Product details
Overview
LMH6619MAX/NOPB from Texas Instruments is a dual, rail-to-rail input and 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 LMH6619MAX/NOPB datasheet, LMH6619MAX/NOPB pinout, LMH6619MAX/NOPB application, or LMH6619MAX/NOPB equivalent, key selection criteria include its 130 MHz bandwidth at AV = +1, ±0.75 mV input offset voltage (max), 120 ns 0.01% settling time, rail-to-rail swing within 37 mV of rails on 5V supply, and −40°C to +125°C industrial temperature grade.
Technical Context
The LMH6619MAX/NOPB employs a voltage-feedback architecture with balanced inputs and high open-loop gain (>84 dB), supporting stable active filter design and accurate closed-loop gain control. Its input common-mode range extends 200 mV beyond both supply rails, and output drives up to 35 mA while maintaining rail-to-rail swing into 1 kΩ loads.
Designed for single-supply operation down to 2.7V, it achieves true dynamic range preservation: on 5V, output swings to within 77 mV of either rail under mid-rail termination, and to within 37 mV of ground with 150 Ω ground-terminated load. SFDR of 100 dBc at 100 kHz confirms suitability for 12-bit+ ADC interfacing.
Key Specifications

Pinout & Package
LMH6619MAX/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 (A and B) sharing power pins.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives ADC input, video line, or filter stage with rail-to-rail swing capability |
| 2 | −IN A | Inverting input of Channel A - used for unity-gain inverter, transimpedance, or differential configuration |
| 3 | +IN A | Non-inverting input of Channel A - accepts rail-to-rail common-mode signals up to 5.2 V on 5V supply |
| 4 | V− | Negative supply rail - connects to GND (single supply) or negative rail (dual supply); supports −5 V minimum |
| 5 | V+ | Positive supply rail - accepts 2.7 V to 11 V; powers both channels and enables rail-to-rail I/O operation |
| 6 | −IN B | Inverting input of Channel B - electrically isolated from Channel A; enables dual-path signal processing |
| 7 | +IN B | Non-inverting input of Channel B - identical CMVR and bias specs as Channel A; supports independent signal routing |
| 8 | OUT B | Amplifier B output - provides second high-speed path for stereo audio, dual ADC channels, or redundancy |

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 |
|---|---|---|---|
| LMH6629MA/NOPB | Higher 1.5 GHz GBW, 1.8 mA/ch supply current, no rail-to-rail input - requires level-shifted input signals | Better suited for post-filter gain stages or IF amplification where input swing is constrained | Select when >200 MHz small-signal bandwidth is required and input common-mode range can be managed externally |
| OPA2835IDGKT | Lower 31 MHz bandwidth, 1.8 mA/ch, rail-to-rail I/O, 4.8 nV/√Hz noise - optimized for ultra-low-noise, not speed | Ideal for precision instrumentation where noise dominates over bandwidth requirements | Choose when sub-10 nV/√Hz noise and <1 µV offset are prioritized over 130 MHz bandwidth |
Compared with LMH6619MAX/NOPB, LMH6629MA/NOPB trades rail-to-rail input capability for higher bandwidth and faster settling, while OPA2835IDGKT sacrifices speed to achieve lower noise and offset - making LMH6619MAX/NOPB the optimal balance for cost-sensitive, wideband, single-supply ADC/DAC interface applications.

FAQ
What is the maximum operating supply voltage for LMH6619MAX/NOPB?
The LMH6619MAX/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. At 11 V, output swing remains rail-to-rail, and supply current increases to ~1.75 mA per channel.
Does LMH6619MAX/NOPB support true rail-to-rail input on a 3.3 V supply?
Yes, LMH6619MAX/NOPB supports rail-to-rail input on 3.3 V supply: its common-mode input range extends from −0.2 V to +3.5 V (i.e., 200 mV beyond both rails). This allows direct connection of sensors or DAC outputs referenced to ground or VDD without external level shifting.
What is the typical output drive capability of LMH6619MAX/NOPB into capacitive loads?
LMH6619MAX/NOPB drives up to 30 pF capacitive loads without external compensation while maintaining stability. For larger loads (e.g., >50 pF), a series isolation resistor (RISO) of 25–100 Ω is recommended - verified in TI's SNOSAV7E datasheet Figure 9 and application notes.
How does LMH6619MAX/NOPB perform in terms of crosstalk between channels?
LMH6619MAX/NOPB exhibits 80 dB crosstalk rejection at 5 MHz (VIN = 2 VPP), meaning a 2 VPP signal on Channel A induces only ~25 µV on Channel B output. This isolation enables simultaneous dual-channel acquisition in mixed-signal systems without inter-channel interference.
Is LMH6619MAX/NOPB qualified for automotive applications?
LMH6619MAX/NOPB is rated for −40°C to +125°C industrial temperature grade and meets JEDEC JESD22-A115-A (HBM) ESD spec of 2000 V, but it is not AEC-Q200 qualified. For automotive use, TI recommends the pin-compatible LMH6619QDGKRQ1 variant, which undergoes full automotive qualification testing.
