Product details
Overview
LM6154BCM from Texas Instruments is a quad rail-to-rail input/output operational amplifier optimized for low-voltage, high-speed applications. It delivers 75 MHz gain-bandwidth at 100 kHz, 45 V/µs large-signal slew rate, and rail-to-rail output swing (0.01 V to 4.99 V at 5 V supply), with only 1.4 mA per amplifier supply current. It operates across 2.7 V to 24 V supplies and supports portable instrumentation, ADC buffering, and barcode scanning systems.
For engineers reviewing the LM6154BCM datasheet, LM6154BCM pinout, LM6154BCM application, or LM6154BCM equivalent, this page provides verified technical context, SOIC-14 package mapping, confirmed rail-to-rail I/O behavior, real-world settling time (1.1 µs to 0.01%), and validated alternative options for dual-supply or battery-powered signal conditioning designs.
Technical Context
The LM6154BCM employs a patented input stage that enables greater-than-rail-to-rail common-mode input range (−0.25 V to 24.25 V) and dynamically increases slew rate with input differential voltage-reaching >30 V/µs for large signals. Its architecture inherently suppresses phase reversal and maintains stability driving capacitive loads up to 470 pF at gains ≥2.
This quad op amp features unity-gain stable operation, 84 dB CMRR and 91 dB PSRR at 5 V, and wide supply flexibility (2.7–24 V). Its low 1.4 mA/amplifier quiescent current enables use in power-constrained systems without sacrificing 75 MHz bandwidth or 1.1 µs settling performance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 75 MHz @ 100 kHz - enables stable closed-loop operation up to ~7.5 MHz at gain = 10 |
| Slew Rate (Large Signal) | 45 V/µs - supports fast transient response in pulse amplification and active filter stages |
| Input CMVR | −0.25 V to 24.25 V - accepts inputs beyond rails, eliminating level-shifting in mixed-supply systems |
| Rail-to-Rail Output Swing | 0.01 V to 4.99 V (at 5 V) - maximizes dynamic range and ADC utilization in low-voltage data acquisition |
| Supply Current per Amplifier | 1.4 mA - allows four-channel amplification within <5.6 mA total, critical for battery life in portable devices |
| Settling Time | 1.1 µs to 0.01% for 2 V step - ensures accurate sampling in multiplexed ADC front-ends |
| PSRR / CMRR | 91 dB / 84 dB - rejects supply noise and common-mode interference in noisy industrial environments |
Pinout & Package
LM6154BCM is housed in a 14-pin SOIC (D14A) package measuring 8.636 mm × 3.912 mm, with 1.27 mm lead pitch and 1.75 mm max height. The package is RoHS-compliant, green (no Sb/Br), and rated MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | OUT A/B/C/D | Amplifier outputs - each drives rail-to-rail loads up to 2 kΩ with <0.12 V headroom |
| 2, 6, 9, 13 | −IN A/B/C/D | Inverting inputs - accept signals beyond supply rails; require feedback network for closed-loop gain |
| 3, 5, 10, 12 | +IN A/B/C/D | Non-inverting inputs - support true rail-to-rail common-mode range and high-impedance sensing |
| 4 | V− | Negative supply terminal - connects to ground (single-supply) or negative rail (dual-supply) |
| 11 | V+ | Positive supply terminal - supports 2.7 V to 24 V operation; decoupling capacitor required |
Key Features
| Feature | Design Value |
|---|---|
| Dynamic Slew Rate Enhancement | Increases from 5 V/µs (small signal) to >45 V/µs (large signal), improving transient fidelity without external compensation |
| Capacitive Load Drive Stability | Stable with ≥470 pF loads at gain ≥2 - eliminates need for isolation resistors in sensor interface or DAC output stages |
| Rail-to-Rail Input Beyond Rails | Accepts −0.25 V to +24.25 V inputs on 24 V supply - removes input clamping diodes and level-shifters in mixed-voltage systems |
| Low-Power High-Speed Operation | 75 MHz GBW at only 1.4 mA/amplifier - enables multi-channel analog signal processing in energy-constrained IoT edge nodes |
| Fast Settling with Precision | 1.1 µs to 0.01% for 2 V step - meets timing budgets in 1 MSPS+ SAR ADC buffer applications |

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), higher supply current (650 µA/amplifier), no dynamic slew enhancement | Better DC precision (0.3 mV VOS), suited for low-frequency sensor amps-not high-speed pulse or wideband apps | Select when ultra-low offset and drift outweigh speed/power needs; not suitable for >1 MHz signal paths |
| OPA4340UA | Higher GBW (5.5 MHz), lower noise (8 nV/√Hz), but fixed 0.5 V/µs slew rate and narrower CMVR (to rails only) | Optimized for precision audio and medical instrumentation; lacks rail-exceeding input and dynamic slew | Prefer for low-noise, low-distortion audio buffering where input voltage stays within supply bounds |
Compared with TLV2464IDR and OPA4340UA, the LM6154BCM uniquely combines rail-exceeding input, dynamic slew rate, and 75 MHz bandwidth at sub-2 mA/amplifier-making it irreplaceable in portable high-speed signal chains where both speed and power efficiency are non-negotiable.

FAQ
What is the operating temperature range for the LM6154BCM?
The LM6154BCM is specified for operation from 0°C to +70°C ambient temperature. This commercial-grade rating aligns with its intended use in portable instrumentation and industrial control interfaces where environmental extremes are managed externally. The device's thermal resistance (RθJA = 126°C/W) supports reliable operation within this range when mounted on standard FR-4 PCBs with adequate copper area.
Does the LM6154BCM support single-supply operation?
Yes, the LM6154BCM fully supports single-supply operation from 2.7 V to 24 V. Its rail-to-rail input extends 0.25 V beyond both supply rails, and its output swings to within 10 mV of each rail-enabling direct interfacing with unipolar sensors and ADCs without level-shifting circuitry. This capability is confirmed across all supply voltages in the datasheet's electrical characteristics tables.
Can the LM6154BCM drive a 1000 pF capacitive load?
No-the LM6154BCM is characterized for stable operation with up to 470 pF capacitive loads at gains ≥2. Driving 1000 pF may cause excessive overshoot, ringing, or instability depending on layout and gain configuration. For larger loads, external isolation resistors or gain adjustment per TI's Application and Implementation section (Figure 26) are required to maintain phase margin.
What is the typical input offset voltage for the LM6154BCM at 5 V supply?
The typical input offset voltage for the LM6154BCM at 5 V supply is 0.54 mV, with a maximum limit of 5 mV over temperature. This value is explicitly listed in the "5.0 V DC Electrical Characteristics" table (Section 6.5) of the SNOS752E datasheet and applies to the BC grade version, which matches the LM6154BCM ordering suffix.
Is the LM6154BCM pin-compatible with other quad op amps like the LM324?
No-the LM6154BCM uses a 14-pin SOIC package with a unique pinout optimized for rail-to-rail I/O and quad-channel independence. It is not pin-compatible with legacy quad op amps such as the LM324 (which uses a different pin assignment and lacks rail-to-rail capability). Direct replacement requires PCB layout revision and validation of signal routing and decoupling.
