Product details
Overview
LMH6601QMGX/NOPB from Texas Instruments is a 250-MHz, rail-to-rail output, voltage-feedback operational amplifier optimized for low-voltage (2.4 V to 5.5 V) video and high-speed analog signal conditioning. It delivers 125 MHz small-signal bandwidth at gain +2, 260 V/μs slew rate, and 0.25%/0.25° differential gain/phase - enabling HDTV line driver and set-top box applications with minimal distortion.
For engineers reviewing the LMH6601QMGX/NOPB datasheet, LMH6601QMGX/NOPB pinout, LMH6601QMGX/NOPB application, or LMH6601QMGX/NOPB equivalent, this page provides verified specifications, SC70-6 package layout, shutdown functionality details, and automotive-grade alternatives aligned with AEC-Q100 Grade 3 requirements.
Technical Context
The LMH6601QMGX/NOPB uses a CMOS input stage with 50 pA max input bias current and 10–12 nV/√Hz input voltage noise, supporting transimpedance and high-impedance buffer roles. Its micropower shutdown mode reduces supply current to 100 nA while maintaining >100 MΩ output isolation and <1.6 V turn-on glitch at 3.3 V supply.
It operates across −40°C to +85°C ambient temperature with rail-to-rail output swing into 150 Ω loads, and features stable unity-gain compensation (125–155 MHz GBWP) and 50 pF capacitive load tolerance - eliminating need for external isolation resistors in most video driver configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-Signal Bandwidth | 125 MHz at AV = +2, 5 V supply - supports HD video signal amplification up to 1080i without attenuation |
| Slew Rate | 260 V/μs - enables clean 2-V step response in ≤2.7 ns, critical for fast-settling video DAC buffers |
| Differential Gain / Phase | 0.25% / 0.25° at 4.43 MHz - meets NTSC/PAL broadcast video fidelity requirements |
| Supply Voltage Range | 2.4 V to 5.5 V single supply - compatible with modern low-voltage SoC I/O domains and battery-powered systems |
| Shutdown Current | 100 nA - allows power gating in portable or always-on video subsystems without leakage penalty |
| Input Bias Current | 50 pA max - preserves accuracy in high-Z sensor interfaces and photodiode transimpedance amplifiers |
| Output Drive | 100 mA continuous - drives dual 75 Ω video lines or 150 Ω loads directly without external buffering |
Pinout & Package
LMH6601QMGX/NOPB is housed in a 6-pin SC70 package (2.00 mm × 1.25 mm body size), optimized for space-constrained video routing and high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUTPUT | Amplifier output | Delivers rail-to-rail swing into 150 Ω; low 0.2 Ω enabled output resistance minimizes insertion loss |
| 2 - V− | Negative supply | Ground reference for single-supply operation; accepts 0 V (GND) or negative rail down to −2.5 V differential |
| 3 - +IN | Noninverting input | High-impedance CMOS node (15 TΩ at 3.3 V); supports DC-coupled sensor or DAC interface |
| 4 - −IN | Inverting input | Feedback node for precision gain configuration; matched to +IN for low input offset drift |
| 5 - SD | Shutdown control | CMOS-compatible logic input; <0.33 V disables amplifier, >2.97 V enables - no external pull-up required |
| 6 - V+ | Positive supply | Accepts 2.4–5.5 V; PSRR >57 dB ensures immunity to digital supply noise in mixed-signal systems |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Swings within 125 mV of V− and 190 mV of V+ into 150 Ω - preserves full dynamic range in 3.3 V video systems |
| Micropower shutdown | Reduces ICC from 11 mA to 100 nA while maintaining >60 dB off-isolation at 1 MHz - ideal for power-gated video paths |
| Low distortion at 10 MHz | THD = −66 dBc (3.3 V, RL = 1 kΩ), enabling clean RF IF amplification and high-fidelity ADC driver stages |
| Stable with capacitive loads | Tolerates ≥50 pF directly on output - eliminates need for series resistor in LCD timing or camera module interfaces |
| AEC-Q100 qualified | LMH6601-Q1 variant meets Grade 3 (−40°C to +85°C) automotive requirements; QMGX/NOPB shares identical die and SC70 packaging |

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 bandwidth but requires ≥5 V supply; no shutdown function; SO-8 package (larger footprint) | Better suited for RF IF stages above 100 MHz; not viable for 2.4–3.3 V battery-powered video systems | Select when bandwidth >250 MHz is mandatory and shutdown is unnecessary; verify PCB layout change for SO-8 vs SC70 |
| OPA355DBVR | Lower 200-MHz bandwidth, 150 V/μs slew rate, and no shutdown; same SC70-6 package and 2.5–5.5 V supply range | Cost-optimized alternative for non-critical video paths where 0.25° phase error margin is relaxed | Choose for cost-sensitive consumer electronics where LMH6601QMGX/NOPB's differential phase spec is over-engineered |
Compared with LMH6601QMGX/NOPB, LMH6609MF/NOPB trades shutdown capability and low-voltage operation for higher bandwidth, while OPA355DBVR retains SC70 compatibility but sacrifices video-grade distortion performance - making LMH6601QMGX/NOPB the optimal balance of speed, power, package, and broadcast fidelity.

FAQ
What is the operating temperature range for LMH6601QMGX/NOPB?
The LMH6601QMGX/NOPB is specified for operation from −40°C to +85°C ambient temperature. This matches the AEC-Q100 Grade 3 qualification of the LMH6601-Q1 variant and ensures reliability in industrial and consumer environments where thermal cycling occurs, such as set-top boxes and automotive camera modules. The device maintains its 125 MHz bandwidth and 0.25° differential phase spec across this full range.
Does LMH6601QMGX/NOPB support true single-supply operation with rail-to-rail input?
No - LMH6601QMGX/NOPB features rail-to-rail *output* but not rail-to-rail *input*. Its common-mode input voltage range extends from V− − 0.20 V to V+ − 1.5 V (e.g., 0 V to 3.5 V at 5 V supply). This allows DC-coupled operation with ground-referenced sources when V− = GND, but prohibits direct connection to V+ without level shifting. Input bias current remains ≤50 pA across the valid CMVR.
How does the shutdown pin (Pin 5) behave electrically on LMH6601QMGX/NOPB?
Pin 5 (SD) is a CMOS-compatible digital input: driving it below 0.33 V (at 3.3 V supply) disables the amplifier, reducing supply current to 100 nA and raising output impedance to >100 MΩ. Driving it above 2.97 V enables normal operation. Logic current is ≤8 pA, eliminating need for pull-up resistors. Turnon glitch is limited to 1.6 V peak, preventing false triggering in noise-prone systems.
Can LMH6601QMGX/NOPB drive a 75 Ω load directly in a video application?
Yes - LMH6601QMGX/NOPB delivers 100 mA continuous output current and is characterized into 150 Ω and 75 Ω loads. When driving dual 75 Ω coaxial lines (150 Ω total), it maintains 0.25% differential gain and 125 MHz bandwidth at 4.43 MHz. Output resistance is 0.2 Ω in active mode, minimizing voltage drop and ensuring flat frequency response without external series resistors.
Is LMH6601QMGX/NOPB pin-compatible with other SC70-6 op-amps like OPA355 or TLV2372?
No - LMH6601QMGX/NOPB has a unique pinout: OUTPUT (1), V− (2), +IN (3), −IN (4), SD (5), V+ (6). OPA355DBVR uses OUTPUT (1), V− (2), −IN (3), +IN (4), V+ (5), NC (6); TLV2372 uses different pin assignments and lacks shutdown. Direct replacement requires PCB redesign. Always verify pin mapping using TI's DCK package drawing before board layout.
