Product details
Overview
MAX11501USA+T from Maxim Integrated is a three-channel, 5th-order standard-definition video filter IC with transparent input clamps, +6dB output buffers, and flat passband response. It delivers 8.6MHz -3dB bandwidth, <0.1% differential gain error, and drives two 150Ω video loads per channel from a single +5V supply - used in set-top boxes and DVRs for anti-aliasing and DAC smoothing.
For engineers reviewing the MAX11501USA+T datasheet, MAX11501USA+T pinout, MAX11501USA+T application, or MAX11501USA+T equivalent, this page provides verified electrical parameters, SO-8 pin mapping, real-world video signal conditioning use cases, and validated alternative parts for SDTV signal chain design.
Technical Context
The MAX11501USA+T integrates three independent Butterworth 5th-order lowpass filters with precisely matched channel-to-channel gain (±0.02dB) and group delay (<10ns variation across 0–8MHz). Each channel includes a transparent clamp enabling direct DC-coupling from current-output DACs without external biasing.
Its output stage delivers +6dB gain (2× voltage), 280mV DC offset, and blanking-level control (<1V at 75Ω termination), supporting both AC- and DC-coupled outputs while maintaining NTSC-compliant differential phase (0.3°) and gain (0.1%) performance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| -3dB Bandwidth | 8.6MHz - ensures full passband coverage for 480i/576i video signals with minimal attenuation |
| Low-Frequency Gain | 6.0dB ±0.2dB - provides precise 2× voltage amplification with tight channel matching |
| Differential Gain Error | 0.1% - preserves color fidelity in composite/S-video applications |
| Differential Phase Error | 0.3° - maintains chrominance timing integrity for broadcast-quality SD video |
| Stopband Attenuation | -50dB at 27MHz - suppresses aliasing artifacts from DAC image frequencies |
| Supply Current | 26mA typical - enables low-power operation in multi-channel video systems |
| ESD Protection | 12kV HBM on outputs - safeguards against handling damage in manufacturing and field service |
Pinout & Package
MAX11501USA+T is housed in an 8-pin SO (Small Outline) package (package code S8+2), with exposed pad not electrically connected. The SO-8 footprint supports standard reflow assembly and thermal dissipation up to 470mW at +70°C ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN1 | Video Input Channel 1 | Accepts AC- or DC-coupled baseband video (Y/R/G/B/Pb/Pr); transparent clamp sets sync tip near GND when needed |
| 2 IN2 | Video Input Channel 2 | Independent input path identical to IN1; enables simultaneous RGB or Y/C processing |
| 3 IN3 | Video Input Channel 3 | Third parallel video channel; supports component video (e.g., YPbPr) or triple CVBS streams |
| 4 VCC | Positive Power Supply | +4.75V to +5.25V single supply; bypass with 0.1µF + 1.0µF capacitors adjacent to pin |
| 5 GND | Ground Reference | Analog ground return for all channels and internal bias networks; connect to low-impedance PCB plane |
| 6 OUT3 | Video Output Channel 3 | +6dB buffered output; drives 150Ω load (75Ω back-terminated) with <1V blanking level at termination |
| 7 OUT2 | Video Output Channel 2 | Matched output stage to OUT3; supports dual-load drive (2 × 75Ω) with thermal derating |
| 8 OUT1 | Video Output Channel 1 | Primary output with identical specs; pin 8 placement simplifies routing in SO-8 layout |
Key Features
| Feature | Design Value |
|---|---|
| Three-channel 5th-order Butterworth filter | Provides monotonic group delay and <5% overshoot in time domain for clean 2T/12.5T video response |
| Transparent input clamp | Enables direct interface to current-output DACs without external DC restoration circuitry |
| +6dB output buffer with 280mV offset | Generates standard 1.0Vpp–2.0Vpp video swing referenced to blanking level, eliminating AC-coupling caps |
| Flat passband response (MAX11501) | Delivers uniform gain across 0–8.6MHz - ideal for systems requiring no high-frequency compensation |
| 12kV HBM ESD protection on outputs | Eliminates need for external TVS diodes in front-end video routing, reducing BOM count |

Equivalent & Alternatives
The following parts are listed as comparable options for similar standard-definition video filtering applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX11502USA+T | +0.8dB peaking at 5MHz vs. flat response; same pinout, SO-8 package, and electrical specs except frequency shaping | Better compensates for system-level high-frequency roll-off in long-cable or multi-stage analog chains | Select MAX11502USA+T when driving >10ft coaxial cables or cascaded video stages where signal loss exceeds 1dB above 4MHz |
| AD8175ARZ | Triple 120MHz video op-amp with 0.1dB flatness to 10MHz; no integrated filter or clamp; requires external RC network for anti-aliasing | Higher bandwidth but lacks built-in 5th-order filtering and transparent clamping functionality | Choose AD8175ARZ only if custom filter tuning or >10MHz bandwidth is required; adds design complexity and BOM cost |
Compared with MAX11502USA+T, the MAX11501USA+T offers superior passband flatness for measurement-critical applications, while AD8175ARZ demands external components to replicate basic anti-aliasing - making MAX11501USA+T the optimal drop-in solution for cost-sensitive, space-constrained SD video designs.

FAQ
What is the exact -3dB bandwidth specification for MAX11501USA+T?
The MAX11501USA+T has a typical -3dB bandwidth of 8.6MHz, measured under standard conditions (VCC = +5V, RLOAD = 150Ω, TA = +25°C). This value is guaranteed across the full 0°C to +85°C operating range and ensures full passband coverage for 480i and 576i video standards without excessive attenuation.
Can MAX11501USA+T drive two 75Ω video loads simultaneously per channel?
Yes, the MAX11501USA+T output buffers are rated to drive two parallel 75Ω loads (equivalent to 150Ω total) per channel. Each output delivers 2VP-P into this load with <1V blanking level at the termination resistor. Thermal derating must be applied: junction temperature remains within limits at +70°C ambient when driving dual loads.
Does MAX11501USA+T require external DC restoration circuitry?
No. The MAX11501USA+T features transparent input clamps that automatically restore DC levels for AC-coupled video signals (e.g., SCART or unipolar Y/R/G/B), and accept DC-coupled DAC outputs directly. No external clamping diodes, resistors, or capacitors are needed for standard SD video interfacing.
What is the function of the 280mV DC offset in MAX11501USA+T output signals?
The MAX11501USA+T adds a fixed 280mV DC offset to all outputs, establishing the sync-tip reference level. Combined with +6dB gain, this produces a standard 1.0Vpp–2.0Vpp video swing (e.g., blanking at 0.28V, peak white at 2.28V), meeting EIA-770.1 and ITU-R BT.601 analog video interface requirements without external level-shifting.
How does MAX11501USA+T differ from MAX11502USA+T in practical design use?
The MAX11501USA+T provides flat passband response, while MAX11502USA+T adds +0.8dB peaking at 5MHz to compensate for system-level high-frequency losses. Both share identical pinout, SO-8 package, and electrical specs except frequency shaping - making them direct alternatives where passband shape is the sole differentiator.
