Product details
Overview
LM6154BCM-TI from Texas Instruments is a quad rail-to-rail input/output operational amplifier optimized for high-speed, low-power portable instrumentation and signal conditioning. 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-ideal for ADC buffering in battery-powered data acquisition systems.
For engineers reviewing the LM6154BCM-TI datasheet, LM6154BCM-TI pinout, LM6154BCM-TI application, or LM6154BCM-TI equivalent, key selection considerations include its wide supply range (2.7–24 V), rail-to-rail I/O capability across temperature (0°C to +70°C), 1.1 µs settling time to 0.01%, and guaranteed performance at both low (2.7 V) and high (24 V) supply rails-critical for multi-voltage system design and precision analog front-ends.
Technical Context
The LM6154BCM-TI employs a patented input stage with phase reversal prevention and dynamic slew-rate enhancement: slew rate increases with input differential voltage (e.g., from 5 V/µs small-signal to 45 V/µs large-signal), improving transient response and stability into capacitive loads. Its architecture enables stable operation at closed-loop gains ≥2 without external compensation in most configurations.
It features true rail-to-rail input common-mode range (−0.25 V to 24.25 V at 24 V supply) and rail-to-rail output swing (within 10 mV of rails), maximizing dynamic range in single-supply systems. Amplifier-to-amplifier isolation exceeds 125 dB, minimizing crosstalk in multi-channel signal paths such as simultaneous-sampling ADC drivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 75 MHz @ 100 kHz - supports stable unity-gain and low-noise gain-of-10 amplification up to ~7.5 MHz. |
| Slew Rate (Large Signal) | 45 V/µs - enables clean 2 V step response in ≤1.1 µs with <0.01% error, critical for fast-settling ADC buffers. |

| PSRR / CMRR | 91 dB / 84 dB - rejects power supply noise and common-mode interference in noisy industrial environments. |
| Operating Temperature | 0°C to +70°C - qualified for commercial-grade embedded systems including barcode scanners and portable test gear. |
Pinout & Package
LM6154BCM-TI is housed in a 14-pin SOIC (D package) with 8.636 mm × 3.912 mm body size and 1.75 mm max height. Pin 1 is marked by a beveled corner or dot; the device uses standard SOIC lead pitch (1.27 mm) and JEDEC MS-012 AA outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | OUT A/B/C/D | Amplifier outputs - each drives 10 kΩ load to rail with <10 mV headroom; stable into 470 pF. |
| 2, 6, 9, 13 | −IN A/B/C/D | Inverting inputs - accept signals beyond supply rails; enable active filtering and precision inverting gain stages. |
| 3, 5, 10, 12 | +IN A/B/C/D | Non-inverting inputs - support rail-to-rail common-mode input; used for unity-gain buffers and sensor references. |
| 4 | V− | Negative supply terminal - connects to ground in single-supply mode; supports split supplies down to ±1.35 V. |
| 11 | V+ | Positive supply terminal - accepts 2.7 V to 24 V; PSRR >91 dB ensures immunity to supply ripple. |
Key Features
| Feature | Design Value |

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 VOS (1.6 mV max vs. 7 mV max for LM6154BCM-TI). | Better for DC-precision, low-power sensor nodes; insufficient for >100 kHz signal conditioning. | Select TLV2464IDR when offset and quiescent current dominate over bandwidth and slew rate. |
| OPA4340UA | Higher precision (VOS = 0.5 mV max), lower noise (8 nV/√Hz), but lower GBW (5.5 MHz) and no dynamic slew enhancement. | Preferred for high-resolution weigh scales and medical biosensors; lacks speed for fast ADC buffering. | Choose OPA4340UA for sub-16-bit DC-critical applications where 75 MHz GBW is unnecessary. |
Compared with TLV2464IDR and OPA4340UA, LM6154BCM-TI uniquely balances high speed (75 MHz), low power (1.4 mA), and rail-to-rail I/O in a single quad package-making it optimal for battery-powered instrumentation needing both bandwidth and efficiency.

FAQ
What is the maximum capacitive load LM6154BCM-TI can drive without oscillation?
The LM6154BCM-TI is characterized to drive up to 470 pF capacitive loads stably at closed-loop gains of 2 or higher, thanks to its internal phase-shift compensation circuit. This eliminates need for external isolation resistors in ADC driver and cable-driving applications. Performance remains stable across 2.7 V to 24 V supply range, though bandwidth reduction scales with load capacitance-verified in TI's Figure 17 (Voltage Swing vs. Frequency) and Application Note SNOS752E Section 7.
Does LM6154BCM-TI support true rail-to-rail input at 24 V supply?
Yes. The LM6154BCM-TI guarantees input common-mode voltage range from −0.25 V to 24.25 V when operated at V+ = 24 V and V− = 0 V, per Section 6.5 DC Electrical Characteristics. This "beyond-the-rails" input capability allows direct interfacing with sensors or DACs that swing outside the supply domain-no external level-shifting required. Verified across temperature (0°C to +70°C) and process corners.
What is the typical settling time of LM6154BCM-TI for a 2 V step?
The LM6154BCM-TI achieves 1.1 µs settling time to 0.01% for a 2 V step under standard test conditions (V+ = 5 V, RL = 10 kΩ, VCM = VO = V+/2), as specified in Section 6.6 AC Electrical Characteristics. This value holds across the full operating temperature range and is enabled by its dynamic slew-rate architecture-large-signal slew rate reaches 45 V/µs, preventing tailing in fast transitions.
Is LM6154BCM-TI RoHS compliant and lead-free?
Yes. The LM6154BCM-TI/NOPB variant is RoHS-compliant and lead-free, with Green (RoHS & no Sb/Br) finish and SN (matte tin) lead termination. It meets JEDEC MSL Level-1 (260°C peak reflow) and is qualified for standard Pb-free soldering processes. This is confirmed in TI's Package Option Addendum (6-Feb-2020), where LM6154BCM/NOPB and LM6154BCMX/NOPB are marked ACTIVE with full eco-plan documentation.
How does the dynamic slew-rate enhancement in LM6154BCM-TI improve system stability?
The LM6154BCM-TI's input stage increases slew rate proportionally with input differential voltage-rising from 5 V/µs (small-signal) to 45 V/µs (large-signal). This reduces phase lag during fast transients, counteracting the destabilizing effect of capacitive loads. As a result, the amplifier maintains >45° phase margin into 470 pF loads without external compensation-unlike conventional op amps that require series isolation resistors or complex feedback networks.
