Product details
Overview
LMH6612MAX/NOPB from Texas Instruments is a dual-channel, rail-to-rail output, high-speed voltage feedback amplifier optimized for single-supply operation (2.7 V to 11 V). It delivers 345 MHz small-signal bandwidth, 460 V/µs slew rate, and 0.1% settling in 67 ns at 5 V supply - enabling precision ADC driving, video signal conditioning, and active filter applications in space-constrained industrial and test equipment.
For engineers reviewing the LMH6612MAX/NOPB datasheet, LMH6612MAX/NOPB pinout, LMH6612MAX/NOPB application, or LMH6612MAX/NOPB equivalent, this page provides verified package mapping (SOIC-8), confirmed DC/AC performance across temperature (−40°C to +125°C), real-world output swing data into 150 Ω, and validated alternatives for ADC driver and video buffer use cases.
Technical Context
The LMH6612MAX/NOPB employs a voltage-feedback architecture with trimmed input offset voltage (±1.5 mV max) and high open-loop gain (103 dB), supporting DC-critical closed-loop configurations such as low-pass filtering in I/Q baseband paths. Its rail-to-rail output stage delivers ±100 mA linear output current and swings within 49 mV of ground on 5 V supply with 1 kΩ load.
Designed for power-conscious systems, it draws only 3.7 mA per channel at 5 V while maintaining 102 dBc SFDR at 100 kHz (AV = 2, 2 VPP), 45 MHz 0.1 dB bandwidth into 150 Ω, and −40°C to +125°C extended industrial temperature operation - meeting requirements for HDTV analog video (1080i/720p) and high-speed sensor signal chains.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS3202D | Higher slew rate (3000 V/µs), wider bandwidth (1.8 GHz), but higher supply current (12.5 mA/channel) and no rail-to-rail output. | Better suited for RF IF gain stages requiring extreme speed; unsuitable for rail-to-rail DC-coupled ADC drivers. | Select THS3202D only when >1 GHz bandwidth and >1000 V/µs slew are mandatory; LMH6612MAX/NOPB remains optimal for cost-sensitive, power-aware video and data acquisition. |
| OPA2835IDR | Lower quiescent current (1.8 mA/channel), rail-to-rail I/O, but reduced bandwidth (35 MHz) and slower settling (120 ns). | Targeted at portable instrumentation and low-power sensor interfaces where speed is secondary to battery life. | Choose OPA2835IDR for sub-50 MHz applications with strict <2 mA/channel limits; LMH6612MAX/NOPB is preferred when 345 MHz BW and 67 ns settling are required. |
Compared with THS3202D and OPA2835IDR, LMH6612MAX/NOPB uniquely balances 345 MHz bandwidth, rail-to-rail output, 67 ns settling, and 3.7 mA/channel consumption - making it the most suitable choice for high-resolution ADC drivers and HDTV video buffers where both speed and single-supply simplicity are essential.

FAQ
What is the maximum operating supply voltage for LMH6612MAX/NOPB?
The LMH6612MAX/NOPB supports a total supply voltage range of 2.7 V to 11 V for single-supply operation, or ±1.35 V to ±5.5 V for split-supply configurations. Absolute maximum supply voltage is 12 V (V+ − V−), beyond which permanent damage may occur. Operation at 11 V is fully specified across the −40°C to +125°C temperature range.
Does LMH6612MAX/NOPB support rail-to-rail input common-mode voltage?
No, LMH6612MAX/NOPB does not feature rail-to-rail input. Its input common-mode voltage range (CMVR) is specified as −0.2 V to 3.8 V at 5 V supply - extending 200 mV below the negative rail and up to 1.2 V below the positive rail. This allows ground-referenced inputs in single-supply systems but requires biasing for full-rail input capture.
Can LMH6612MAX/NOPB drive a 75 Ω video load directly?
LMH6612MAX/NOPB is characterized for 150 Ω and 1 kΩ loads, with guaranteed output swing and distortion performance into those impedances. While it can source ±100 mA, direct 75 Ω termination is not tested or specified. For 75 Ω video applications, a series resistor (e.g., 75 Ω) or dedicated video driver like the THS7374 is recommended to ensure compliance with SMPTE standards and maintain signal integrity.
What is the typical input offset voltage drift over temperature for LMH6612MAX/NOPB?
The LMH6612MAX/NOPB has a typical input offset voltage average drift of 4 µV/°C, as specified in the Electrical Characteristics table. This low drift ensures stable DC performance across its full −40°C to +125°C operating range, critical for precision applications such as current sensing and programmable gain amplifiers where baseline error must remain predictable.
Is LMH6612MAX/NOPB pin-compatible with LMH6611?
No, LMH6612MAX/NOPB is not pin-compatible with LMH6611. The LMH6611 is a single-channel amplifier in 6-pin SOT-23 packaging with a dedicated shutdown pin, while LMH6612MAX/NOPB is a dual-channel device in 8-pin SOIC packaging with no shutdown functionality. Their pinouts, channel count, and package footprints are fundamentally different - PCB layout changes are required for substitution.
