Product details
Overview
LMH6619QMAKE/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, 1.25 mA per-channel supply current at 5 V, ±0.75 mV max input offset voltage (25°C), and operates from 2.7 V to 11 V. It serves as an ADC driver in 12-bit mega-sample data acquisition systems.
For engineers reviewing the LMH6619QMAKE/NOPB datasheet, LMH6619QMAKE/NOPB pinout, LMH6619QMAKE/NOPB application, or LMH6619QMAKE/NOPB equivalent, key selection criteria include its AEC-Q100 Grade 2 qualification (−40°C to +105°C), 0.01% settling time of 120 ns, 100 dBc SFDR at 100 kHz, and ability to drive 150 Ω video loads with <0.1% differential gain/phase error.
Technical Context
The LMH6619QMAKE/NOPB uses a voltage-feedback topology with balanced inputs and high open-loop gain (>98 dB), enabling precision active filter design and stable unity-gain operation. Its input common-mode range extends 200 mV beyond both rails, and output swings to within 37 mV of ground on a 5 V single supply with 150 Ω termination.
It features internal compensation for driving up to 30 pF capacitive loads without external components, supports linear ±35 mA output current, and maintains 15 MHz 0.1 dB bandwidth at AV = +2 - critical for composite video and high-fidelity DAC buffering applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal BW | 130 MHz at AV = +1, RL = 1 kΩ - enables wideband sensor signal amplification and fast transient response. |
| Slew rate | 55 V/µs - supports clean 2 VPP step reproduction with minimal distortion in video and ADC front-ends. |
| Supply current | 1.25 mA per channel at 5 V - allows dual-channel high-speed performance within tight power budgets. |
| Input offset voltage | ±0.75 mV max at 25°C - ensures DC accuracy in precision transducer interfaces and current sense circuits. |
| 0.01% settling time | 120 ns - meets timing requirements for 10+ MSPS ADC sampling with guaranteed acquisition fidelity. |
| SFDR | 100 dBc at f = 100 kHz, VOUT = 2 VPP - preserves dynamic range in high-resolution analog front-ends. |
| Rail-to-rail I/O | Input CMVR = −0.2 V to 5.2 V, output swing to within 37 mV of rails - maximizes signal swing on low-voltage supplies. |
Pinout & Package
LMH6619QMAKE/NOPB is housed in an 8-pin SOIC package (SOIC-8, 3.9 mm × 4.9 mm, 1.27 mm pitch) with standard surface-mount footprint and thermal resistance θJA = 160°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT B) | Channel B output | Delivers amplified, rail-to-rail output signal; capable of sourcing/sinking ±35 mA into 150 Ω loads. |
| 2 (–IN B) | Channel B inverting input | Differential input node; high impedance (8 MΩ) and low capacitance (1.5 pF) minimize loading in feedback networks. |
| 3 (+IN B) | Channel B non-inverting input | Accepts rail-to-rail common-mode signals; extends 200 mV beyond supply rails for single-supply flexibility. |
| 4 (V–) | Negative supply rail | Supports dual-supply (±1.5 V to ±5.5 V) or single-supply (ground reference) operation. |
| 5 (V+) | Positive supply rail | Operates from 2.7 V to 11 V; PSRR >84 dB ensures immunity to supply noise in noisy environments. |
| 6 (–IN A) | Channel A inverting input | Electrically isolated from Channel B; crosstalk rejection >80 dB at 5 MHz prevents inter-channel interference. |
| 7 (+IN A) | Channel A non-inverting input | Matches Pin 3 characteristics; enables matched dual-channel configurations for differential signaling. |
| 8 (OUT A) | Channel A output | Independent output stage; drives complex loads (e.g., 150 Ω || 30 pF) without external compensation. |
Key Features
| Feature | Design Value |
|---|---|

FAQ
What is the operating temperature range for LMH6619QMAKE/NOPB?
The LMH6619QMAKE/NOPB is AEC-Q100 Grade 2 qualified and specified to operate reliably from −40°C to +105°C ambient temperature. This range is validated across all electrical parameters including input offset voltage, bandwidth, and output drive capability - making it suitable for under-hood automotive electronics and industrial control environments.
Does LMH6619QMAKE/NOPB support single-supply operation?
Yes, LMH6619QMAKE/NOPB fully supports true single-supply operation. Its rail-to-rail input common-mode range extends 200 mV beyond both supply rails (e.g., −0.2 V to 5.2 V on 5 V), and its output swings to within 37 mV of ground with a 150 Ω load - enabling direct interfacing with 3.3 V or 5 V microcontrollers and ADCs without level-shifting circuitry.
What load can LMH6619QMAKE/NOPB drive without external compensation?
LMH6619QMAKE/NOPB can drive up to 30 pF capacitive loads directly, as confirmed by TI's characterization data and stability analysis. When driving heavier capacitive loads (e.g., >30 pF) or low-impedance video cables (e.g., 75 Ω), a small series isolation resistor (RISO) of 25–75 Ω is recommended to maintain phase margin and prevent peaking - detailed in Figure 12 of the SNOSC78A datasheet.
Is LMH6619QMAKE/NOPB pin-compatible with other dual op-amps in SOIC-8?
No - LMH6619QMAKE/NOPB has a specific pinout (OUT B, –IN B, +IN B, V–, V+, –IN A, +IN A, OUT A) optimized for dual-channel symmetry and layout isolation. It is not pin-compatible with generic SOIC-8 op-amps like LM358 or TLV2462. Board redesign is required for substitution unless the alternate part explicitly states identical pin mapping.
How does LMH6619QMAKE/NOPB perform in video applications?
LMH6619QMAKE/NOPB delivers broadcast-grade video performance: 0.1% differential gain and 0.1° differential phase error at 4.43 MHz, 15 MHz 0.1 dB bandwidth at AV = +2, and <0.01% THD+N at 1 MHz. These characteristics meet NTSC/PAL specifications for STB, TV, and portable video outputs - verified under 5 V supply and 150 Ω load conditions.
