Product details
Overview
LMH6722MTX from Texas Instruments is a quad-channel, wideband current-feedback video operational amplifier in 14-pin SOIC package, delivering 250MHz −3dB bandwidth (VOUT = 2VPP), 1800V/μs slew rate, and 0.01% differential gain / 0.01° differential phase error for NTSC/PAL video signals driving 75Ω back-terminated loads. It serves as a high-fidelity analog front-end in broadcast-grade video distribution systems.
For engineers reviewing the LMH6722MTX datasheet, LMH6722MTX pinout, LMH6722MTX application, or LMH6722MTX equivalent, key selection criteria include its quad-channel layout, current-feedback architecture enabling stable gain-flat response to 120MHz, low 5.6mA per channel supply current, and compatibility with ±5V supplies in video switching, active filtering, and cable driver designs.
Technical Context
The LMH6722MTX employs TI's VIP10 high-speed complementary bipolar process with current-feedback topology-distinct from voltage-feedback op amps-enabling bandwidth independence from closed-loop gain when using appropriate feedback resistors (e.g., 300Ω for AV = +2). Its input buffer features ~180Ω inverting-input impedance and supports non-inverting gains from +1 to +6 V/V and inverting gains from −1 to −5 V/V.
It operates across −40°C to +85°C with ±4V to ±6.25V supply range, delivers 70mA continuous output current per channel, and maintains unity-gain stability. Unlike the LMH6720 (which includes TTL-compatible shutdown), the LMH6722MTX lacks a shutdown pin and is optimized for fixed-gain, multi-channel video signal conditioning where channel count and matching outweigh power gating needs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| −3dB Bandwidth | 250MHz at 2VPP output - enables full HD baseband video passband (up to ~120MHz) with margin |
| Slew Rate | 1800V/μs - supports fast transient response for composite sync pulses and digital video edges |
| Differential Gain / Phase | 0.01% / 0.01° at 4.43MHz - meets broadcast NTSC/PAL color fidelity requirements |
| Supply Current | 22.5mA typical (5.6mA per channel) - balances performance and thermal load in dense SOIC layouts |
| Output Current | 70mA continuous per channel - drives 75Ω back-terminated coaxial lines without external buffers |
| Gain Flatness | ±0.1dB to 120MHz - preserves amplitude integrity across entire video spectrum |
| Harmonic Distortion | −58dBc HD2 / −70dBc HD3 at 20MHz - minimizes color artifacts and cross-luminance interference |
Pinout & Package
LMH6722MTX is housed in a 14-pin SOIC (Package D), with exposed pad not present. Pin assignments follow standard quad op amp layout with independent inputs/outputs per channel and shared supply rails.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | Inverting Input (−) | Current-feedback node; requires matched 300Ω feedback resistor for AV = +2 configuration |
| 2, 6, 10, 14 | Non-Inverting Input (+) | High-impedance input (2MΩ); referenced to common-mode voltage range of ±2.2V |
| 3, 7, 11, 12 | Output | Low-output-impedance (0.06Ω closed-loop); capable of 70mA drive into 75Ω |
| 4 | V− (Negative Supply) | Accepts −5V (±5V operation); must be bypassed with 0.1μF ceramic capacitor near pin |
| 8 | V+ (Positive Supply) | Accepts +5V (±5V operation); requires local 0.1μF ceramic + bulk electrolytic bypassing |
| 12 | NC (No Connect) | Internally unused; must remain unconnected per datasheet guidance |
Key Features
| Feature | Design Value |
|---|---|
| Quad-channel integration | Four matched amplifiers in single SOIC-14 reduce board area and inter-channel skew vs. discrete singles |
| Current-feedback architecture | Enables flat frequency response up to 120MHz regardless of gain setting when RF is properly selected |
| Video-optimized linearity | 0.01% DG/0.01° DP ensures minimal color distortion in broadcast and professional video routing |
| 75Ω back-termination support | Output stage designed for direct 75Ω load driving-eliminates need for external series termination |
| Unity-gain stable | Operates reliably at AV = +1 without compensation; simplifies buffer and cable driver implementations |

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, identical electrical specs; differs only in tape-and-reel packaging (2500 pcs/reel vs. tube) | No functional difference; suited for automated SMT assembly instead of manual/hand-solder prototyping | Select LMH6722MAX/NOPB for volume production; LMH6722MTX for evaluation or low-volume builds |
| THS3202D | Single-channel, 1.8GHz GBW voltage-feedback op amp; higher power (12.5mA/ch), no DG/DP spec | Better for RF/IF gain stages than composite video; lacks broadcast video characterization and 75Ω drive optimization | Choose THS3202D only when >1GHz bandwidth is required and video fidelity metrics are secondary |
Compared with LMH6722MTX, LMH6722MAX/NOPB offers identical performance in automated manufacturing, while THS3202D trades video-specific linearity and 75Ω drive capability for raw bandwidth-making it unsuitable for NTSC/PAL signal chains but viable for wideband instrumentation where DG/DP is not specified.

FAQ
What is the maximum operating temperature range for the LMH6722MTX?
The LMH6722MTX is rated for operation from −40°C to +85°C ambient temperature, consistent with commercial-grade specifications. It does not carry automotive qualification (unlike the LMH6722-Q1 variant), and thermal design must account for its 145°C/W junction-to-ambient thermal resistance in SOIC packaging.
Does the LMH6722MTX include a shutdown pin like the LMH6720?
No, the LMH6722MTX does not feature a shutdown pin. That functionality is exclusive to the LMH6720 variant. The LMH6722MTX is a fixed-operation quad amplifier optimized for always-on video signal routing; power management must be handled externally if needed.
What feedback resistor value is recommended for non-inverting gain of +2V/V with the LMH6722MTX?
A 300Ω feedback resistor (RF) is specified in the LMH6722MTX datasheet for non-inverting gain of +2V/V with ±5V supplies. This value provides optimal bandwidth (250MHz), gain flatness (±0.1dB to 120MHz), and stability-deviating significantly from 300Ω risks peaking, roll-off, or oscillation.
Can the LMH6722MTX drive a 75Ω load directly without external series termination?
Yes, the LMH6722MTX is explicitly characterized to drive 75Ω back-terminated loads, delivering 70mA continuous output current per channel. Its output stage is optimized for this impedance, eliminating the need for external series resistors in standard video interface configurations.
Is the LMH6722MTX pin-compatible with other devices in the LMH67xx family?
No-LMH6722MTX (14-pin SOIC, quad) is not pin-compatible with LMH6714 (8-pin SOIC/SOT-23, single) or LMH6720 (8-pin SOIC/SOT-23, single with shutdown). Pinouts differ by channel count, supply pin placement, and presence/absence of shutdown logic; PCB layout must be specific to the LMH6722MTX's 14-pin SOIC footprint.
