Product details
Overview
LMH6611MKE/NOPB from Texas Instruments is a single-channel, rail-to-rail output voltage feedback operational amplifier with shutdown control, operating from 2.7 V to 11 V supply and delivering 345 MHz small-signal bandwidth, 460 V/µs slew rate, and ±100 mA linear output current at 5 V. It features 0.013 mV typical input offset voltage, 10 nV/√Hz input voltage noise, and is optimized for driving high-speed ADCs in video, test & measurement, and communications systems.
For engineers reviewing the LMH6611MKE/NOPB datasheet, LMH6611MKE/NOPB pinout, LMH6611MKE/NOPB application, or LMH6611MKE/NOPB equivalent, this page provides verified technical context, pin-level design meaning, real-world application mappings, and validated alternative options - all grounded in TI's official SNOSB00K datasheet (October 2013 revision) and package-specific characterization data.
Technical Context
The LMH6611MKE/NOPB uses a voltage-feedback architecture with precision-trimmed input stage enabling DC-critical performance: 103 dB open-loop gain and ±1.5 mV max input offset voltage over temperature. Its rail-to-rail output swings within 48 mV of either rail into 150 Ω at 5 V, supporting full-scale signal delivery to 10–14-bit ADCs without level-shifting.
Integrated active-low disable pin reduces quiescent current to 120 µA during shutdown, while turn-on/turn-off times of 20 ns and 60 ns enable fast power cycling in burst-mode systems. The device maintains stable operation across −40°C to +125°C and supports both single-supply (2.7–11 V) and split-supply (±1.35 V to ±5.5 V) configurations.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6609MF/NOPB | Lower bandwidth (170 MHz), no shutdown pin, SOT-23-5 package. | Lacks enable control; unsuitable for power-gated systems but lower cost for always-on video buffers. | Select when shutdown functionality is unnecessary and BOM cost reduction is prioritized over 345 MHz capability. |
| THS3201DGN | Current-feedback architecture, 1.8 GHz bandwidth, higher supply current (12.5 mA), SO-8 package. | Better for ultra-wideband (>500 MHz) applications but requires careful layout and lacks rail-to-rail output. | Choose only when >1 GHz small-signal bandwidth is required and output swing beyond 3.5 V is acceptable. |
Compared with LMH6611MKE/NOPB, LMH6609MF/NOPB trades bandwidth and shutdown for cost and simplicity, while THS3201DGN offers extreme speed at the expense of power, layout sensitivity, and output voltage range - making LMH6611MKE/NOPB the optimal balance for 100–500 MHz precision analog interfaces requiring rail-to-rail drive and low-power control.

FAQ
What is the maximum output current capability of the LMH6611MKE/NOPB?
The LMH6611MKE/NOPB delivers ±100 mA linear output current into a 150 Ω load at 5 V supply, as specified in the +5V Electrical Characteristics table. This allows direct driving of terminated video lines and ADC inputs without external buffering. Exceeding this current may cause thermal stress or distortion; continuous operation above ±70 mA is not recommended per datasheet guidance.
Does the LMH6611MKE/NOPB support single-supply operation?
Yes, the LMH6611MKE/NOPB operates from a single 2.7 V to 11 V supply, with input common-mode range extending 200 mV below the negative rail and output swinging rail-to-rail. At 5 V, its output reaches within 48 mV of ground and 76 mV of V+, enabling true single-supply use in ADC driver and video amplifier circuits without level-shifting components.
What is the function of the DISABLE pin on the LMH6611MKE/NOPB?
The DISABLE pin (Pin 6) is an active-low shutdown control that reduces quiescent supply current from 3.2 mA to 120 µA when pulled low. Its logic thresholds are 2.0 V (min high) and 1.0 V (max low) at 5 V supply. Turn-on and turn-off times are 20 ns and 60 ns respectively, enabling rapid power cycling in burst-mode applications like portable test gear or time-of-flight sensors.
How does the LMH6611MKE/NOPB compare to the dual-channel LMH6612 in terms of key specs?
The LMH6611MKE/NOPB and LMH6612 share identical AC/DC performance: same 345 MHz bandwidth, 460 V/µs slew rate, ±100 mA output, and 10 nV/√Hz noise. Key differences are channel count (single vs. dual), package (6-pin SOT-23 vs. 8-pin SOIC), and shutdown control (integrated on LMH6611MKE/NOPB only). Both operate across −40°C to +125°C and support identical supply ranges.
Is the LMH6611MKE/NOPB suitable for driving 1080i/720p analog video signals?
Yes, the LMH6611MKE/NOPB is explicitly listed in TI's datasheet for "1080i and 720p Analog Video Amplifier" applications. Its 45 MHz 0.1 dB bandwidth at AV = 2, <0.05% differential gain/phase, and ability to drive 2 VPP into 150 Ω meet SMPTE 253M/274M video line driver requirements. The rail-to-rail output ensures full-swing compliance with consumer video signal levels.
