Product details
Overview
LMH6722QSD/NOPB from Texas Instruments is a quad-channel, current-feedback video operational amplifier qualified to AEC-Q100 Grade 1 (−40°C to +125°C), delivering 250MHz −3dB bandwidth at 2VPP, 0.1dB gain flatness to 120MHz, and differential gain/phase of 0.01%/0.01° for NTSC/PAL video signals driving 75Ω back-terminated loads.
For engineers reviewing the LMH6722QSD/NOPB datasheet, LMH6722QSD/NOPB pinout, LMH6722QSD/NOPB application, or LMH6722QSD/NOPB equivalent, this page provides verified electrical parameters, automotive-grade thermal performance, quad-channel video signal integrity data, and validated alternatives for broadcast-quality video systems requiring high reliability in harsh environments.
Technical Context
The LMH6722QSD/NOPB implements Texas Instruments' VIP10 high-speed complementary bipolar process with current-feedback topology, enabling stable operation at gains from ±1V/V to ±6V/V while maintaining bandwidth independence from closed-loop gain via precise RF selection. Its input buffer features ~180Ω output impedance, dictating optimal feedback resistor values per gain configuration.
As a quad amplifier in SOIC-14 package, it supports simultaneous processing of multiple video channels-e.g., RGB+sync or Y/Cb/Cr-with matched AC performance across all four channels. It is unity-gain stable and optimized for ±5V supplies, with no internal shutdown function (unlike LMH6720).

FAQ
What is the maximum operating temperature for LMH6722QSD/NOPB?
The LMH6722QSD/NOPB is AEC-Q100 Grade 1 qualified, with a guaranteed operating junction temperature range of −40°C to +125°C. This specification is validated per automotive stress testing standards and applies across full electrical performance-no derating is required up to 125°C ambient when using appropriate PCB thermal design per SOIC-14 θJA = 145°C/W.
Does LMH6722QSD/NOPB include a shutdown pin?
No, LMH6722QSD/NOPB does not feature a shutdown pin. That functionality is exclusive to the LMH6720 variant. The LMH6722QSD/NOPB is a quad-channel video op amp with fixed operation-power must be cycled to disable. Its pinout contains no SD or enable terminal; all 14 pins are assigned to power, inputs, outputs, or NC functions as defined in Figure 5 of SNOSA39G.
What feedback resistor value is recommended for LMH6722QSD/NOPB at AV = +2V/V?
For non-inverting gain of +2V/V, TI specifies a 300Ω feedback resistor (RF) for LMH6722QSD/NOPB with ±5V supplies and 100Ω load. This value delivers near-maximal bandwidth (250MHz), optimal gain flatness (0.1dB to 120MHz), and stable step response-deviating significantly from 300Ω risks peaking, ringing, or oscillation due to current-feedback topology constraints.
Is LMH6722QSD/NOPB pin-compatible with LMH6722MA/NOPB?
Yes, LMH6722QSD/NOPB and LMH6722MA/NOPB are fully pin-compatible: both use identical SOIC-14 (Package D) footprints, identical pin assignments (per Figure 5), and share identical AEC-Q100 Grade 1 qualification and electrical specifications. The only distinction is packaging format-tube (QSD) vs. tube (MA)-making them direct drop-in replacements on PCBs.
What video standards does LMH6722QSD/NOPB support with specified differential gain/phase?
LMH6722QSD/NOPB is characterized for NTSC and PAL video standards, with differential gain and phase errors of 0.01% and 0.01° measured at 4.43MHz into 150Ω loads-meeting or exceeding ITU-R BT.470 and SMPTE RP 168 broadcast requirements. Performance remains valid for SECAM and HDTV baseband formats within its 250MHz bandwidth and 0.1dB flatness limit.
