Product details
Overview
LMH6722SD/NOPB from Texas Instruments is a quad-channel, current-feedback video operational amplifier optimized for broadcast-quality NTSC/PAL signal conditioning. It delivers 250MHz −3dB bandwidth (VOUT = 2VPP), 0.1dB gain flatness to 120MHz, differential gain/phase of 0.01%/0.01°, and 1800V/μs slew rate while consuming 22.5mA per channel from ±5V supplies. It is used in high-density video distribution systems driving 75Ω back-terminated coaxial lines.
For engineers reviewing the LMH6722SD/NOPB datasheet, LMH6722SD/NOPB pinout, LMH6722SD/NOPB application, or LMH6722SD/NOPB equivalent, key selection criteria include its quad SOIC-14 package, current-feedback architecture enabling stable wideband gain control, low distortion (−58dBc HD2 / −70dBc HD3 at 20MHz), and suitability for multi-channel video switching, active filtering, and HDTV signal routing where channel-to-channel crosstalk and timing skew must be minimized.
Technical Context
The LMH6722SD/NOPB implements a current-feedback topology with a high-impedance input buffer and low-impedance output stage, enabling bandwidth independence from closed-loop gain when RF is properly selected (e.g., 300Ω for AV = +2). Its VIP10 bipolar process ensures low input bias current (±12µA typical) and high output drive capability (70mA continuous).
Unlike voltage-feedback op amps, it requires careful feedback resistor selection to avoid peaking or instability-recommended RF values range from 200Ω to 400Ω depending on gain configuration. It is unity-gain stable and supports non-inverting gains from +1 to +6V/V and inverting gains from −1 to −5V/V without compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| −3dB Bandwidth | 250MHz at 2VPP output - enables full HD baseband video signal amplification without attenuation |
| Gain Flatness | 0.1dB to 120MHz - preserves chroma/luma amplitude integrity across NTSC/PAL spectrum |
| Differential Gain/Phase | 0.01% / 0.01° at 4.43MHz - meets broadcast-grade video fidelity requirements for composite signals |
| Slew Rate | 1800V/μs - supports fast transient response for sharp video edges and sync pulses |
| Supply Current | 22.5mA per channel (typical) - balances performance and thermal load in quad-channel designs |
| Output Current | 70mA continuous - drives 75Ω back-terminated video loads without clipping |
| Harmonic Distortion | −58dBc HD2 / −70dBc HD3 at 20MHz - minimizes color artifacts and ghosting in analog video paths |
Pinout & Package
LMH6722SD/NOPB is housed in a 14-pin SOIC (Package D) with exposed pad thermal enhancement. Pin numbering follows standard SOIC top-view convention; device operates with dual ±5V supplies and features four independent amplifier channels sharing common power rails.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | Output | Amplified output for Channels A, B, C, D respectively; low-impedance source capable of 70mA drive |
| 2, 6, 10, 14 | Inverting Input (−) | Current-summing node for feedback network; requires precise RF selection (e.g., 300Ω for AV=+2) |
| 3, 7, 11, 12 | Non-Inverting Input (+) | High-impedance input (2MΩ) with 1pF capacitance; sensitive to layout-induced parasitics |
| 4, 8 | V− (Negative Supply) | Common negative rail connection for all four amplifiers; must be low-inductance and bypassed |
| 12 | V+ (Positive Supply) | Common positive rail connection; shared by all channels; requires local 0.1µF ceramic bypass |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar wideband 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; intended for automated SMT assembly rather than prototyping | Select LMH6722MAX/NOPB for volume production; LMH6722SD/NOPB is tube-packaged for evaluation and low-volume builds |
| LMH6722QSD/NOPB | AEC-Q100 Grade 1 qualified (−40°C to +125°C), automotive-grade flow; otherwise identical AC/DC specs | Qualified for under-hood automotive video systems (e.g., surround-view cameras); not required for industrial/commercial use | Choose LMH6722QSD/NOPB only if automotive qualification and extended temperature operation are mandatory |
Compared with LMH6722SD/NOPB, LMH6722MAX/NOPB offers identical performance in high-volume manufacturing format, while LMH6722QSD/NOPB adds automotive qualification at no AC performance trade-off-making the original LMH6722SD/NOPB optimal for cost-sensitive commercial video infrastructure where extended temp range is unnecessary.

FAQ
What is the recommended feedback resistor value for LMH6722SD/NOPB at a gain of +2V/V?
The recommended feedback resistor (RF) for LMH6722SD/NOPB at AV = +2V/V is 300Ω, as specified in the Electrical Characteristics table and validated in Figure 31 of the SNOSA39G datasheet. This value provides near-maximal bandwidth (250MHz), excellent gain flatness (0.1dB to 120MHz), and stable operation without peaking or oscillation. Deviating significantly below 300Ω risks overshoot and instability; increasing RF reduces bandwidth but improves phase margin.
Does LMH6722SD/NOPB support single-supply operation?
LMH6722SD/NOPB is characterized and optimized for dual-supply operation (±4V to ±6.25V), and its input common-mode range extends to ±VCC. While it can operate from a single +8V to +12.5V supply with appropriate DC biasing, TI does not specify performance parameters under single-supply conditions in the SNOSA39G datasheet. For guaranteed specifications-including differential gain/phase, bandwidth, and distortion-the device must be used with symmetric dual supplies such as ±5V.
How does LMH6722SD/NOPB differ from LMH6720 in terms of functionality?
LMH6722SD/NOPB is a quad-channel current-feedback op amp with no shutdown function, whereas LMH6720 is a single-channel version featuring a TTL-compatible shutdown pin (SD) with 11ns turn-on and 7ns turn-off times. LMH6722SD/NOPB delivers higher per-channel supply current (22.5mA vs. 8mA for LMH6720) and is optimized for multi-channel video routing, while LMH6720 targets low-power portable or multiplexed applications where dynamic power gating is required.
What is the maximum output voltage swing for LMH6722SD/NOPB into a 100Ω load?
At ±5V supplies, LMH6722SD/NOPB delivers a minimum output voltage swing of ±3.6V into a 100Ω load, as specified in the Electrical Characteristics table under "VOUT Output Voltage Range". This corresponds to 7.2VPP linear swing, sufficient to drive 75Ω back-terminated video lines to standard 1VPP levels with ample headroom for sync tips and burst amplitudes without clipping.
Is LMH6722SD/NOPB pin-compatible with other devices in the LMH67xx family?
No-LMH6722SD/NOPB is not pin-compatible with LMH6714 (single, 5-pin SOT-23), LMH6720 (single, 6-pin SOT-23 or 8-pin SOIC), or LMH6722 variants in TSSOP or WSON packages. Its 14-pin SOIC (D) footprint is unique to the quad-channel configuration. Pin mapping differs fundamentally: LMH6722SD/NOPB allocates pins 1/5/9/13 as outputs and shares V+/V− across all channels, unlike the single-channel layouts which dedicate pins to individual supply and shutdown functions.
