mA quiescent current - critical for battery-powered video systems requiring NTSC/PAL signal fidelity, low differential gain/phase error (<0.1% / <0.3°), and sub-25ns settling time.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Fixed Voltage Gain | +2 V/V (+6dB) - sets precise signal scaling without external resistors; referenced to input offset for accurate DC-coupled video level translation. |
| Input Offset Voltage | 160mV (typ) - prevents sync-tip clipping on ground-referenced DAC outputs; enables full-swing DC-coupled operation without AC coupling. |
| Large-Signal Bandwidth | 42MHz (-3dB, 2VP-P) - supports full NTSC/PAL baseband video bandwidth (≤6MHz) with >6× margin for transient fidelity and multiburst response. |
| Output Current Drive | ±45mA (min sourcing), ±40mA (min sinking) - drives two parallel 150Ω back-terminated video loads (equivalent to one 75Ω load) without gain droop or distortion. |
| Shutdown Supply Current | 0.01µA (max) - reduces system power by >99.999% during display idle states; enables rapid wake-up (<300ns enable time) for responsive UI. |
| Supply Voltage Range | +2.7V to +5.5V - compatible with Li-ion (3.0–4.2V), 3.3V logic rails, and 5V legacy video subsystems without level-shifting. |
| Differential Gain/Phase | 0.1% / 0.3° (NTSC, VCC=3V) - meets broadcast-grade video fidelity requirements; ensures color accuracy and minimal hue shift across luminance levels. |
Pinout & Package
MAX9504BELT+ is housed in a lead-free 6-pin µDFN package (2mm × 2mm × 0.8mm, pkg code L622-1), optimized for space-constrained portable and automotive video modules. Thermal pad (exposed die attach) must be soldered to PCB ground for thermal stability and EMI control.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (FB) | Feedback Input | Internally connected to OUT; must be externally tied to OUT to configure unity-gain stable buffer mode per datasheet application circuit. |
| 2 (GND) | Analog Ground | Primary reference for input/output signals and internal biasing; requires low-impedance connection to PCB ground plane beneath thermal pad. |
| 3 (IN) | Video Input | High-impedance (4MΩ), DC-coupled node accepting current-DAC output (e.g., 0–1V luma); offset-shifted internally by 160mV before amplification. |
| 4 (VCC) | Positive Supply | Single supply input (2.7–5.5V); requires local 0.1µF ceramic bypass capacitor placed ≤2mm from pin to suppress high-frequency PSRR degradation. |
| 5 (SHDN) | Shutdown Control | Active-low digital input; pulled high (≥0.7×VCC) for normal operation; driven low (≤0.3×VCC) to enter 10nA shutdown state with 4kΩ high-Z output. |
| 6 (OUT) | Video Output | Low-impedance (2.5Ω typ @ 5MHz), rail-to-rail output capable of driving two 150Ω back-terminated loads simultaneously with <0.1% nonlinearity. |
Key Features
| Feature | Design Value |
|---|---|
| DC-Coupled Input/Output | Enables direct interface with current-output DACs and back-terminated coaxial video lines without AC coupling capacitors or level shifters. |
| Ground-Sensing Architecture with 160mV Offset | Guarantees linear operation for input signals down to 0V; eliminates sync-tip clipping in composite video and luma paths. |
| 42MHz Large-Signal Bandwidth | Preserves sharp edges and multiburst fidelity in standard-definition video; exceeds NTSC/PAL baseband requirement (6MHz) by 7×. |
| 45mA Output Sourcing Capability | Drives two 150Ω video loads (75Ω equivalent) simultaneously while maintaining <0.1dB gain flatness up to 10MHz. |
| 10nA Shutdown Current | Reduces standby power to nanowatt level in portable devices; enables fast wake-up (<300ns) without sacrificing video startup latency. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar video amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9504AEUT+ | No internal input offset (0mV VOS); otherwise identical pinout, bandwidth, and drive strength. | Designed for chroma (C) signals with blank level ≥500mV; unsuitable for ground-referenced luma/composite due to sync-tip clipping risk. | Select MAX9504AEUT+ only when amplifying chroma from current-DACs; avoid for luma or composite video paths. |
| LMH6732MF/NOPB | Higher supply current (12.5mA), no shutdown mode, no built-in offset; wider bandwidth (650MHz small-signal), but lower output drive (±35mA). | Requires external level-shifting for ground-referenced inputs; lacks integrated 160mV offset and 10nA shutdown - not drop-in for battery-powered designs. | Use LMH6732MF/NOPB only in AC-coupled, mains-powered systems needing ultra-wide bandwidth; not suitable for portable or automotive DC-coupled video. |
Compared with MAX9504BELT+, MAX9504AEUT+ offers identical performance except for missing the 160mV offset - making it chroma-only, while LMH6732MF/NOPB trades power efficiency and integrated offset for raw bandwidth, requiring redesign of biasing and power architecture.

FAQ
What is the primary function of the 160mV input offset in the MAX9504BELT+?
The 160mV input offset in the MAX9504BELT+ shifts ground-referenced video inputs (e.g., DAC luma output at 0V sync tip) into the linear input range of the amplifier. This prevents output clipping at the sync tip while maintaining full black-level fidelity - a critical feature for composite video and luma signal paths where the input signal swings down to 0V. Without this offset, the MAX9504BELT+ would distort the sync tip region.
Can the MAX9504BELT+ drive two 150Ω video loads simultaneously?
Yes, the MAX9504BELT+ is explicitly rated to drive two DC-coupled 150Ω back-terminated video loads simultaneously. Its ±45mA sourcing and ±40mA sinking output current capability allows it to handle the combined 75Ω equivalent load without gain compression or distortion. This dual-load drive is validated in the datasheet's Typical Application Circuit and used in Y/C-to-CVBS mixer designs.
What is the shutdown behavior of the MAX9504BELT+?
When SHDN is pulled low, the MAX9504BELT+ enters shutdown mode with supply current reduced to ≤1µA (typically 10nA). The output becomes high-impedance (4kΩ), and internal biasing is disabled. Wake-up occurs in ≤300ns after SHDN returns high, enabling rapid video activation in portable devices. This behavior is fully characterized across -40°C to +85°C.
How does the MAX9504BELT+ differ from the MAX9504AEUT+?
The MAX9504BELT+ and MAX9504AEUT+ share identical pinout, bandwidth, drive strength, and supply range - but differ critically in input offset: MAX9504BELT+ has 160mV (for luma/composite), while MAX9504AEUT+ has 0mV (for chroma). Using MAX9504AEUT+ on a luma signal risks sync-tip clipping; MAX9504BELT+ on chroma introduces unnecessary DC offset. They are functionally distinct variants, not interchangeable.
Is the MAX9504BELT+ suitable for NTSC and PAL video standards?
Yes, the MAX9504BELT+ meets NTSC and PAL requirements with differential gain <0.1% and differential phase <0.3°, 42MHz large-signal bandwidth (>6× baseband), and 25ns typical rise/fall times. Its 0.1% nonlinearity and 2ns group delay distortion ensure broadcast-grade color fidelity and timing accuracy - validated in the datasheet's Typical Operating Characteristics under NTSC test conditions.
