Product details
Overview
LMH6639MAX/NOPB from Texas Instruments is a 190MHz rail-to-rail output voltage-feedback operational amplifier with shutdown control, 3.6mA supply current (enabled), 400μA in shutdown, 172V/μs slew rate, and 110mA linear output current - designed for high-speed video buffering, ADC driving, and portable video systems operating from 3V to 12V supplies.
For engineers reviewing the LMH6639MAX/NOPB datasheet, LMH6639MAX/NOPB pinout, LMH6639MAX/NOPB application, or LMH6639MAX/NOPB equivalent, key selection criteria include rail-to-rail output swing (40mV from rails), fast settling time (33ns), low THD (−60dBc at 5MHz), differential gain/phase accuracy (0.12%/0.045°), and shutdown isolation (−70dB at 1MHz).
Technical Context
The LMH6639MAX/NOPB uses TI's VIP10 process to achieve high bandwidth with low quiescent current. Its voltage-feedback architecture supports stable operation at unity gain (AV = +1) and provides full-power bandwidth of 28MHz at 5V supply, enabling accurate amplification of fast transient signals without phase reversal across its −0.2V to 4V input common-mode range.
Integrated anti-parallel input diodes and series resistors protect against overvoltage, while the dedicated SD pin enables precise timing control with 83ns turn-on and 160ns turn-off delays. Output resistance remains below 0.2Ω at 1kHz, ensuring minimal signal degradation into 150Ω video loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| −3dB Bandwidth | 190MHz at AV = +1, 5V supply - supports high-definition video signal amplification without attenuation. |
| Slew Rate | 172V/μs - enables faithful reproduction of fast edges in pulse and composite video signals. |
| Settling Time | 33ns to ±0.1% - critical for multiplexed video or data-acquisition systems requiring rapid channel switching. |
| Output Swing | Within 40mV of either rail at 5V supply - maximizes dynamic range in single-supply 3.3V/5V systems. |
| THD | −60dBc at 5MHz, AV = +2 - meets NTSC/PAL video distortion requirements for broadcast-grade analog interfaces. |
| Differential Gain/Phase | 0.12% / 0.045° at NTSC, RL = 150Ω - ensures color fidelity in video line drivers and RGB amplifiers. |
| Supply Current (Enabled) | 3.6mA typical - balances speed and power efficiency for battery-powered portable video equipment. |
| Shutdown Current | 400μA - enables low-power standby in multi-channel video systems during inactive periods. |
Pinout & Package
LMH6639MAX/NOPB is packaged in SOIC-8 (8-pin small-outline integrated circuit), with exposed pad not present and RoHS-compliant lead finish (NOPB). Pin functions are validated per TI SNOS989G Rev. MARCH 2013.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - V+ | Positive Supply Rail | Accepts 3V to 12V single supply or +5V in dual-supply configurations; powers internal bias and output stage. |
| 2 - IN− | Inverting Input | Differential input node; used in inverting configurations or feedback networks; protected by series resistor and anti-parallel diodes. |
| 3 - IN+ | Non-Inverting Input | Differential input node; accepts common-mode voltages from −0.2V to 4V (5V supply); ESD-protected. |
| 4 - V− | Negative Supply Rail | Ground reference in single-supply mode; −5V in split-supply; defines lower output swing limit and input CMVR floor. |
| 5 - OUTPUT | Amplified Output | Rail-to-rail capable (40mV from rails); drives 150Ω video loads with <0.2Ω closed-loop output impedance at 1kHz. |
| 6 - N/C | No Connect | Internally unused; must be left floating or tied to ground per layout guidelines to avoid parasitic coupling. |
| 7 - N/C | No Connect | Internally unused; no electrical connection; PCB trace should avoid routing near sensitive analog nodes. |
| 8 - SD | Shutdown Control Input | Active-low logic interface; device disables when SD ≤ V+ − 1.65V; draws −30μA when pulled to 0V. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers 4.97V high / 25mV low swing on 5V supply - preserves full signal headroom in low-voltage video chains. |
| Input common-mode range | Extends to −0.2V below V− and within 1V of V+ - enables true single-supply operation with ground-referenced inputs. |
| Shutdown isolation | −70dB at 1MHz - suppresses crosstalk in multiplexed video or data acquisition channels during inactive states. |
| No output phase reversal | Maintains polarity integrity across full CMVR (−0.2V to 4V) - prevents signal inversion artifacts in precision buffer applications. |
| Overdrive recovery | 33ns settling after overload - ensures clean reacquisition following large transient excursions in ADC front-ends. |
| ESD-protected inputs | 2kV HBM rating with anti-parallel diode + series resistor network - reduces need for external protection in handheld designs. |
Applications
| Video Line Driver | ADC Input Buffer |
|---|---|
|

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 |
|---|---|---|---|
| LMH6642MA/NOPB | Higher supply current (6.5mA), wider GBW (1.8GHz), no shutdown pin - optimized for RF IF stages. | Lacks shutdown control and consumes >1.8× more current; unsuitable for power-sensitive portable video. | Select only when >1GHz bandwidth is required and shutdown functionality is unnecessary. |
| OPA695IDBVR | Higher slew rate (4300V/μs), higher THD (−45dBc), no rail-to-rail output - designed for ultra-wideband IF amps. | Cannot swing within 40mV of rails; requires dual supply; incompatible with single-supply 3.3V/5V video systems. | Choose only for non-rail-to-rail, high-slew-rate applications where output headroom is not constrained. |
Compared with LMH6639MAX/NOPB, LMH6642MA/NOPB trades shutdown capability and low quiescent current for extreme bandwidth, while OPA695IDBVR sacrifices rail-to-rail output and low-distortion video performance for raw slew rate - making LMH6639MAX/NOPB uniquely balanced for portable video and precision ADC buffering.

FAQ
What is the maximum supply voltage for LMH6639MAX/NOPB?
The absolute maximum supply voltage (V+ to V−) for LMH6639MAX/NOPB is 13.5V. The recommended operating range is 3V to 12V, with full specifications guaranteed across this span. Exceeding 13.5V risks permanent damage to the internal VIP10 process transistors, as confirmed in the Absolute Maximum Ratings table of TI SNOS989G.
Does LMH6639MAX/NOPB support rail-to-rail input operation?
No, LMH6639MAX/NOPB does not support rail-to-rail input operation. Its input common-mode voltage range is specified as −0.2V to 4V with a 5V supply - meaning it operates down to 0.2V below V− but only up to 1V below V+. It is a rail-to-rail *output* amplifier, not a rail-to-rail *input/output* device.
What is the shutdown threshold voltage for LMH6639MAX/NOPB?
The shutdown threshold voltage for LMH6639MAX/NOPB is V+ − 1.65V (typical) at 5V supply, meaning the SD pin must be pulled below ~3.35V to activate shutdown mode. This threshold is supply-referenced, ensuring consistent behavior across 3V–12V operation, and is verified in the 5V Electrical Characteristics table of the datasheet.
Can LMH6639MAX/NOPB drive a 150Ω load at full output swing?
Yes, LMH6639MAX/NOPB is fully characterized driving 150Ω loads: at 5V supply, it delivers 4.65V high and 85mV low output swing (VID = ±200mV), with 0.12% differential gain and 0.045° differential phase - confirming robust 150Ω video-line drive capability per TI's NTSC test conditions in SNOS989G.
Is LMH6639MAX/NOPB pin-compatible with other SOIC-8 op-amps?
LMH6639MAX/NOPB has a nonstandard SOIC-8 pinout: pins 6 and 7 are No Connect, and shutdown is on pin 8 - unlike industry-standard dual/op-amp layouts. It is not pin-compatible with generic SOIC-8 op-amps such as TL072 or OPA2350; PCB layout must follow TI's Figure 3 connection diagram to ensure correct V+, IN−, IN+, V−, OUTPUT, and SD placement.
