Product details
Overview
LMH6722MAX from Texas Instruments is a quad-channel, unity-gain-stable, current-feedback video operational amplifier in 14-pin SOIC package. It delivers 250MHz −3dB bandwidth at 2VPP output, 0.1dB gain flatness to 120MHz, and differential gain/phase of 0.01%/0.01° for NTSC/PAL video signals driving 150Ω loads. It serves as a high-fidelity video buffer and distribution amplifier in broadcast-quality analog video systems.
For engineers reviewing the LMH6722MAX datasheet, LMH6722MAX pinout, LMH6722MAX application, or LMH6722MAX equivalent, key selection criteria include its quad-channel architecture, current-feedback topology enabling stable wideband operation across gains +1 to +6, low 5.6mA supply current per channel, and compatibility with back-terminated 75Ω/150Ω video loads without external compensation.
Technical Context
The LMH6722MAX uses Texas Instruments' VIP10 high-speed complementary bipolar process with current-feedback architecture, delivering fast settling (12ns to 0.05%), high slew rate (1800V/μs), and low distortion (−58dBc HD2, −70dBc HD3 at 20MHz). Its input stage features ~180Ω inverting-input impedance and supports ±5V supplies with common-mode range extending to ±VCC.
Unlike voltage-feedback op amps, the LMH6722MAX requires precise feedback resistor (RF) selection-typically 300Ω for AV = +2-to maintain bandwidth, gain flatness, and stability; deviations cause peaking or roll-off. It is optimized for non-inverting gains +1 to +6 and inverting gains −1 to −5, with performance degrading above ±7V/V due to low RG constraints.

Pinout & Package
LMH6722MAX is housed in a 14-pin SOIC (Package D) with exposed pad not present; thermal resistance θJA = 145°C/W. Pin numbering follows standard SOIC top-view convention (pin 1 = notch/left index).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Ch A) | Current-feedback node; requires matched RF/RG for gain setting; ~180Ω impedance |
| 2 | Non-Inverting Input (Ch A) | High-impedance voltage-sensing node; common-mode range ±2.2V |
| 3 | Output (Ch A) | Low-impedance (0.06Ω) driver capable of 70mA into 100Ω; supports back-termination |
| 4 | V− (Ch A & B) | Negative supply rail shared by channels A and B; must be decoupled locally |
| 5 | Non-Inverting Input (Ch B) | Independent high-Z input for second channel; identical specs to Ch A |
| 6 | Inverting Input (Ch B) | Current-feedback node for Ch B; separate RF/RG required per channel |
| 7 | Output (Ch B) | Independent output; no crosstalk specification given but measured <−40dBc at 100MHz |
| 8 | NC | No internal connection; leave unconnected or ground for noise immunity |
| 9 | Output (Ch C) | Third independent output; same drive capability and bandwidth as Ch A/B |
| 10 | Inverting Input (Ch C) | Current-feedback node for Ch C; requires dedicated feedback network |
| 11 | Non-Inverting Input (Ch C) | High-Z input for Ch C; identical electrical behavior to other non-inverting inputs |
| 12 | V+ (Ch C & D) | Positive supply rail shared by channels C and D; decouple with 0.1μF ceramic + bulk cap |
| 13 | Inverting Input (Ch D) | Current-feedback node for fourth channel; fully independent of other channels |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel wideband video amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6722MA/NOPB | Same die, 14-pin SOIC tube packaging (55 pcs); identical electrical specs and pinout | No difference in circuit design or layout; differs only in packaging format and reel/tube orientation | Select LMH6722MA/NOPB for low-volume prototyping or manual assembly where tape-and-reel handling is unnecessary |
| LMH6722-Q1 | Automotive-grade variant qualified to AEC-Q100 Grade 1 (−40°C to +125°C); otherwise identical AC/DC specs | Validated for under-hood or infotainment video systems requiring extended temperature operation and automotive PPAP compliance | Choose LMH6722-Q1 only when automotive qualification and extended temperature range are mandatory; not drop-in for commercial designs |
Compared with LMH6722MA/NOPB, the LMH6722MAX offers tape-and-reel delivery for automated SMT placement, while LMH6722-Q1 adds automotive qualification at higher cost and longer lead time-neither provides electrical improvement over the base LMH6722MAX.

FAQ
What is the recommended feedback resistor value for LMH6722MAX at AV = +2?
The LMH6722MAX requires a 300Ω feedback resistor (RF) for optimal performance at non-inverting gain +2V/V with ±5V supplies. This value balances bandwidth (250MHz), gain flatness (0.1dB to 120MHz), and stability. Using 147Ω causes peaking; 400Ω improves stability but reduces bandwidth. The LMH6722MAX datasheet explicitly specifies RF = 300Ω for all typical performance plots and electrical characteristics tables.
Does LMH6722MAX support single-supply operation?
The LMH6722MAX is specified for split-supply operation (±4V to ±6.25V) and does not support true single-supply use. Its input common-mode range extends to ±VCC, but the output swing is asymmetric (±3.4V into 100Ω) and lacks rail-to-rail capability. For single-ended video signals, level-shifting circuitry or a negative bias rail is required-TI does not characterize or guarantee performance with VEE = 0V.
How does LMH6722MAX differ from LMH6720 in pinout and functionality?
The LMH6722MAX is a quad-channel device in 14-pin SOIC with pins 1–7 and 9–14 assigned to four independent amplifiers; the LMH6720 is a single-channel amplifier with shutdown pin (pin 6 in 6-pin SOT-23 or pin 8 in 8-pin SOIC). They share no pin compatibility-LMH6722MAX has no shutdown function, and its pinout is incompatible with LMH6720's single-channel layout or control interface.
Can LMH6722MAX drive a 75Ω back-terminated coaxial cable directly?
Yes-the LMH6722MAX is characterized driving 150Ω loads (equivalent to two 75Ω terminations in parallel) with 0.01% differential gain error. Its 70mA output current and 0.06Ω closed-loop output resistance allow direct connection to a single 75Ω back-terminated line with minimal signal reflection or amplitude loss, provided the feedback network is configured for unity or moderate gain.
What is the thermal resistance and maximum power dissipation for LMH6722MAX?
The LMH6722MAX in 14-pin SOIC (Package D) has θJA = 145°C/W. At ±5V supplies and 5.6mA per channel (22.4mA total), quiescent power is 112mW. With 70mA output into 100Ω, additional dissipation depends on signal swing; maximum allowable power is calculated as PMAX = (150°C − TA)/145°C/W. At 25°C ambient, PMAX ≈ 0.869W-well above typical operating dissipation of the LMH6722MAX.
