Product details

Overview

ADA4411-3ARQZ from Analog Devices is a triple-channel, sixth-order video filter and buffer IC designed for RGB, YPbPr, and YUV signal conditioning in HD/SD video systems. It delivers selectable cutoff frequencies (9/18/36 MHz), ×2 or ×4 gain per channel, rail-to-rail 4.5 V_p-p output swing on +5 V supply, and integrated 2:1 input multiplexers - enabling flexible source switching in set-top boxes and HDTVs.

For engineers reviewing the ADA4411-3ARQZ datasheet, ADA4411-3ARQZ pinout, ADA4411-3ARQZ application, or ADA4411-3ARQZ equivalent, key selection criteria include its −1 dB bandwidth (30.5 MHz at 36 MHz cutoff), input-referred ±500 mV DC offset adjust, 24-lead QSOP package with dual ground planes, and disable current of 15 μA - all critical for power-sensitive, multi-standard video reconstruction designs.

Technical Context

The ADA4411-3ARQZ integrates three independent sixth-order Butterworth filters with group-delay-optimized response, each supporting three discrete cutoff frequencies selected via dual logic pins (F_SEL_A/F_SEL_B). Its input stage features high-impedance, dc-coupled 2:1 multiplexers with level-shifting circuitry to accommodate ground-referenced video sources in single-supply operation.

Each channel includes programmable gain (×2/×4 via G_SEL), differential DC offset control (LEVEL1/LEVEL2), and rail-to-rail output buffers capable of driving two 75 Ω doubly terminated loads. The device operates from +4.5 V to ±5 V, with PSRR > 62 dB and quiescent current of 56 mA (enabled) or 15 μA (disabled).

Key Specifications

−1 dB Bandwidth	30.5 MHz at 36 MHz cutoff - ensures full signal fidelity for 720p/1080i timing without attenuation in critical baseband region
Output Swing	4.5 V_p-p on +5 V supply - meets SMPTE/ITU-R BT.601 amplitude requirements for dc-coupled video distribution
DC Offset Adjust Range	±500 mV input-referred - enables precise blanking-level placement in single-supply systems without external clamping
Crosstalk	−62 dB at 5 MHz - prevents color bleeding between Y/G, Pb/B, and Pr/R channels in component video routing
Input MUX Isolation	91 dB at 1 MHz - maintains signal integrity when switching between dual video sources per channel
Disable Current	15 μA typical - reduces system standby power by >99% versus active mode (56 mA), critical for always-on media devices
Supply Range	+4.5 V to ±5 V - supports both cost-sensitive single-supply consumer gear and high-fidelity dual-supply professional equipment

Pinout & Package

ADA4411-3ARQZ is housed in a 24-lead QSOP (Quad Small Outline Package), 0.154" wide body, with exposed pad not electrically connected. Pin layout separates analog signal paths (Y1/G1, Pb1/B1, Pr1/R1, Y2/G2, Pb2/B2, Pr2/R2) from digital controls (F_SEL_A, F_SEL_B, G_SEL, MUX, DISABLE) and dedicated ground planes (GND, DGND, VEE).

Pin/Terminal	Circuit Role	Design Meaning
1, 24	LEVEL1 / LEVEL2	Differential DC offset control inputs - output voltage shift = (LEVEL1 − LEVEL2) × gain; sets blanking level in single-supply video systems
2	DISABLE	Active-high shutdown control - pulls to VCC to reduce supply current to 15 μA; also serves as logic reference for other control pins
3, 10, 14	Y1/G1 / Y2/G2 / Pr2/R2	Multiplexed video inputs - each pair (e.g., Y1/Y2) shares one 2:1 mux; supports dual-source RGB/YPbPr switching per channel
5, 12	Pb1/B1 / Pb2/B2	Chroma blue-difference inputs - high-impedance, dc-coupled; no internal termination required
7, 14	Pr1/R1 / Pr2/R2	Chroma red-difference inputs - identical electrical specs to Pb/B inputs; enables full component video signal path replication
8, 9	F_SEL_A / F_SEL_B	Cutoff frequency select bits - binary encoding selects 9/18/36 MHz per channel; matches NTSC/PAL/HD standards
15	MUX	Multiplexer select line - chooses between Channel 1 (Y1/G1, Pb1/B1, Pr1/R1) and Channel 2 (Y2/G2, Pb2/B2, Pr2/R2) inputs
16, 22	VCC	Positive supply pins - must be decoupled locally with 0.1 μF ceramic capacitors; supports +4.5 V to +12 V operation
17, 19, 21	Pr/R_OUT / Pb/B_OUT / Y/G_OUT	Rail-to-rail video outputs - drive two 75 Ω loads simultaneously; 4.5 V_p-p swing on +5 V supply satisfies broadcast-level amplitude
18, 20	VEE	Negative supply pins - required for dual-supply operation (±5 V); enables negative-going sync tip excursions below ground
23	G_SEL	Gain select input - logic high = ×2 gain, low = ×4 gain; configures output amplitude for different DAC output levels or cable loss

Key Features

Feature	Design Value

Equivalent & Alternatives

The following parts are listed as comparable options for similar video filter and buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
LMH0387SQ/NOPB	Single-channel SDI reclocker with integrated equalizer; no multiplexer, no DC offset control, no selectable cutoff	Designed for serial digital video (SDI) transport, not analog component video reconstruction	Use only for digital video signal regeneration - not a functional substitute for ADA4411-3ARQZ's analog filtering and buffering role
THS7353IPWPR	Triple-channel SD video filter with fixed 10 MHz cutoff; no HD bandwidth, no gain select, no disable mode	Limited to standard-definition (NTSC/PAL) signals; lacks 36 MHz capability for 720p/1080i support	Acceptable for legacy SD-only designs but cannot replace ADA4411-3ARQZ in HD-capable products requiring resolution flexibility

Compared with LMH0387SQ/NOPB and THS7353IPWPR, ADA4411-3ARQZ uniquely combines HD-ready bandwidth selection, per-channel multiplexing, and ultra-low-power disable - making it the only option for cost-optimized, multi-standard analog video output stages in modern consumer AV equipment.

FAQ

What video standards does the ADA4411-3ARQZ support?

The ADA4411-3ARQZ supports RGB, YPbPr, YUV, SD (NTSC/PAL), and HD (720p/1080i) video standards through its selectable 9/18/36 MHz cutoff frequencies. Each channel independently configures bandwidth to match signal bandwidth requirements - for example, 36 MHz for RGB computer graphics, 18 MHz for 720p, and 9 MHz for NTSC composite-derived YPbPr. This eliminates need for multiple discrete filter designs in multi-format devices.

How does the ADA4411-3ARQZ handle DC level shifting in single-supply operation?

The ADA4411-3ARQZ uses differential LEVEL1/LEVEL2 inputs to apply input-referred DC offset up to ±500 mV, allowing precise blanking-level positioning without external clamping circuits. In single-supply (+5 V) use, setting LEVEL1 = 300 mV and LEVEL2 = 0 V yields +600 mV output offset - lifting sync tips safely above ground and preventing negative-rail clipping. This feature is integral to the ADA4411-3ARQZ architecture and requires no additional components.

Can the ADA4411-3ARQZ drive two 75 Ω loads simultaneously?

Yes, each output of the ADA4411-3ARQZ (Y/G_OUT, Pb/B_OUT, Pr/R_OUT) can drive two 75 Ω doubly terminated loads - either ac-coupled (using ≥220 μF capacitors) or dc-coupled. The output buffers deliver 30 mA linear current per channel and maintain −1 dB bandwidth within ±2.5% of spec even under 150 Ω effective load. This capability is verified in the ADA4411-3ARQZ datasheet Table 1 and enables direct connection to dual-display or distribution amplifier outputs.

What is the purpose of the DISABLE pin on the ADA4411-3ARQZ?

The DISABLE pin on the ADA4411-3ARQZ is an active-high shutdown control that reduces quiescent current from 56 mA to 15 μA when pulled to VCC. It also serves as the logic reference voltage for F_SEL_A, F_SEL_B, G_SEL, and MUX pins - meaning these inputs must be referenced to DISABLE potential, not ground, when the device is enabled. This dual function simplifies level translation in mixed-voltage systems and is a defined operational requirement of the ADA4411-3ARQZ.

Does the ADA4411-3ARQZ require external passive components for basic operation?

No, the ADA4411-3ARQZ requires only local 0.1 μF ceramic decoupling capacitors on VCC and VEE pins, plus 0.1 μF bypass caps on LEVEL1/LEVEL2 inputs - all specified in the ADA4411-3ARQZ datasheet Figure 21. Its sixth-order filters, gain control, and DC offset adjustment are fully integrated; no external resistors, capacitors, or inductors are needed for cutoff frequency selection, gain setting, or level shifting - reducing bill-of-materials and layout complexity.
