Product details
Overview
LM6144BIN 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/amplifier quiescent current, rail-to-rail CMVR (−0.25V to 5.25V at 5V supply), and 107dB CMRR - enabling high-fidelity analog front-ends in battery-powered instrumentation such as depth sounders and barcode scanners.
For engineers reviewing the LM6144BIN datasheet, LM6144BIN pinout, LM6144BIN application, or LM6144BIN equivalent, key selection considerations include its guaranteed rail-to-rail operation down to 2.7V supply, thermal performance in PDIP-14 (RθJA = 81°C/W), output swing within 30mV of rails (100kΩ load), and compatibility with single-supply A/D converter buffering and 3-op-amp instrumentation amplifier topologies.
Technical Context
The LM6144BIN employs a patented dual-input-stage architecture (NPN + PNP) to achieve true rail-to-rail input common-mode range exceeding the supply rails by ±0.25V, eliminating input clipping concerns in single-supply systems. Its slew-boosted output stage enables 30V/μs transient response while maintaining stability into capacitive loads up to 1000pF without external compensation.
Designed for wide-supply operation (2.7V to 24V), it maintains ≥10MHz GBW across voltage extremes and exhibits 87dB PSRR and 107dB CMRR at 5V - critical for rejecting supply noise and common-mode interference in portable sensing applications where power efficiency and dynamic range are co-constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 17MHz at 50kHz (typ); supports stable closed-loop gain ≥100 at 100kHz in sensor signal chains. |
| Slew Rate | 30V/μs (typ); enables accurate reproduction of fast transients in ultrasonic echo processing (e.g., fish finders). |
| Supply Current | 650μA per amplifier (typ at 5V); allows four-channel amplification on <3mA total, extending battery life in portable instruments. |
| Input CMVR | −0.25V to 5.25V at 5V supply; accepts signals beyond rails, simplifying level-shifting in single-supply ADC drivers. |
| Output Swing | Within 30mV of positive rail and 45mV of negative rail (100kΩ load); maximizes usable dynamic range at low supply voltages. |
| CMRR | 107dB (typ); rejects common-mode noise from shared ground paths in multi-sensor industrial modules. |
| PSRR | 87dB (typ); suppresses ripple and switching noise from DC/DC converters powering mixed-signal PCBs. |
Pinout & Package
LM6144BIN is housed in a 14-pin plastic dual in-line package (PDIP) with 19.177mm × 6.35mm body size and 0.300-inch lead pitch. The package is through-hole mountable and RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | Inverting Input (−) | High-impedance differential input node for each of four op-amps; accepts signals from −0.25V to V+ + 0.25V. |
| 2, 6, 10, 14 | Non-inverting Input (+) | High-impedance differential input node; enables unity-gain buffer or difference amplifier configurations. |
| 3, 7, 11, 12 | Output | Rail-to-rail output capable of sourcing/sinking ≥6mA; drives 10kΩ loads with <140mV headroom to rails. |
| 4 | V− (Ground/–VS) | Negative supply terminal; referenced to system ground in single-supply operation (0V minimum). |
| 14 | V+ (+VS) | Positive supply terminal; supports 2.7V to 24V operation; decoupling capacitor required near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input CMVR | Extends beyond supply rails (−0.25V to V+ + 0.25V), eliminating need for input biasing resistors in single-supply designs. |

| Low quiescent current | 650μA per amplifier at 5V allows full quad operation under 3mA, supporting >100-hour runtime on AA batteries. |
| High open-loop gain | 108dB (at RL = 10kΩ) ensures <0.01% gain error in precision instrumentation amplifier configurations. |
| Enhanced PSRR/CMRR | 87dB PSRR and 107dB CMRR maintain signal integrity in noisy environments like motor-driven depth sounder housings. |

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 |
|---|---|---|---|
| TLC27L4CD | Lower GBW (890kHz), higher input offset (5mV max), but lower IQ (190μA/amplifier) and wider temp range (−55°C to 125°C). | Better suited for ultra-low-power, low-speed sensor interfaces where bandwidth <1MHz suffices. | Select TLC27L4CD only when supply current is primary constraint and signal bandwidth ≤100kHz. |
| OPA4340UA | Higher GBW (5.5MHz), lower noise (12nV/√Hz), but higher IQ (750μA/amplifier) and narrower CMVR (to rails only, not beyond). | Preferred for precision medical instrumentation requiring low noise and high DC accuracy over extended temperature ranges. | Choose OPA4340UA when noise performance and DC precision outweigh rail-exceeding input range requirements. |
Compared with TLC27L4CD and OPA4340UA, LM6144BIN uniquely balances 17MHz bandwidth, rail-exceeding input range, and sub-1mA total quad current - making it optimal for battery-powered ultrasonic and optical sensing where speed, dynamic range, and power co-constrain design.

FAQ
What is the maximum supply voltage rating for LM6144BIN?
The absolute maximum supply voltage for LM6144BIN is 33V, as specified in the Absolute Maximum Ratings table. Operation above this voltage risks permanent damage. Recommended operating range remains 2.7V to 24V, with electrical characteristics fully characterized across that span. Always observe derating guidelines for reliability in high-temperature environments.
Does LM6144BIN support true rail-to-rail input beyond the supply rails?
Yes, LM6144BIN supports common-mode input voltage from (V−) − 0.25V to (V+) + 0.25V at 5V supply - confirmed in the Electrical Characteristics table (VCM = −0.25V to 5.25V). This "beyond-the-rails" input range eliminates input clamping concerns in single-supply systems and simplifies interface design with sensors or DACs operating near supply limits.
What is the typical output voltage swing for LM6144BIN driving a 10kΩ load?
At 5V supply and 25°C, LM6144BIN delivers typical output swing within 40mV of the positive rail and 50mV of the negative rail into a 10kΩ load - per Electrical Characteristics section 5.6. This rail-to-rail capability ensures >4.9V peak-to-peak dynamic range in 5V systems, critical for maximizing ADC utilization in portable instrumentation.
Can LM6144BIN drive capacitive loads without external compensation?
Yes, LM6144BIN is explicitly characterized to drive ≥1000pF loads stably without oscillation, as noted in the Description and Application sections. Its slew-boosted architecture and internal compensation enable direct connection to ADC input capacitors, piezoelectric transducers, and long PCB traces - reducing bill-of-materials and layout complexity in ultrasonic and sensor interface designs.
Is LM6144BIN pin-compatible with other quad op amps in PDIP-14 packages?
No documented pin-compatible replacements exist for LM6144BIN in PDIP-14. Its pinout (dual inverting/non-inverting inputs per amplifier, shared supplies) differs from industry-standard quad op amp layouts like LM324 or TL084. Substitution requires schematic and layout revision. Always verify functional equivalence and test stability under actual load conditions before replacement.
