Product details
Overview
LM6154BCMX from Texas Instruments is a quad rail-to-rail input/output operational amplifier optimized for high-speed, low-power portable and instrumentation applications. It delivers 75 MHz gain-bandwidth, 45 V/µs large-signal slew rate, and rail-to-rail output swing (0.01 V to 4.99 V at 5 V supply) while consuming only 1.4 mA per amplifier. It operates from 2.7 V to 24 V and supports capacitive loads up to 470 pF without oscillation.
For engineers reviewing the LM6154BCMX datasheet, LM6154BCMX pinout, LM6154BCMX application, or LM6154BCMX equivalent, key selection considerations include its wide supply range, input CMVR extending beyond rails (−0.25 V to 24.25 V), fast 1.1 µs settling time to 0.01%, and guaranteed performance across 0°C to +70°C ambient.
Technical Context
The LM6154BCMX employs a patented input stage with phase reversal prevention and slew-rate acceleration-its slew rate increases with input differential voltage, enabling stable operation into large capacitive loads while maintaining signal fidelity. This architecture eliminates typical op-amp instability when driving ADC input buffers or long cables.
It features true rail-to-rail input common-mode range (exceeding both supply rails by ±0.25 V) and rail-to-rail output swing (within 10 mV of each rail), maximizing dynamic range in low-voltage systems. Its 84 dB CMRR and 91 dB PSRR ensure robust performance in noisy industrial or mixed-signal environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 75 MHz @ 100 kHz - enables stable unity-gain buffer or G = 10 amplification up to ~7.5 MHz. |
| Slew Rate (Large Signal) | 45 V/µs - supports full-scale 2 V step in ≤44 ns, critical for pulse conditioning and fast-settling data acquisition. |
| Supply Current per Amplifier | 1.4 mA - allows four-channel operation at <5.6 mA total, ideal for battery-powered handheld instruments. |
| Input CMVR | −0.25 V to 24.25 V - accepts signals beyond rails, eliminating level-shifting needs in sensor front-ends. |
| Rail-to-Rail Output Swing | 0.01 V to 4.99 V @ 5 V supply - delivers >99% of available voltage range, maximizing SNR in ADC driver stages. |
| Settling Time | 1.1 µs to 0.01% for 2 V step - meets timing budgets in 1 MSPS+ SAR ADC systems with minimal dead time. |
| PSRR / CMRR | 91 dB / 84 dB - rejects power supply ripple and common-mode noise in precision analog signal chains. |

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 (6.4 MHz), lower supply current (600 µA), but tighter offset (2 mV max vs. 5 mV max for LM6154BCMX). | Better for ultra-low-power, DC-precision apps; unsuitable for >100 kHz signal conditioning due to bandwidth limit. | Select TLV2464IDR when power budget <2.5 mA total and bandwidth <100 kHz suffices. |
| OPA4340UA | Higher precision (125 µV max VOS), lower noise (7 nV/√Hz), but lower slew rate (0.6 V/µs) and GBW (5.5 MHz). | Optimized for precision DC/low-frequency measurement; cannot support fast-settling or wideband AC-coupled paths. | Choose OPA4340UA for high-resolution weigh scales or medical ECG front-ends where speed is secondary to offset/noise. |
Compared with TLV2464IDR and OPA4340UA, LM6154BCMX uniquely balances high speed (75 MHz GBW), low power (1.4 mA), and rail-to-rail operation-making it the only option among the three suitable for portable instrumentation requiring both bandwidth and battery efficiency.

FAQ
What is the operating temperature range for LM6154BCMX?
The LM6154BCMX is specified for operation from 0°C to +70°C ambient temperature. This commercial-grade range aligns with its target applications in portable test equipment and industrial control modules where environmental extremes are managed externally. The device's thermal resistance (RθJA = 126°C/W) ensures safe junction temperatures under typical PCB layouts with moderate copper area.
Does LM6154BCMX support single-supply operation?
Yes, LM6154BCMX fully supports single-supply operation from 2.7 V to 24 V. Its input common-mode voltage range extends from −0.25 V to (V+ + 0.25 V), allowing inputs below ground or above V+, and its rail-to-rail output swings within 10 mV of both rails-enabling true single-supply signal conditioning without level-shifting circuitry.
Can LM6154BCMX drive heavy capacitive loads without compensation?
Yes, LM6154BCMX is designed to remain stable with capacitive loads up to 470 pF at gains ≥2 without external compensation. Its internal slew-rate acceleration architecture actively counteracts phase lag caused by load capacitance, eliminating oscillation risk in ADC buffer or cable-driving configurations where traditional op-amps require series isolation resistors.
What is the maximum supply voltage rating for LM6154BCMX?
The absolute maximum supply voltage for LM6154BCMX is 35 V (V+ − V−), with recommended operation from 2.7 V to 24 V. At 24 V supply, it delivers 23.91 V minimum output swing into 10 kΩ, supporting industrial 24 V systems while maintaining 1.6 mA/amplifier supply current-enabling direct integration into PLC analog I/O modules.
How does the slew rate of LM6154BCMX vary with input signal amplitude?
LM6154BCMX features a patented input stage where slew rate increases with input differential voltage: small-signal slew rate is 5 V/µs, rising to 45 V/µs for large signals. This behavior reduces phase lag into capacitive loads and improves transient response-e.g., a 2 V step settles in 1.1 µs, while a 0.1 V step settles faster due to lower required dV/dt.
