Product details
Overview
LMH6619QMAK/NOPB from Texas Instruments is a dual, rail-to-rail input/output operational amplifier optimized for high-speed, low-power signal conditioning in automotive and industrial systems. It delivers 130 MHz small-signal bandwidth, 55 V/µs slew rate, and 1.25 mA per-channel supply current at 5 V, with ±0.75 mV input offset voltage and 100 dBc SFDR at 100 kHz - enabling precision ADC driving and video buffering in single-supply 2.7–11 V applications.
For engineers reviewing the LMH6619QMAK/NOPB datasheet, LMH6619QMAK/NOPB pinout, LMH6619QMAK/NOPB application, or LMH6619QMAK/NOPB equivalent, this page provides verified technical context, AEC-Q100 Grade 2 qualification details, SOIC-8 package layout, real-world settling time (90 ns to 0.1%), and validated alternatives for ADC driver, DAC buffer, and active filter designs.
Technical Context
The LMH6619QMAK/NOPB uses voltage-feedback topology with balanced differential inputs and high open-loop gain (>98 dB), supporting stable unity-gain and higher-gain configurations without external compensation. Its rail-to-rail input extends 200 mV beyond supply rails, and output swings within 37 mV of ground on 5 V with 150 Ω load - enabling true single-supply operation.
Designed for driving complex capacitive loads up to 30 pF and sourcing/sinking ±35 mA linearly, it maintains 15 MHz 0.1 dB bandwidth at AV = +2 and achieves 120 ns 0.01% settling time. The amplifier is characterized across −40°C to +105°C and qualified to AEC-Q100 Grade 2 standards for automotive use.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-Signal Bandwidth | 130 MHz at AV = +1, RL = 1 kΩ - supports wideband signal acquisition and video-frequency amplification. |
| Slew Rate | 55 V/µs typical - enables fast transient response for high-fidelity pulse and step signals. |
| Supply Current per Channel | 1.25 mA at VS = 5 V - balances speed and power efficiency for battery-sensitive or thermally constrained designs. |
| Input Offset Voltage | ±0.75 mV max at 25°C - ensures DC accuracy in precision sensor interfaces and current-sense amplifiers. |
| 0.1% Settling Time | 90 ns at AV = −1, 2 V step - critical for high-throughput ADC sampling with minimal acquisition dead time. |
| Spurious-Free Dynamic Range | 100 dBc at f = 100 kHz, VOUT = 2 VPP - preserves SNR in 12-bit+ data conversion front-ends. |
| Rail-to-Rail I/O | Input CMVR extends −0.2 V to +5.2 V (5 V supply); output swings to within 77 mV of either rail - maximizes dynamic range on low-voltage rails. |
Pinout & Package
LMH6619QMAK/NOPB is housed in an 8-pin SOIC package (SOIC-8, body width 3.9 mm), rated for −40°C to +105°C operation and compliant with AEC-Q100 Grade 2 automotive reliability requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT B) | Channel B output | Drives loads up to 35 mA; rail-to-rail swing supports direct interface to ADC inputs or video lines. |
| 2 (−IN B) | Inverting input, Channel B | Differential pair node; high impedance (8 MΩ) and low input capacitance (1.5 pF) minimize loading on feedback networks. |
| 3 (+IN B) | Non-inverting input, Channel B | Accepts common-mode voltages from −0.2 V to +5.2 V on 5 V supply - enables ground-referenced sensor signal conditioning. |
| 4 (V−) | Negative supply rail | Supports single-supply (0 V) or split-supply (e.g., −5 V) operation; ESD-protected to 2000 V HBM. |
| 5 (V+) | Positive supply rail | Operates from 2.7 V to 11 V; PSRR >104 dB suppresses supply noise in noisy automotive environments. |
| 6 (−IN A) | Inverting input, Channel A | Electrically isolated from Channel B; crosstalk rejection >80 dB at 5 MHz prevents inter-channel interference. |
| 7 (+IN A) | Non-inverting input, Channel A | Matches Pin 3 performance; allows independent biasing for dual-path signal chains (e.g., I/Q processing). |
| 8 (OUT A) | Channel A output | Identical AC/DC specs to Pin 1; supports dual-channel applications like differential ADC drivers or stereo audio buffers. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 2 qualification | Validated for −40°C to +105°C ambient operation in automotive ECUs and ADAS sensors - no derating required. |
| Rail-to-rail input and output | Enables full-scale signal utilization on 3.3 V or 5 V supplies, eliminating level-shifting circuitry in portable video and STB designs. |
| 130 MHz bandwidth with 1.25 mA/ch | Delivers >10× better bandwidth-per-mA than legacy high-speed op-amps - reduces thermal load in multi-channel modules. |
| 100 dBc SFDR at 100 kHz | Meets dynamic range requirements for 14-bit mega-sample ADCs without external filtering or calibration. |
| Stable driving of 30 pF loads | Eliminates need for external isolation resistors when interfacing to ADC input capacitance or long PCB traces. |
| 0.1% settling in 90 ns | Reduces acquisition window by >30% vs. comparable amplifiers - increases effective sampling rate in time-interleaved systems. |

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 |
|---|---|---|---|
| LMH6612QMA/NOPB | Single-channel version; identical bandwidth (130 MHz), slew rate (55 V/µs), and AEC-Q100 Grade 2 rating - same die in smaller SOIC-8 footprint. | Used where space-constrained PCBs require single-amplifier placement or channel count reduction. | Select when only one high-speed channel is needed; saves board area but lacks dual-channel correlation benefits. |
| THS3201DGNR | Higher bandwidth (1.8 GHz) and slew rate (6000 V/µs), but 12 mA/ch supply current and no rail-to-rail input - requires ±5 V supplies and external level shifting. | Targeted at RF/IF signal chains where ultra-wideband gain is prioritized over power and DC precision. | Choose only for >100 MHz small-signal amplification where LMH6619QMAK/NOPB's 130 MHz limit is insufficient. |
Compared with LMH6619QMAK/NOPB, LMH6612QMA/NOPB offers identical performance in half the channel count and footprint, while THS3201DGNR trades 10× higher power and loss of rail-to-rail capability for extreme bandwidth - making LMH6619QMAK/NOPB optimal for power-aware, precision high-speed analog front-ends.

FAQ
What is the operating temperature range for LMH6619QMAK/NOPB?
The LMH6619QMAK/NOPB is AEC-Q100 Grade 2 qualified and specified for continuous operation from −40°C to +105°C ambient temperature. This range is fully tested and guaranteed per TI's automotive qualification flow, making LMH6619QMAK/NOPB suitable for under-hood and infotainment applications without derating.
Does LMH6619QMAK/NOPB support single-supply operation?
Yes, LMH6619QMAK/NOPB supports true single-supply operation from 2.7 V to 11 V. Its rail-to-rail input accepts common-mode voltages 200 mV beyond both supply rails, and its output swings to within 37 mV of ground on a 5 V supply with 150 Ω load - enabling direct interface to unipolar ADCs and microcontroller inputs.
What is the maximum capacitive load LMH6619QMAK/NOPB can drive without instability?
LMH6619QMAK/NOPB is designed to drive capacitive loads up to 30 pF while maintaining stability and specified performance. For loads exceeding 30 pF, TI recommends adding a series isolation resistor (RISO) at the output - values from 25 Ω to 100 Ω are validated in the datasheet for CL = 100 pF.
How does LMH6619QMAK/NOPB compare to standard op-amps in ADC driver applications?
LMH6619QMAK/NOPB outperforms standard op-amps in ADC driver roles via 90 ns 0.1% settling time, 100 dBc SFDR at 100 kHz, and rail-to-rail output swing - all at just 1.25 mA/ch supply current. These traits directly reduce aperture uncertainty, preserve ENOB, and eliminate external level-shifting components required by non-rail-to-rail amplifiers.
Is LMH6619QMAK/NOPB pin-compatible with other TI dual op-amps?
No, LMH6619QMAK/NOPB uses a proprietary dual-channel SOIC-8 pinout (OUT B, −IN B, +IN B, V−, V+, −IN A, +IN A, OUT A) not shared with TI's general-purpose or precision op-amp families. Layout reuse requires verification against the official pin diagram in SNOSC78A - especially critical for V−/V+ placement and channel separation.
