Product details
Overview
LMH6619MAE/NOPB from Texas Instruments is a dual 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 1.25 mA per channel supply current at 5V, enabling use as an ADC driver or DAC buffer in portable video and STB systems.
For engineers reviewing the LMH6619MAE/NOPB datasheet, LMH6619MAE/NOPB pinout, LMH6619MAE/NOPB application, or LMH6619MAE/NOPB equivalent, key selection criteria include its −40°C to +125°C industrial temperature grade, 0.1% settling time of 90 ns, 10 nV/√Hz input voltage noise, and ability to swing within 77 mV of either rail on a 1 kΩ load - critical for single-supply 3.3V/5V data acquisition designs.
Technical Context
The LMH6619MAE/NOPB employs a voltage-feedback architecture with balanced differential inputs and high open-loop gain (>84 dB), supporting stable active filter design and accurate closed-loop gain accuracy. Its rail-to-rail input stage extends 200 mV beyond supply rails, while the output drives ±35 mA linearly and sustains 30 pF capacitive loads without external compensation.
Designed for wide supply operation (2.7V to 11V), it maintains 100 dBc SFDR at 100 kHz and achieves 0.1 dB flatness up to 15 MHz at AV = +2 - making it suitable for driving 10-bit to 14-bit mega-sample ADCs where dynamic range and settling fidelity are essential.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-Signal Bandwidth | 130 MHz at AV = +1, RL = 1 kΩ - supports high-frequency signal chain stages up to ~65 MHz Nyquist-limited sampling. |
| Slew Rate | 55 V/µs - enables full-scale 2 VPP output transitions in under 37 ns, minimizing distortion in fast transient signals. |
| Supply Current per Channel | 1.25 mA at VS = 5V - allows dual-channel high-speed amplification with <2.5 mA total quiescent draw for battery-sensitive applications. |
| Input Offset Voltage | ±0.75 mV max at 25°C - ensures DC accuracy in precision sensor interfaces and low-gain signal conditioning paths. |
| 0.1% Settling Time | 90 ns for 2 V step at AV = −1 - meets timing budgets for 10 MSPS+ data converters requiring sub-100 ns acquisition windows. |
| Input Voltage Noise Density | 10 nV/√Hz at 100 kHz - preserves SNR in medium-bandwidth sensor and audio preamp stages without added noise floor degradation. |
| Operating Temperature Range | −40°C to +125°C - qualified for under-hood automotive, industrial PLC, and outdoor embedded equipment deployments. |
Pinout & Package
LMH6619MAE/NOPB is housed in an 8-pin SOIC package (D0008A), with thermal resistance θJA = 160°C/W. The device contains two independent op-amp channels sharing common power rails.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting channel output; capable of sourcing/sinking ±35 mA into 1 kΩ or 150Ω loads. |
| 2 | −IN A | Inverting input of Channel A; rail-to-rail common-mode range supports single-supply biasing at mid-rail. |
| 3 | +IN A | Non-inverting input of Channel A; matched impedance to −IN A enables precision differential configurations. |
| 4 | V− | Negative supply rail connection; accepts ground or negative voltage down to −5V for split-supply operation. |
| 5 | V+ | Positive supply rail connection; operates from 2.7V to 11V, enabling direct interface with 3.3V or 5V logic domains. |
| 6 | −IN B | Inverting input of Channel B; electrically isolated from Channel A but shares V+ and V− rails. |
| 7 | +IN B | Non-inverting input of Channel B; identical DC and AC specs to +IN A for matched dual-channel performance. |
| 8 | OUT B | Non-inverting channel output; crosstalk to Channel A is −80 dB at 5 MHz, preserving channel independence. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input common-mode range extends 200 mV beyond rails; output swings to within 77 mV of either rail on 1 kΩ - maximizes dynamic range on low-voltage supplies. |
| Low Power / High Speed | 130 MHz bandwidth with only 1.25 mA per channel - achieves >100 MHz/MW efficiency, ideal for portable instrumentation. |
| High SFDR | 100 dBc at 100 kHz (2 VPP) - enables clean digitization of baseband signals for 12-bit+ ADCs without harmonic contamination. |
| Robust Capacitive Drive | Stable with up to 30 pF load capacitance - eliminates need for isolation resistors when driving ADC input capacitance or long PCB traces. |
| Industrial Temp Grade | Specified over −40°C to +125°C - supports deployment in motor control, factory automation, and automotive infotainment without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS3202DR | Higher supply current (6.5 mA/ch), wider bandwidth (520 MHz), no rail-to-rail input - requires level-shifting for single-supply use. | Better suited for RF IF amplification or ultra-high-speed pulse applications; less optimal for low-power portable ADC drivers. | Select THS3202DR only when >300 MHz bandwidth is mandatory and power budget allows ≥13 mA total. |
| OPA2835IDR | Lower supply current (1.8 mA/ch), lower noise (4.3 nV/√Hz), rail-to-rail I/O, but reduced bandwidth (31 MHz) and slower settling (140 ns). | Preferred for ultra-low-noise sensor signal chains where speed <50 MHz suffices and power optimization is critical. | Choose OPA2835IDR when noise dominates over speed - e.g., thermocouple or strain gauge amplification with 24-bit ΣΔ ADCs. |
Compared with THS3202DR and OPA2835IDR, LMH6619MAE/NOPB uniquely balances 130 MHz bandwidth, rail-to-rail operation, and sub-1.3 mA/channel consumption - making it the optimal choice for cost- and power-constrained high-speed data acquisition where full supply rail utilization is required.

FAQ
What is the maximum operating supply voltage for LMH6619MAE/NOPB?
The LMH6619MAE/NOPB supports a maximum supply voltage of 12 V (V+ − V−), with guaranteed operation from 2.7 V to 11 V. Absolute maximum rating is 12 V; exceeding this risks permanent damage. Operation at 11 V enables full dynamic range in high-voltage industrial sensor interfaces while maintaining 1.25 mA per channel supply current.
Does LMH6619MAE/NOPB support true single-supply operation with rail-to-rail input and output?
Yes, LMH6619MAE/NOPB supports true single-supply operation: input common-mode range extends 200 mV beyond both rails, and output swings to within 77 mV of either rail on a 1 kΩ load. At 5 V supply, it delivers 4.923 V maximum output and 0.077 V minimum output - enabling full-scale signal handling without level-shifting circuitry.
What is the typical crosstalk between channels in LMH6619MAE/NOPB?
LMH6619MAE/NOPB specifies −80 dB crosstalk at 5 MHz (VIN = 2 VPP), measured between Channel A and Channel B. This low inter-channel coupling ensures independent operation in dual-path signal chains such as stereo audio buffers or differential ADC driver pairs, without requiring physical separation or guard traces on PCB layout.
Can LMH6619MAE/NOPB drive a 150Ω video load while maintaining specified differential gain and phase?
Yes - LMH6619MAE/NOPB is characterized for 150Ω loads with AV = +2, delivering ≤0.1% differential gain error and ≤0.1° differential phase error at 4.43 MHz. Its output can source/sink ±35 mA and swing to within 255 mV of either rail under 150Ω loading, meeting NTSC/PAL CVBS broadcast specifications without external components.
Is LMH6619MAE/NOPB pin-compatible with other devices in the LMH661x family?
No - LMH6619MAE/NOPB (dual, 8-pin SOIC) is not pin-compatible with LMH6618 (single, 6-pin SOT-23). Pin assignments differ fundamentally: LMH6619 uses pins 1/8 for outputs and 2/3/6/7 for inputs, while LMH6618 reserves pin 6 for shutdown. Board redesign is required when substituting between these variants.
