Product details
Overview
LMH6618MKE/NOPB from Texas Instruments is a single-channel, rail-to-rail input/output operational amplifier optimized for high-speed, low-power signal conditioning in precision analog front-ends. It delivers 130 MHz small-signal bandwidth, 55 V/µs slew rate, and 0.01% settling time of 120 ns at 5V supply, with 1.25 mA supply current per channel and ±0.75 mV input offset voltage - enabling use as an ADC driver or DAC buffer in portable video and STB systems.
For engineers reviewing the LMH6618MKE/NOPB datasheet, LMH6618MKE/NOPB pinout, LMH6618MKE/NOPB application, or LMH6618MKE/NOPB equivalent, key selection criteria include its 6-pin SOT package, active-low disable pin (72 µA shutdown current), rail-to-rail swing within 37 mV of ground on 5V supply, and guaranteed operation from −40°C to +125°C industrial temperature range.
Technical Context
The LMH6618MKE/NOPB employs a voltage-feedback topology with balanced differential inputs and high open-loop gain (>98 dB), supporting stable unity-gain and inverting configurations without external compensation. Its input common-mode range extends 200 mV beyond both rails, and output drives ≥35 mA while maintaining rail-to-rail swing into 150 Ω loads.
Integrated shutdown control enables fast enable/disable transitions (ton = 25 ns, toff = 90 ns), reducing quiescent current to 72 µA in disabled state. The amplifier maintains 100 dBc SFDR at 100 kHz and 10 nV/√Hz input voltage noise, making it suitable for driving 8–14-bit mega-sample ADCs with minimal distortion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-Signal Bandwidth | 130 MHz at AV = +1, RL = 1 kΩ, 5V supply - supports wideband video and communication signals without gain peaking. |
| Slew Rate | 55 V/µs - enables clean 2-V step response with 30 ns rise/fall time and minimal slewing distortion. |
| Supply Current | 1.25 mA typical at 5V - balances speed and power for battery-sensitive applications like portable video. |
| Input Offset Voltage | ±0.75 mV max at 25°C - ensures DC accuracy in precision sensor amplification and current sense circuits. |
| Settling Time | 120 ns to 0.01% - meets timing requirements for high-resolution ADC sampling clocks up to 8.3 MSPS. |
| Output Swing | Within 37 mV of ground rail on 5V supply with 150 Ω load - maximizes dynamic range in single-supply systems. |
| Shutdown Current | 72 µA max - enables low-power sleep mode in intermittent-sampling systems without external circuitry. |
Pinout & Package
LMH6618MKE/NOPB is housed in a 6-pin SOT-23 (DDC0006A) package with exposed pad for thermal performance. Pin 1 is DISABLE (active-low), Pin 2 is IN−, Pin 3 is IN+, Pin 4 is V−, Pin 5 is V+, and Pin 6 is OUT.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (DISABLE) | Active-low shutdown control | Pulls supply current to ≤72 µA when logic low; requires ≥3.0 V threshold to enable at 5V supply. |
| 2 (IN−) | Inverting input | Differential input node with 1.5 pF capacitance and 8 MΩ input resistance - stable with capacitive source impedances. |
| 3 (IN+) | Non-inverting input | Complements IN−; common-mode range extends −0.2 V to +5.2 V on 5V supply for true single-supply operation. |
| 4 (V−) | Negative supply rail | Supports dual-supply (±1.5V to ±5.5V) or single-supply (2.7V to 11V) operation - referenced to system ground in single-rail designs. |
| 5 (V+) | Positive supply rail | Accepts up to 11V; PSRR of 104 dB suppresses supply noise coupling into signal path. |
| 6 (OUT) | Amplified output | Drives ≥35 mA, swings rail-to-rail into 1 kΩ, and remains stable with ≤30 pF capacitive loads without isolation resistors. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6612MM/NOPB | Lower bandwidth (120 MHz), higher supply current (2.3 mA), no shutdown pin - same 8-pin SOIC package as LMH6619 but single-channel. | Lacks disable function and consumes >80% more quiescent current - unsuitable for power-constrained or duty-cycled systems. | Select only if board space permits SOIC and shutdown is unnecessary; verify 120 ns settling meets ADC timing budget. |
| OPA355DBVR | Higher bandwidth (200 MHz), lower noise (7 nV/√Hz), no shutdown, 5V max supply - 5-pin SOT-23 package with different pinout (no DISABLE pin). | Cannot operate above 5.5V and lacks rail-to-rail input beyond rails - limits use in 11V industrial supplies or wide common-mode sensor interfaces. | Prefer for ultra-low-noise, high-bandwidth video paths where supply <5.5V and shutdown is not required; redesign PCB for pinout mismatch. |
Compared with LMH6618MKE/NOPB, LMH6612MM/NOPB trades shutdown capability and power efficiency for marginally lower cost in SOIC format, while OPA355DBVR offers superior speed/noise at the expense of supply voltage range and disable functionality - making LMH6618MKE/NOPB the optimal choice for 2.7–11V industrial systems requiring fast enable/disable cycling.

FAQ
What is the maximum supply voltage rating for LMH6618MKE/NOPB?
The absolute maximum supply voltage (V+ to V−) for LMH6618MKE/NOPB is 12V, with recommended operating range from 2.7V to 11V. Exceeding 12V risks permanent damage, and operation above 11V voids guaranteed specifications per the datasheet's Operating Ratings table.
Does LMH6618MKE/NOPB support true rail-to-rail input on a 5V single supply?
Yes, LMH6618MKE/NOPB supports true rail-to-rail input: its common-mode voltage range extends from −0.2 V to +5.2 V at 5V supply, meaning it accepts input signals 200 mV beyond both rails - critical for interfacing with sensors or DACs operating near supply extremes.
How does the DISABLE pin function on LMH6618MKE/NOPB?
The DISABLE pin on LMH6618MKE/NOPB is active-low: pulling it below 2.0 V (typical) disables the amplifier, reducing supply current to ≤105 µA. At 5V supply, the enable threshold is ≥3.0 V, and turn-on/turn-off times are 25 ns and 90 ns respectively - enabling rapid power gating.
Can LMH6618MKE/NOPB drive a 150 Ω video load while maintaining rail-to-rail output swing?
Yes, LMH6618MKE/NOPB delivers rail-to-rail output swing into 150 Ω loads: on a 5V supply, it swings to within 250 mV of either rail (250 mV from V−, 295 mV from V+) - sufficient for standard 1 VPP video signals terminated to 150 Ω, with 0.1% differential gain/phase error at 4.43 MHz.
What is the guaranteed 0.01% settling time specification for LMH6618MKE/NOPB?
The LMH6618MKE/NOPB guarantees 120 ns 0.01% settling time for a 2V step input under inverting configuration (AV = −1), RL = 1 kΩ, and 5V supply - verified across −40°C to +125°C, making it suitable for high-speed data acquisition systems sampling at ≥8.3 MSPS.
