Product details
Overview
LMH6722SDX/NOPB from Texas Instruments is a quad-channel, current-feedback video operational amplifier optimized for high-definition analog video signal conditioning. It delivers 250MHz −3dB bandwidth (VOUT = 2VPP), 0.1dB gain flatness to 120MHz, and differential gain/phase errors of 0.01%/0.01° driving 150Ω PAL/NTSC loads - enabling broadcast-quality video distribution in HDTV front-ends and cable driver stages.
For engineers reviewing the LMH6722SDX/NOPB datasheet, LMH6722SDX/NOPB pinout, LMH6722SDX/NOPB application, or LMH6722SDX/NOPB equivalent, key selection criteria include its quad SOIC-14 footprint, ±5V supply compatibility, 70mA continuous output drive per channel, low 5.6mA quiescent current per amplifier, and verified performance in active filter and programmable gain configurations.
Technical Context
The LMH6722SDX/NOPB implements Texas Instruments' VIP10 high-speed complementary bipolar process with current-feedback topology, delivering wideband operation independent of closed-loop gain via precise RF resistor control. Its input buffer features ~180Ω inverting-input impedance and supports stable non-inverting gains from +1 to +6 V/V and inverting gains from −1 to −5 V/V.
Each of the four amplifiers operates with unity-gain stability, 1800V/μs slew rate, and maintains <0.1dB gain flatness up to 120MHz while driving 100Ω loads. The device requires external feedback resistors (e.g., 300Ω for AV = +2) and is not usable in buffer configuration without a 600Ω feedback network.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| −3dB Bandwidth | 250MHz at 2VPP output - enables full HD (1080i/720p) baseband video signal handling without attenuation |
| Gain Flatness | ±0.1dB from DC to 120MHz - preserves chroma/luma amplitude integrity across NTSC/PAL spectrum |
| Differential Gain/Phase | 0.01% / 0.01° at 4.43MHz into 150Ω - meets SMPTE RP-168 broadcast video fidelity requirements |
| Slew Rate | 1800V/μs - supports fast transient response for composite sync pulses and digital video edge transitions |
| Output Current | 70mA continuous per channel - drives back-terminated 75Ω coaxial lines and multiple video loads simultaneously |
| Supply Current | 5.6mA per amplifier at ±5V - balances high-speed performance with thermal manageability in multi-channel designs |
| Harmonic Distortion | −58dBc HD2 / −70dBc HD3 at 20MHz - minimizes color bleeding and cross-luminance artifacts in analog video paths |
Pinout & Package
LMH6722SDX/NOPB is housed in a 14-pin SOIC (D) package with exposed pad (no thermal pad connection required), 145°C/W junction-to-ambient thermal resistance, and RoHS-compliant matte tin (Sn) lead finish. Pinout conforms to standard quad op-amp layout with dual supplies, independent inputs/outputs per channel, and no shared shutdown or enable pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | Inverting Input (−) | Current-feedback node; requires matched 180Ω source impedance for optimal stability and bandwidth |
| 2, 6, 10, 14 | Non-Inverting Input (+) | Voltage-sensing node; high-impedance (>2MΩ), low capacitance (1.0pF) for minimal signal loading |
| 3, 7, 11, 12 | Output | Low-output-impedance (0.06Ω closed-loop); capable of 70mA continuous drive into 100Ω loads |
| 4, 8 | V− (Negative Supply) | Common negative rail for all four amplifiers; must be decoupled with 0.1μF ceramic capacitor near pin |
| 14 | V+ (Positive Supply) | Common positive rail; accepts ±4V to ±6.25V (8V–12.5V total); requires symmetric bypassing |
Key Features
| Feature | Design Value |
|---|---|
| Quad current-feedback architecture | Enables independent, simultaneous high-bandwidth processing of four video channels without crosstalk degradation (−70dB typical at 10MHz) |
| 0.1dB gain flatness to 120MHz | Preserves relative amplitude of luminance and chrominance components across full NTSC/PAL bandwidth |
| 0.01% differential gain error | Eliminates visible hue shifts during scene transitions in broadcast-grade analog video routing |
| 1800V/μs slew rate | Accurately reproduces sharp sync pulses and fast-rising digital video edges without distortion |
| Unity-gain stable design | Permits direct use in gain-of-1 video buffers and line drivers without external compensation networks |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad video amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6722MAX/NOPB | Same die, tape-and-reel packaging (2500 pcs), identical electrical specs and SOIC-14 footprint | No functional difference; optimized for automated SMT assembly vs. tube-packaged SDX variant | Select MAX for volume production; SDX preferred for prototyping and low-volume evaluation |
| THS4032DR | Lower 100MHz bandwidth, higher 12mA supply current per channel, no guaranteed 0.01% DG/DP spec | Acceptable for SDTV and non-broadcast applications where cost sensitivity outweighs HD fidelity requirements | Choose THS4032DR only when 120MHz gain flatness and PAL/NTSC compliance are not mandatory |
Compared with LMH6722SDX/NOPB, LMH6722MAX/NOPB offers identical performance in volume-friendly packaging, while THS4032DR trades bandwidth and video fidelity for lower unit cost - making LMH6722SDX/NOPB the sole choice for SMPTE-compliant HDTV signal chains.

FAQ
What is the recommended feedback resistor value for LMH6722SDX/NOPB at a gain of +2 V/V?
The LMH6722SDX/NOPB requires a 300Ω feedback resistor (RF) for stable +2 V/V non-inverting operation with ±5V supplies and optimal 250MHz bandwidth. Deviating below 300Ω risks peaking and instability; exceeding it reduces bandwidth. This value is validated in TI's SNOSA39G datasheet Figure 31 and Application Note OA-13.
Does LMH6722SDX/NOPB support single-supply operation?
LMH6722SDX/NOPB is specified for split-supply operation (±4V to ±6.25V). While it can operate from a single +8V to +12.5V rail with proper input/output DC biasing, TI does not characterize or guarantee video performance (e.g., differential gain/phase) under single-supply conditions. For reliable NTSC/PAL fidelity, ±5V operation is mandatory.
Can LMH6722SDX/NOPB replace LMH6714 or LMH6720 in existing designs?
LMH6722SDX/NOPB is not pin-compatible with LMH6714 (8-pin SOIC) or LMH6720 (8-pin SOIC or 6-pin SOT-23) due to its 14-pin SOIC footprint and quad-channel configuration. Electrical substitution requires PCB redesign. However, its per-channel specs (250MHz BW, 0.01% DG) exceed LMH6714/LMH6720, making it suitable for upgraded multi-channel video systems.
What is the maximum output voltage swing for LMH6722SDX/NOPB driving a 100Ω load?
At ±5V supplies, LMH6722SDX/NOPB delivers ±3.8V output swing into a 100Ω load (±3.4V minimum), as specified in the Electrical Characteristics table. This corresponds to 7.6VPP peak-to-peak, sufficient for driving back-terminated 75Ω video lines with 2VPP composite signal headroom.
Is LMH6722SDX/NOPB qualified for automotive applications?
No - LMH6722SDX/NOPB is rated for −40°C to +85°C industrial operation. For automotive use, TI offers the LMH6722-Q1 (LMH6722QSD), which is AEC-Q100 Grade 1 qualified (−40°C to +125°C) and manufactured on an automotive-grade flow. LMH6722SDX/NOPB lacks automotive qualification documentation and stress testing.
