Analog Devices Inc. ADA4417-3ARMZ-R7

Overview

ADA4417-3ARMZ-R7 from Analog Devices is a triple-channel, sixth-order Butterworth video reconstruction filter IC optimized for high-definition Y/Pb/Pr and Y/G/B video signal conditioning. It delivers −1 dB bandwidth of 38 MHz, 44 dB out-of-band rejection at 75 MHz, and 5 ns group delay variation across 1–36 MHz - enabling accurate HD video passband fidelity in set-top boxes and HDTVs.

For engineers reviewing the ADA4417-3ARMZ-R7 datasheet, ADA4417-3ARMZ-R7 pinout, ADA4417-3ARMZ-R7 application, or ADA4417-3ARMZ-R7 equivalent, key selection criteria include its rail-to-rail output drive into dual 75 Ω loads, pin-selectable 200 mV DC output offset, single-supply operation (3.3 V to 5 V), and disable mode reducing quiescent current to 10 μA.

Technical Context

The ADA4417-3ARMZ-R7 integrates three identical, fully independent sixth-order Butterworth low-pass filters with group-delay equalization - each configured for fixed ×2 voltage gain and optimized for 1080i/1080p video bandwidths. Its input stage accepts dc-coupled, ground-referenced video signals and adds a 100 mV input-referred DC offset to prevent sync-tip clipping.

Each channel features rail-to-rail output buffers capable of sourcing/sinking 30 mA (at 5 V) and driving two 75 Ω terminated loads simultaneously. The DISABLE pin enables active-low power-down, while the DCO pin selects between 200 mV output offset (DCO = VCC) or zero offset (DCO = GND), both referenced to input level.

FAQ

What is the function of the DCO pin on the ADA4417-3ARMZ-R7?

The DCO (DC Offset) pin on the ADA4417-3ARMZ-R7 selects output DC level behavior: tying DCO to VCC applies a 200 mV input-referred DC offset to all three outputs, preventing sync-tip clipping in ac-coupled 75 Ω systems; tying DCO to GND disables offset, allowing output DC level to track input. This eliminates external level-shifting components in legacy video designs.

Can the ADA4417-3ARMZ-R7 drive two 75 Ω loads simultaneously per channel?

Yes, the ADA4417-3ARMZ-R7 output buffers are rated for 30 mA linear current per channel at 5 V and can directly drive two parallel 75 Ω terminated loads (equivalent to 37.5 Ω) either ac- or dc-coupled. For ac-coupled dual loads, use either two 220 µF capacitors or one 470 µF common capacitor per output, as validated in Analog Devices' Figure 26 and Figure 27.

What is the minimum supply voltage for the ADA4417-3ARMZ-R7 to maintain full video performance?

The ADA4417-3ARMZ-R7 operates down to 3.3 V while retaining full specification compliance: −1 dB bandwidth remains 38 MHz, differential gain stays ≤0.07 %, and group delay variation holds at 4 ns (1–36 MHz). At 3.3 V, output swing is 0.08 V to 3.05 V, supporting 2 V_p-p video with rail-to-rail capability - essential for low-voltage portable HD devices.

How does the DISABLE pin affect power consumption in the ADA4417-3ARMZ-R7?

Asserting the DISABLE pin (pulling low) reduces the ADA4417-3ARMZ-R7's quiescent current from 22.5 mA (typical, DCO = 0, 5 V) to just 10 μA - a 2250× reduction. Deassertion time is 2.0 μs (5 V), enabling rapid reactivation for burst-mode video switching. Input-to-output isolation exceeds 92 dB when disabled, blocking signal leakage during sleep states.

Is the ADA4417-3ARMZ-R7 pin-compatible with other members of the ADA4417 family?

Yes, all variants of the ADA4417-3 - including ADA4417-3ARMZ, ADA4417-3ARMZ-R7, and ADA4417-3ARMZ-RL - share identical 10-lead MSOP (RM-10) pinout, electrical specifications, and thermal characteristics. The suffix differences (-R7, -RL) denote reel quantity (1,000 vs. 2,500 units) and packaging; no functional or layout changes exist between them.
