Product details
Overview
LMH6612MA/NOPB from Texas Instruments is a dual-channel, rail-to-rail output voltage feedback amplifier optimized for high-speed, low-power single-supply systems. It delivers 345 MHz small-signal bandwidth, 460 V/µs slew rate, and ±100 mA linear output current at 5V supply, with precision-trimmed input offset voltage (±1.5 mV max) and 10 nV/√Hz input voltage noise - enabling high-fidelity ADC driving in 10–14-bit data acquisition systems.
For engineers reviewing the LMH6612MA/NOPB datasheet, LMH6612MA/NOPB pinout, LMH6612MA/NOPB application, or LMH6612MA/NOPB equivalent, this page provides verified electrical specifications, SOIC-8 terminal mapping, real-world video and sensor interface use cases, and validated alternative options for design flexibility and supply continuity.
Technical Context
The LMH6612MA/NOPB operates on 2.7V to 11V single supply or ±1.35V to ±5.5V split supply, supporting rail-to-rail output swing within 49 mV of ground on 5V with 150Ω load. Its voltage-feedback architecture achieves 103 dB open-loop gain and 81–98 dB CMRR across −40°C to +125°C, with input common-mode range extending from −0.2 V to 3.8 V (vs. 0 V rail) at 5V supply.
Designed for DC-sensitive high-speed applications, it features 100 ns 0.01% settling time, 45 MHz 0.1 dB bandwidth at AV = 2 into 150Ω, and >102 dBc SFDR at 100 kHz - meeting requirements for baseband I/Q filtering, HDTV analog video amplification (1080i/720p), and precision current sensing with fast transient response.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small Signal Bandwidth | 345 MHz at AV = +1, RL = 1 kΩ - supports wideband signal conditioning up to UHF frequencies. |
| Slew Rate | 460 V/µs - enables clean 2 VPP step response without slewing distortion in high-speed DAC buffers. |
| Supply Current per Channel | 3.7 mA typical at 5V - balances performance and power efficiency in portable or thermally constrained designs. |
| Input Offset Voltage | ±1.5 mV max at 25°C - ensures <0.015% gain error in precision gain stages and active filters. |
| Output Current Drive | ±100 mA linear - drives 150Ω video loads or 1 kΩ ADC inputs without external buffering. |
| 0.1 dB Bandwidth | 45 MHz at AV = 2, 2 VPP into 150Ω - meets flatness requirements for 720p/1080i analog video transmission. |
| Settling Time (0.01%) | 100 ns - satisfies timing budgets for 10–14-bit ADC sampling at ≥10 MSPS. |
Pinout & Package
LMH6612MA/NOPB is housed in an 8-pin SOIC (SOIC-8) package with standard JEDEC MS-012AC footprint (5.3 mm × 6.2 mm, 1.27 mm pitch). Thermal resistance θJA is 160°C/W on standard 2-layer PCB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Channel A Output | High-current, rail-to-rail output capable of sourcing/sinking ±100 mA into 150Ω. |
| 2 (−IN A) | Channel A Inverting Input | Differential input node for closed-loop gain configuration; 2.5 pF input capacitance affects stability with capacitive loads. |
| 3 (+IN A) | Channel A Non-Inverting Input | High-impedance input (6 MΩ) with −0.2 V to 3.8 V common-mode range on 5V supply. |
| 4 (V−) | Negative Supply Rail | Supports single-supply (0 V) or split-supply (e.g., −5 V) operation; referenced for all internal biasing. |
| 5 (V+) | Positive Supply Rail | Accepts 2.7–11 V; PSRR of 81–96 dB suppresses supply noise coupling into signal path. |
| 6 (−IN B) | Channel B Inverting Input | Independent input for second channel; crosstalk to Channel A is −71 dB at 5 MHz. |
| 7 (+IN B) | Channel B Non-Inverting Input | Matches Channel A input specs; enables dual-channel synchronous signal processing. |
| 8 (OUT B) | Channel B Output | Electrically identical to OUT A; supports independent gain/feedback networks per channel. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed rail-to-rail output amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6619MA/NOPB | Higher 1.8 GHz GBW, 1.5 mA/channel lower quiescent current, but only single-channel and no shutdown pin. | Better suited for ultra-wideband IF amplification; not drop-in for dual-channel space-constrained layouts. | Select when bandwidth >1 GHz is required and dual-channel integration is unnecessary. |
| THS3202D | Current-feedback architecture, 1.8 GHz bandwidth, ±180 mA output, but higher 12.5 mA/channel supply current and narrower input CMVR (−2.5 V to 1.5 V on ±5 V). | Preferred for >100 MSPS ADC drivers where slew rate dominates over DC precision. | Choose for highest-speed applications where input offset voltage tolerance >±3 mV is acceptable. |
Compared with LMH6612MA/NOPB, LMH6619MA/NOPB trades dual-channel integration for higher bandwidth and lower power, while THS3202D offers superior speed at the cost of DC accuracy and supply flexibility - making LMH6612MA/NOPB optimal for balanced high-fidelity, dual-channel, low-power video and data acquisition roles.

FAQ
What is the maximum operating supply voltage for LMH6612MA/NOPB?
The LMH6612MA/NOPB supports a total supply voltage range of 2.7 V to 11 V on single supply, or ±1.35 V to ±5.5 V on split supply. Absolute maximum supply voltage is 12 V (V+ − V−), beyond which permanent damage may occur. Operation at 11 V is fully characterized and supported across the −40°C to +125°C temperature range, with PSRR maintained at 81–96 dB.
Does LMH6612MA/NOPB include a shutdown function?
No, LMH6612MA/NOPB does not include a shutdown pin. The shutdown feature is exclusive to the LMH6611 (single-channel variant); the LMH6612 is a dual-channel amplifier without enable/disable control. For power-gated dual-channel operation, external FET switching on the V+ rail or use of the LMH6611 pair is required.
What is the input common-mode voltage range of LMH6612MA/NOPB at 5V supply?
At 5 V single supply (V− = 0 V, V+ = 5 V), the LMH6612MA/NOPB input common-mode voltage range is specified as −0.2 V to 3.8 V, referenced to the negative rail. This allows inputs to extend 200 mV below ground and up to 1.2 V below V+, enabling true single-supply operation with ground-referenced sensors or AC-coupled sources without level shifting.
Can LMH6612MA/NOPB drive a 150Ω load to full rail in video applications?
Yes, LMH6612MA/NOPB drives a 150Ω load to within 49 mV of ground and 76 mV of V+ on a 5 V supply, achieving >90% of rail-to-rail swing. Its ±100 mA linear output current and 45 MHz 0.1 dB bandwidth meet SMPTE 253M/293M requirements for 720p/1080i analog video, eliminating need for external emitter followers or AC-coupling networks.
Is LMH6612MA/NOPB pin-compatible with other TI dual op-amps like OPA2350 or THS4032?
No, LMH6612MA/NOPB is not pin-compatible with OPA2350 (SOIC-8, but different pinout: OUT A/−IN A/+IN A/V−/V+/−IN B/+IN B/OUT B vs. OPA2350's OUT A/−IN A/+IN A/V+/−IN B/+IN B/OUT B/V−) or THS4032 (SOIC-8 with OUT A/−IN A/+IN A/V−/V+/−IN B/+IN B/OUT B). Pin mapping must be verified against TI's official LMH6612MA/NOPB connection diagram to avoid layout errors.
