Product details
Overview
LM6144BIN/NOPB from Texas Instruments is a quad rail-to-rail input-output operational amplifier optimized for low-voltage, battery-powered instrumentation. It delivers 17MHz gain-bandwidth at 50kHz, 30V/μs slew rate, 650μA/amplifier quiescent current, ±4000V HBM ESD rating, and operates from 2.7V to 24V supply. It enables high-fidelity signal conditioning in depth sounders and barcode scanners.
For engineers reviewing the LM6144BIN/NOPB datasheet, LM6144BIN/NOPB pinout, LM6144BIN/NOPB application, or LM6144BIN/NOPB equivalent, key selection criteria include rail-to-rail CMVR (−0.25V to 5.25V @ 5V), output swing within 30mV of rails (RL = 100kΩ), 107dB CMRR, 87dB PSRR, and SOIC-14 package compatibility with space-constrained PCB layouts.
Technical Context
The LM6144BIN/NOPB employs a patented dual-input-stage architecture-combining NPN and PNP differential pairs-to achieve true rail-to-rail input common-mode range exceeding supply rails by ±0.25V. Its slew-boosted output stage enables 30V/μs transient response while maintaining stability into 100pF capacitive loads without external compensation.
This architecture supports single-supply operation down to 2.7V with full dynamic range utilization: open-loop gain exceeds 100 V/mV (RL = 10kΩ), input bias current remains ≤300nA across −40°C to 85°C, and input voltage noise is 16nV/√Hz at 1kHz-enabling precision DC-coupled amplification in portable analog front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 17MHz at 50kHz - enables stable unity-gain buffer configurations up to ~10MHz with minimal phase margin degradation |
| Slew rate | 30V/μs - supports fast settling of 10-bit ADC input steps (<100ns) without slewing distortion |
| Supply current per amplifier | 650μA - allows four-channel operation on 10mA total budget, extending battery life in handheld instruments |
| Input CMVR | −0.25V to 5.25V @ VS = 5V - eliminates level-shifting circuitry when interfacing with 0–5V sensors or DACs |
| Output swing (RL = 100kΩ) | Within 30mV of positive rail, 45mV of negative rail - preserves >99% of available dynamic range at low supply voltages |
| CMRR | 107dB - rejects >99.999% of common-mode interference in noisy industrial sensor nodes |
| PSRR | 87dB - maintains DC accuracy despite ±100mV supply ripple in battery-powered systems |
Pinout & Package
LM6144BIN/NOPB is housed in a 14-pin SOIC (D) package measuring 8.65mm × 3.91mm, with standard JEDEC MS-012AC footprint and 1.27mm pitch. Thermal resistance RθJA is 82.48°C/W, supporting continuous operation at 85°C ambient without forced airflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 12 | Inverting input (−) | Accepts differential signals referenced to ground or mid-supply; supports rail-to-rail common-mode range |
| 2, 6, 10, 13 | Non-inverting input (+) | Enables unity-gain follower, difference amp, or active filter topologies with full input voltage range |
| 3, 7, 11, 14 | Output | Drives 100kΩ loads to within 30mV of rails; stable into ≥100pF capacitive loads without isolation resistor |
| 4 | V− (negative supply) | Ground reference for single-supply operation or negative rail in split-supply configurations |
| 11 | V+ (positive supply) | Accepts 2.7V–24V; internal regulation ensures consistent biasing across full voltage range |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input CMVR | Extends beyond supply rails (−0.25V to +5.25V @ 5V), eliminating input clamping diodes and external level shifters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IDR | Lower GBW (6.4MHz), higher IQ (550μA/channel), same SOIC-14 package | Optimized for ultra-low-power sensor interfaces where bandwidth <5MHz suffices | Select TLV2464IDR only if system bandwidth requirement is ≤5MHz and supply current must be minimized below 550μA/channel |
| OPA4340UA | Higher precision (50μV VOS max), lower noise (11nV/√Hz), but limited 5.5V max supply | Suitable for precision medical instrumentation requiring sub-100μV offset and 3.3V operation | Choose OPA4340UA when offset voltage and noise dominate over supply voltage range and bandwidth needs |
Compared with TLV2464IDR and OPA4340UA, LM6144BIN/NOPB uniquely balances 17MHz bandwidth, 30V/μs slew rate, and 2.7–24V operation-making it the only option among the three capable of driving wideband ADCs from 3.3V to 24V supplies without performance trade-offs.

FAQ
What is the maximum supply voltage for LM6144BIN/NOPB?
The absolute maximum supply voltage for LM6144BIN/NOPB is 33V, as specified in the Absolute Maximum Ratings table. Operation above this voltage risks permanent damage. The recommended operating range is 2.7V to 32V, with optimal performance observed between 5V and 12V for most instrumentation applications. LM6144BIN/NOPB maintains rail-to-rail functionality and 17MHz GBW across this full range.
Does LM6144BIN/NOPB support true rail-to-rail input common-mode range?
Yes, LM6144BIN/NOPB supports a true rail-to-rail input common-mode voltage range extending beyond the supply rails: −0.25V to 5.25V when VS = 5V. This is achieved via complementary NPN/PNP input stages, eliminating the need for external level-shifting circuitry when interfacing with 0V-referenced sensors or DAC outputs. LM6144BIN/NOPB maintains this extended CMVR across its entire 2.7V–24V supply range.
What is the typical output voltage swing for LM6144BIN/NOPB at 5V supply?
At VS = 5V and RL = 100kΩ, LM6144BIN/NOPB delivers a typical output swing within 30mV of the positive rail and 45mV of the negative rail-i.e., 0.045V to 4.97V. This rail-to-rail capability preserves >99% of available dynamic range, critical for maximizing resolution in 12-bit ADC interfaces. LM6144BIN/NOPB maintains this performance across −40°C to 85°C ambient temperature.
Can LM6144BIN/NOPB drive capacitive loads without oscillation?
Yes, LM6144BIN/NOPB features a slew-boosted output stage that provides stable operation into ≥100pF capacitive loads without requiring external isolation resistors. This is confirmed in the datasheet's "Capacitive Load Driving" section and typical characteristics (Figure 5-19–5-20). LM6144BIN/NOPB maintains ≥36° phase margin under these conditions, making it suitable for driving ADC sample-and-hold inputs and long PCB traces directly.
What is the ESD rating for LM6144BIN/NOPB?
LM6144BIN/NOPB has a Human-Body Model (HBM) ESD rating of ±4000V and a Charged-Device Model (CDM) rating of ±1500V, per ANSI/ESDA/JEDEC JS-001 and JS-002 standards. These ratings reflect robust on-chip protection diodes and layout hardening, enabling safe handling in standard ESD-controlled environments without additional external protection. LM6144BIN/NOPB meets industrial-grade ESD immunity requirements for field-deployable instrumentation.
