Product details
Overview
LM6144BIM/NOPB from Texas Instruments is a quad rail-to-rail input-output operational amplifier optimized for low-voltage, low-power precision signal conditioning. It delivers 17MHz gain-bandwidth, 30V/μs slew rate, 650μA per amplifier quiescent current, 107dB CMRR, and operates from 2.7V to 24V supply - enabling high-fidelity analog front-ends in battery-powered depth sounders and portable instrumentation.
For engineers reviewing the LM6144BIM/NOPB datasheet, LM6144BIM/NOPB pinout, LM6144BIM/NOPB application, or LM6144BIM/NOPB equivalent, key selection criteria include verified rail-to-rail I/O swing at 2.7V, guaranteed 17MHz GBW at 50kHz, thermal performance in SOIC-14 (82.48°C/W RθJA), and compatibility with single-supply ADC buffering and 3-op-amp instrumentation amplifier topologies.
Technical Context
The LM6144BIM/NOPB employs a patented dual-input-stage architecture combining NPN and PNP differential pairs to achieve true rail-to-rail input common-mode range (−0.25V to 5.25V at 5V supply) without external level-shifting. Its slew-boosted output stage enables 30V/μs transient response while maintaining stability into 100pF capacitive loads - critical for driving ADC inputs and multiplexed sensor interfaces.
Designed for operation across 2.7V–24V supplies, it maintains ≥10MHz GBW down to 2.7V and sustains >100dB open-loop gain (RL = 10kΩ) with <2.5mV max input offset voltage (B-grade, −40°C to 85°C). The device exhibits 87dB PSRR and 114dB CMRR at 24V supply, confirming robust rejection of supply and common-mode noise in mixed-signal systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 17MHz at 50kHz (typ); enables stable unity-gain buffer or 10× gain amplification up to ~1.7MHz. |
| Slew rate | 30V/μs (typ); supports fast settling of 10-bit+ signals without distortion in ADC driver applications. |
| Input offset voltage | 2.5mV max (B-grade, −40°C to 85°C); ensures ≤0.025% gain error in 100mV full-scale sensor interfaces. |
| Supply current per amplifier | 650μA (typ at 5V); allows four-channel operation at <2.6mA total - ideal for multi-sensor battery nodes. |
| Common-mode input range | −0.25V to 5.25V at 5V supply; accepts inputs beyond rails, eliminating need for external biasing in single-supply designs. |
| Output voltage swing | Within 30mV of rails (RL = 100kΩ); preserves >99% dynamic range at low supply voltages like 3.3V. |
| CMRR | 107dB (typ at 5V); rejects >99.999% of common-mode interference in noisy industrial environments. |
Pinout & Package
LM6144BIM/NOPB is housed in a 14-pin SOIC package (body size 8.65mm × 3.91mm) with standard quad op-amp pinout compatible with industry layout practices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 12 | Inverting input (−) | High-impedance node (126MΩ) accepting rail-to-rail common-mode signals; requires no external bias network. |
| 2, 6, 10, 13 | Non-inverting input (+) | Same rail-to-rail CMVR as inverting input; enables true differential sensing without level shifters. |
| 3, 7, 11, 14 | Output | Rail-to-rail swing (30mV from rails, RL = 100kΩ); drives ADC inputs or downstream buffers directly. |
| 4 | V− (negative supply) | Ground reference for single-supply operation; supports operation down to 0V (no negative rail required). |
| 13 | V+ (positive supply) | Accepts 2.7V–24V; internal regulation ensures consistent GBW and slew rate across full voltage range. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input CMVR | Extends 0.25V beyond supply rails - eliminates input clamping diodes and external bias resistors in single-supply circuits. |
| Slew-boosted output stage | Delivers 30V/μs without external compensation - stabilizes against 100pF capacitive loads typical of PCB traces and ADC inputs. |
| Low quiescent current | 650μA per amplifier at 5V enables four-channel signal conditioning in sub-3mA battery systems (e.g., handheld meters). |
| High CMRR & PSRR | 107dB CMRR and 87dB PSRR ensure minimal error from power rail ripple or ground bounce in mixed-signal PCBs. |
| Wide supply range | 2.7V–24V operation supports both coin-cell-powered sensors and industrial 24V PLC analog modules with one BOM. |

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 (600μA per amp), same SOIC-14 package. | Less suitable for >1MHz ADC buffering or fast pulse amplification. | Prefer TLV2464IDR only when ultra-low power (<2.4mA total) outweighs bandwidth needs. |
| OPA4340UA | Higher precision (125μV VOS max), lower noise (8nV/√Hz), but limited 5.5V max supply. | Not viable for 12V/24V industrial sensor interfaces requiring wide supply range. | Choose OPA4340UA only for low-voltage (<6V), high-accuracy applications where supply headroom is constrained. |
Compared with TLV2464IDR and OPA4340UA, LM6144BIM/NOPB uniquely balances 17MHz bandwidth, 2.7–24V operation, and rail-to-rail I/O in a single SOIC-14 package - making it the only option supporting both battery-powered portables and wide-supply industrial signal chains without design compromise.

FAQ
What is the maximum operating supply voltage for LM6144BIM/NOPB?
The absolute maximum supply voltage for LM6144BIM/NOPB is 33V, with recommended operation from 2.7V to 32V. At 24V supply, it maintains 18MHz GBW and 114dB CMRR - enabling use in industrial 24V analog modules without derating. Exceeding 33V risks permanent damage per TI's Absolute Maximum Ratings table.
Does LM6144BIM/NOPB support rail-to-rail input at 2.7V supply?
Yes, LM6144BIM/NOPB supports rail-to-rail input at 2.7V supply, with a common-mode input voltage range of 0V to 2.7V (typical). This eliminates the need for external bias networks in low-voltage sensor interfaces, preserving signal fidelity and simplifying PCB layout for battery-powered devices.
What is the typical output voltage swing for LM6144BIM/NOPB driving a 10kΩ load?
At 5V supply and 25°C, LM6144BIM/NOPB delivers a typical output swing within 40mV of the positive rail and 50mV of the negative rail into a 10kΩ load. This >98% rail utilization ensures maximum dynamic range for 12-bit ADC interfacing and low-voltage signal chain designs.
Is LM6144BIM/NOPB stable when driving capacitive loads?
Yes, LM6144BIM/NOPB features a slew-boosted output stage that ensures stability into ≥100pF capacitive loads without external compensation - a key requirement for driving ADC inputs, long PCB traces, or multiplexed sensor arrays. This capability is verified in TI's Typical Characteristics (Figure 5-19–5-20).
What grade does the 'B' suffix indicate in LM6144BIM/NOPB?
The 'B' in LM6144BIM/NOPB denotes the B-grade version, specifying a maximum input offset voltage of 2.5mV at 25°C and 3.3mV over −40°C to 85°C. This grade provides tighter DC accuracy than the A-grade (1mV/2.2mV) while maintaining identical AC performance, making it optimal for cost-sensitive precision applications.
