Product details
Overview
MAX9502MEXK+ from Maxim Integrated is a +12dB fixed-gain, DC-coupled video amplifier with integrated 4th-order Chebyshev reconstruction filter, operating from 2.5V to 3.6V single supply and consuming only 5.3mA quiescent current. It drives 2VP-P into 150Ω, level-shifts sync tip to 110mV above ground, and supports portable video applications including digital still cameras and mobile phones.
For engineers reviewing the MAX9502MEXK+ datasheet, MAX9502MEXK+ pinout, MAX9502MEXK+ application, or MAX9502MEXK+ equivalent, this page delivers verified electrical parameters, SC70-5 pin mapping, shutdown timing (175ns disable), differential gain/phase error (0.4% / 0.4°), and real-world video signal integrity data for NTSC/PAL composite systems.
Technical Context
The MAX9502MEXK+ integrates a 4-pole Chebyshev lowpass filter with 5.5MHz passband flatness (±1dB), 3dB attenuation at 8MHz, and 55dB stopband rejection at 27MHz - optimized for NTSC/PAL composite video reconstruction. Its output stage provides fixed +12dB gain and internal short-circuit protection (95mA trip, pulsed 12μs off/0.8μs on).
DC-coupled input accepts 0–0.6V (at VCC = 3.0V) composite signals with 25mV max sync-tip voltage; output is DC-coupled and level-shifted to maintain linear operation across 150Ω loads. Shutdown logic is active-low with VIH ≥ 2.0V and VIL ≤ 0.65V over –40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain | +12dB fixed closed-loop gain - ensures consistent signal amplification without external feedback components. |
| Supply Voltage | 2.5V to 3.6V single supply - enables direct integration with low-voltage video DACs and battery-powered systems. |
| Quiescent Current | 5.3mA typical - minimizes power draw in always-on portable video paths. |
| Shutdown Current | 0.01μA - reduces system standby power to negligible levels during idle periods. |
| Sync-Tip Level | 110mV typical above ground - guarantees correct DC restoration and prevents clipping in 75Ω terminated video lines. |
| Differential Gain/Phase | 0.4% / 0.4° - meets broadcast-grade video fidelity requirements for NTSC composite signals. |
| Passband Flatness | ±1dB from 100kHz to 5.5MHz - preserves luminance/chrominance amplitude relationships across full video bandwidth. |
Pinout & Package
MAX9502MEXK+ uses the 5-pin SC70 package (1.6mm × 1.6mm × 0.95mm), optimized for space-constrained portable PCB layouts. Pin 1 is IN, Pin 2 is GND, Pin 3 is SHDN, Pin 4 is VCC, and Pin 5 is OUT - no internal connection on Pin 5 of μDFN variant, but Pin 5 is functional OUT in SC70.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Video Input | DC-coupled analog input accepting 0–0.6V composite video (sync tip ≤25mV); connects directly to current-output DAC. |
| 2 (GND) | Ground Reference | Primary return path for input, output, and supply; requires low-impedance PCB plane for video signal integrity. |
| 3 (SHDN) | Active-Low Shutdown Control | Drives device into 0.01μA sleep mode when pulled low; VIH ≥2.0V required for normal operation. |
| 4 (VCC) | Positive Power Supply | 2.5V–3.6V single supply input; must be bypassed with 0.1μF capacitor placed adjacent to pin. |
| 5 (OUT) | Video Output | DC-coupled output driving 2VP-P into 150Ω load; level-shifted to 110mV sync tip; requires 75Ω series back-termination. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 4th-order Chebyshev LPF | Eliminates need for external RC filters while delivering 55dB attenuation at 27MHz - critical for aliasing suppression in DAC output paths. |
| DC-coupled I/O architecture | Removes AC-coupling capacitors from signal path - avoids sync-tip distortion and simplifies layout in compact camera modules. |
| +12dB fixed gain | Matches low-output swing of modern video DACs without gain-setting resistors - reduces BOM count and layout sensitivity. |
| 110mV sync-tip level shift | Ensures proper DC restoration in downstream 75Ω-terminated video receivers - prevents black-level shift and contrast loss. |
| Active-low shutdown (175ns disable) | Enables rapid power gating in burst-mode video capture - cuts supply current to 0.01μA with minimal latency penalty. |
Applications
| Digital Still Cameras | Mobile Phones |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar video amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9502MELT+T | Same +12dB gain, same SC70/μDFN pinout family, but in 6-pin μDFN package (1mm × 1.5mm) and rated for –40°C to +85°C - identical electrical specs. | Requires different land pattern (μDFN vs SC70); same thermal and video performance; preferred where board space allows tighter footprint. | Select MAX9502MELT+T when μDFN placement is feasible and higher-density routing is needed; otherwise MAX9502MEXK+ remains optimal for SC70-compatible designs. |
| MAX9504AEUT+T | +12dB gain, SC70-6 package, includes optional DC offset bias control (not present in MAX9502MEXK+); wider input range (0–1.2V at 3V). | Supports variable sync-tip adjustment via external resistor; better suited for nonstandard DAC outputs or multi-standard video systems. | Choose MAX9504AEUT+T only if programmable DC offset is required; MAX9502MEXK+ offers lower cost and simpler layout where fixed 110mV sync-tip suffices. |
Compared with MAX9502MEXK+, MAX9502MELT+T offers identical video performance in a smaller μDFN package but demands PCB redesign, while MAX9504AEUT+T adds flexibility in DC offset tuning at the cost of increased complexity and component count - making MAX9502MEXK+ the optimal choice for cost-sensitive, space-constrained, fixed-offset composite video paths.

FAQ
What is the maximum input voltage range for MAX9502MEXK+ at 3.0V supply?
At VCC = 3.0V, the MAX9502MEXK+ accepts an input voltage range of 0V to 0.6V - specifically designed for composite video signals with sync tip ≤25mV. This range ensures linear operation of the +12dB amplifier stage and matches typical current-output DAC outputs. Exceeding 0.6V risks clipping or gain compression, as confirmed in the DC Electrical Characteristics table under "Input Voltage Range" for MAX9502M.
Does MAX9502MEXK+ require external AC-coupling capacitors on its input or output?
No, MAX9502MEXK+ does not require external AC-coupling capacitors - both input and output are DC-coupled per its architecture. The input directly accepts DC video signals from DACs, and the output is level-shifted to 110mV sync tip above ground to maintain linearity into 75Ω loads. Adding AC-coupling capacitors would distort sync-tip level and degrade low-frequency response, violating the design intent documented in the Applications Information section.
What is the typical disable time for MAX9502MEXK+ shutdown function?
The typical disable time (tOFF) for MAX9502MEXK+ is 175ns - defined as the time for the output to settle below 1% of final voltage after SHDN is pulled low. This value is measured with VIN = 0.5V and is specified in the AC Electrical Characteristics table. The fast disable supports burst-mode video capture and dynamic power management in portable systems without visible frame artifacts.
Can MAX9502MEXK+ drive a standard 75Ω video load directly?
MAX9502MEXK+ is specified to drive a 150Ω load to ground, not 75Ω directly. In standard 75Ω video systems, it connects through a 75Ω series back-termination resistor at the output, with the far end terminated in 75Ω - resulting in proper 75Ω source matching and 2VP-P delivered to the load. Driving 75Ω directly would halve output amplitude and risk instability, as confirmed by the Typical Operating Circuit and Output Considerations sections.
What is the stopband attenuation of MAX9502MEXK+ at 27MHz?
The stopband attenuation of MAX9502MEXK+ at 27MHz is 55dB (typical), as specified in both the General Description and AC Electrical Characteristics tables. This 4th-order Chebyshev filter performance ensures robust suppression of DAC image frequencies and high-frequency noise beyond the 5.5MHz video passband - critical for maintaining NTSC/PAL signal integrity and meeting FCC radiated emissions limits.
