Product details
Overview
LMH6658MMX/NOPB from Texas Instruments is a dual, single-supply, voltage-feedback operational amplifier with 270-MHz −3dB bandwidth (AV = +1), 700 V/µs slew rate, and 140-MHz gain-bandwidth product. It operates from 3 V to 12 V, delivers ±80/−90 mA output current, and supports rail-to-rail input down to 0.5 V beyond V−-enabling low-level signal amplification in portable video and ADC buffer applications.
For engineers reviewing the LMH6658MMX/NOPB datasheet, LMH6658MMX/NOPB pinout, LMH6658MMX/NOPB application, or LMH6658MMX/NOPB equivalent, key selection criteria include its 0.03% differential gain / 0.10° differential phase performance for NTSC video, 37 ns 0.1% settling time, and VSSOP-8 package compatibility with space-constrained industrial and communications designs.
Technical Context
The LMH6658MMX/NOPB employs a voltage-feedback architecture optimized for high-speed large-signal operation, supporting stable unity-gain and AV = +2 configurations with ≤1.5 dB peaking up to 100 MHz. Its input stage extends below V− by 0.5 V and remains functional within 1.7 V of V+, enabling ground-referenced signal conditioning without level-shifting circuitry.
Output drive capability includes 80 mA sourcing and 90 mA sinking into 100 Ω loads, with 0.8 V from rails swing at 2 kΩ and full-power bandwidth of 55 MHz (−1 dB, 3 VPP, AV = −1). Cross-talk rejection is 69 dB at 5 MHz, confirming channel isolation suitable for dual-channel video or sensor signal paths.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6658MAX/NOPB | VSSOP-8 package with same electrical specs; differs only in tape-and-reel packaging (3,000 pcs/reel vs 2,500 pcs/reel for MMX) | Identical functional use; selected for automated SMT line compatibility with different reel size requirements | Choose LMH6658MAX/NOPB when standard 3k-reel logistics are required; no design or layout impact. |
| THS3202DGNR | Higher slew rate (3,000 V/µs), wider bandwidth (1.8 GHz), but higher supply current (12.5 mA/amp) and no V−-below-rail input | Better suited for RF IF gain stages than video or low-level DC-coupled sensing | Select THS3202DGNR only when >1 GHz bandwidth is mandatory and single-supply ground-sensing is not required. |
Compared with LMH6658MAX/NOPB, LMH6658MMX/NOPB offers identical performance in a 2.5k-reel format ideal for prototyping and low-volume production; versus THS3202DGNR, it trades raw speed for lower power, rail-to-rail input, and cost efficiency in video and portable instrumentation.

FAQ
What is the maximum operating supply voltage for LMH6658MMX/NOPB?
The LMH6658MMX/NOPB supports a supply voltage range of 3 V to 12 V on a single supply (V+ to V−). Absolute maximum ratings specify 12.6 V differential supply; operation above 12 V risks permanent damage. At 12 V, thermal limits require careful PCB layout with copper pour under the exposed pad to maintain junction temperature below 150°C.
Does LMH6658MMX/NOPB support true rail-to-rail input?
LMH6658MMX/NOPB provides rail-to-rail input capability extending 0.5 V below V− and within 1.7 V of V+, confirmed in both 5 V and ±5 V operating conditions. This allows direct amplification of signals referenced to system ground without external level-shifting circuitry-critical for low-side current sensing and single-supply sensor interfaces.
What is the typical output current capability of LMH6658MMX/NOPB?
LMH6658MMX/NOPB delivers +80 mA sourcing and −90 mA sinking into 100 Ω loads at room temperature, with output swing limited to 0.8 V from either rail at 2 kΩ. Output short-circuit current is rated at 100–220 mA depending on load configuration, and the device includes momentary short-circuit protection per TI's test methodology.
Can LMH6658MMX/NOPB be used in NTSC video applications?
Yes, LMH6658MMX/NOPB is explicitly characterized for NTSC video: differential gain is 0.03% and differential phase is 0.10°, meeting broadcast-grade requirements. Its 270 MHz bandwidth, low 1.5 dB peaking up to 100 MHz, and 69 dB crosstalk rejection make it suitable for composite video line driving and Y/C separation circuits in portable DVD and monitor designs.
What is the thermal resistance (RθJA) of LMH6658MMX/NOPB in VSSOP-8 package?
The LMH6658MMX/NOPB in VSSOP-8 (DGK) package has a junction-to-ambient thermal resistance (RθJA) of 235°C/W, as specified in TI's SNOSA35G datasheet Section 6.4. This value assumes standard JEDEC 2-layer board conditions; adding thermal vias under the exposed pad can reduce effective RθJA by up to 30% in production layouts.
