Product details
Overview
LMH6601QMG/NOPB from Texas Instruments is a 250-MHz, 2.4-V CMOS operational amplifier with shutdown, designed for high-speed video line driving and transimpedance amplification. It delivers 125 MHz small-signal bandwidth at AV = +2, 260 V/μs slew rate, rail-to-rail output swing, and operates from 2.4 V to 5.5 V single supply - enabling HDTV line driver and automotive camera interface applications.
For engineers reviewing the LMH6601QMG/NOPB datasheet, LMH6601QMG/NOPB pinout, LMH6601QMG/NOPB application, or LMH6601QMG/NOPB equivalent, key selection criteria include its 75 MHz large-signal bandwidth, 0.25%/0.25° differential gain/phase performance at 4.43 MHz, 50 pF capacitive load tolerance, and guaranteed 100 mA output current into 150 Ω loads.
Technical Context
The LMH6601QMG/NOPB employs a voltage-feedback architecture optimized for low-voltage, high-speed operation. Its CMOS input stage enables 50 pA max input bias current and >10 TΩ input resistance, while the rail-to-rail output stage supports full dynamic range in single-supply systems down to 2.4 V.
Integrated micropower shutdown (100 nA quiescent current) is controlled via a CMOS-compatible logic input (Pin 5), with defined enable/disable voltage thresholds (e.g., VDMIN = 2.97 V at 3.3 V supply). The device maintains stable unity-gain operation with ≥50 pF capacitive load tolerance and exhibits <10% overshoot in step response.

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 | Higher 450-MHz GBW, no shutdown, SOT-23-5 package | Lacks micropower disable; better suited for always-on high-gain stages than power-cycled video drivers | Select when shutdown is unnecessary and higher closed-loop bandwidth is required |
| THS3201DGN | Current-feedback architecture, 1.8-GHz BW, 4000-V/μs slew, SOIC-8 | Requires careful layout due to CFB sensitivity; higher power (12.5 mA vs 11 mA) and larger footprint | Select for ultra-high-speed (>100 MHz) non-inverting gain ≥5 applications where layout control is feasible |
Compared with LMH6601QMG/NOPB, LMH6609MF/NOPB trades shutdown capability for higher bandwidth and simpler biasing, while THS3201DGN offers order-of-magnitude faster slew but demands strict layout discipline and lacks rail-to-rail output - making LMH6601QMG/NOPB optimal for compact, low-voltage, power-aware video line driving.

FAQ
What is the maximum supply voltage for LMH6601QMG/NOPB?
The absolute maximum supply voltage (V+ – V−) for LMH6601QMG/NOPB is 6 V, but the recommended operating range is 2.4 V to 5.5 V. Operation above 5.5 V risks permanent damage per TI's Absolute Maximum Ratings table. At 5 V supply, LMH6601QMG/NOPB achieves 130 MHz small-signal bandwidth and 275 V/μs slew rate - values that decrease slightly at lower voltages (e.g., 120 MHz at 2.7 V).
Does LMH6601QMG/NOPB support rail-to-rail input?
No, LMH6601QMG/NOPB does not support rail-to-rail input. Its common-mode input voltage range (CMVR) is specified as V− – 0.20 V to V+ – 1.5 V - meaning the inputs must remain at least 1.5 V below V+ for proper operation. However, it does provide true rail-to-rail output swing, reaching within 125 mV of V− and 190 mV of V+ under 150 Ω load conditions.
How does the shutdown function behave on LMH6601QMG/NOPB?
The shutdown pin (Pin 5) of LMH6601QMG/NOPB is CMOS-compatible: tying it to ≤0.33 V (at 3.3 V supply) disables the amplifier, reducing supply current to 100 nA and placing the output in high-impedance state (>100 MΩ). Tying it to ≥2.97 V enables normal operation. Turnon time is 3.5 µs and turnoff is 500 ns at 3.3 V, enabling fast power gating in multi-channel video systems.
Can LMH6601QMG/NOPB drive a 75 Ω load directly?
Yes, LMH6601QMG/NOPB is explicitly characterized driving 150 Ω loads (dual 75 Ω in parallel), delivering ±100 mA output current. Its output resistance is 0.2 Ω when enabled, and it maintains 0.1-dB gain flatness to 30 MHz into 150 Ω. For single 75 Ω termination, use series matching (e.g., 75 Ω resistor at output) to avoid peaking; the device remains stable with ≥50 pF capacitive load.
Is LMH6601QMG/NOPB qualified for automotive applications?
LMH6601QMG/NOPB is the commercial-grade version; the automotive-qualified variant is LMH6601-Q1 (AEC-Q100 Grade 3, −40°C to +85°C). While LMH6601QMG/NOPB shares identical electrical specs and SC70 packaging, it is not certified to AEC-Q100. For automotive camera or ADAS designs requiring qualification, LMH6601-Q1 must be selected - LMH6601QMG/NOPB is intended for industrial and consumer video systems.
