Product details
Overview
LM6152BCMX from Texas Instruments is a dual rail-to-rail input/output operational amplifier optimized for high-speed, low-power portable 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), operating from 2.7 V to 24 V with only 1.4 mA per amplifier supply current. It is used in battery-powered instrumentation requiring wide dynamic range and fast settling.
For engineers reviewing the LM6152BCMX datasheet, LM6152BCMX pinout, LM6152BCMX application, or LM6152BCMX equivalent, key selection considerations include its rail-to-rail I/O capability across wide supply voltages, input voltage range extending beyond rails (−0.25 V to 5.25 V at 5 V), fast 1.1 µs settling time to 0.01%, and robust capacitive load drive up to 470 pF without oscillation.
Technical Context
The LM6152BCMX employs a patented input stage that enables greater-than-rail-to-rail common-mode input range (−0.25 V to 5.25 V at 5 V) and dynamically increases slew rate with input differential voltage-reaching 45 V/µs for large signals. This architecture improves phase margin when driving capacitive loads and reduces output lag under transient conditions.
Its unity-gain-stable design supports closed-loop gains ≥1 in both inverting and non-inverting configurations. Compensation is simplified: a 6.8 pF capacitor across a 10 kΩ feedback resistor achieves ~2 MHz bandwidth at gain = −10 with 10% overshoot when sourcing 5 V supply; no compensation needed for gains ≥100.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Input CMVR | −0.25 V to 5.25 V @ VS = 5 V - accepts inputs 0.25 V below ground or 0.25 V above V+, eliminating level-shifting in single-supply sensor interfaces |
| Rail-to-Rail Output Swing | 0.01 V to 4.99 V @ RL = 100 kΩ - preserves >99% of 5 V supply dynamic range, maximizing SNR in low-voltage data acquisition |
| Supply Current per Amplifier | 1.4 mA @ 5 V - enables dual-channel high-speed amplification in space-constrained, battery-operated systems with <2.8 mA total quiescent draw |
| Settling Time | 1.1 µs to 0.01% for 2 V step - meets timing budgets for 1 MSPS+ SAR ADC buffering without cycle loss |
| PSRR / CMRR | 91 dB / 84 dB - rejects power rail noise and common-mode interference in mixed-signal PCB layouts with shared analog/digital supplies |
Pinout & Package
LM6152BCMX is housed in an 8-pin SOIC (D08A) package measuring 4.902 mm × 3.912 mm with 1.75 mm max height, RoHS-compliant, lead finish Sn, MSL Level-1.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads up to 470 pF directly; rail-to-rail swing supports full-scale DAC output buffering |
| 2 | −IN A | Inverting input for Channel A - accepts voltages beyond supply rails; enables true single-supply transimpedance configurations |
| 3 | +IN A | Non-inverting input for Channel A - matched bias current path; used for high-impedance sensor front-ends (e.g., piezoelectric, thermopile) |
| 4 | V− | Negative supply terminal - connects to ground in single-supply operation; must be decoupled within 1 cm of pin |
| 5 | +IN B | Non-inverting input for Channel B - electrically isolated from Channel A; supports dual-path signal conditioning (e.g., I/Q demodulation) |
| 6 | −IN B | Inverting input for Channel B - identical CMVR and input impedance as Pin 2; allows independent gain-setting per channel |
| 7 | OUT B | Amplifier B output - independently driven; enables simultaneous processing of two analog signals without crosstalk degradation (>125 dB isolation) |
| 8 | V+ | Positive supply terminal - operates from 2.7 V to 24 V; internal regulation ensures stable GBW and slew rate across full range |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV722MMX/NOPB | Lower GBW (10 MHz), lower supply current (160 µA), rail-to-rail I/O but limited CMVR (to V− + 0.1 V) | Better suited for ultra-low-power sensor amps where speed <1 MHz suffices; cannot accept inputs below ground | Select LMV722MMX/NOPB only when quiescent current is primary constraint and input voltage stays within supply rails. |
| OPA2350UA/2K5 | Higher GBW (38 MHz), lower noise (7 nV/√Hz), same rail-to-rail I/O, but higher supply current (4.9 mA/amplifier) | Preferred for precision low-noise applications like medical ECG front-ends; less suitable for long-life battery operation | Choose OPA2350UA/2K5 when noise performance outweighs power budget, and 4.9 mA/amplifier is acceptable. |
Compared with LM6152BCMX, LMV722MMX/NOPB trades 85% bandwidth for 89% lower supply current and lacks true beyond-the-rails input, while OPA2350UA/2K5 offers superior noise and precision at 3.5× higher quiescent draw-making LM6152BCMX optimal for balanced high-speed, low-power, rail-flexible designs.

FAQ
What is the maximum capacitive load the LM6152BCMX can drive without oscillation?
The LM6152BCMX remains stable with capacitive loads up to 470 pF when configured with closed-loop gain ≥2. This capability eliminates the need for external isolation resistors in LCD column drivers, active filters, and coaxial cable interfaces. Stability is maintained due to its internal phase-reversal prevention circuit, which dynamically adjusts slew rate to counteract phase lag induced by load capacitance. For loads >470 pF, small series output resistance (<10 Ω) may be added to preserve stability without degrading DC accuracy.
Does the LM6152BCMX support true rail-to-rail input operation?
Yes, the LM6152BCMX provides greater-than-rail-to-rail input common-mode voltage range: −0.25 V to 5.25 V at 5 V supply, and −0.25 V to 24.25 V at 24 V supply. This allows input signals to extend 0.25 V beyond either supply rail, enabling direct interfacing with grounded sensors, bipolar transducers, or overdriven logic outputs without external level-shifting circuitry. The feature is enabled by TI's patented input stage topology and is verified across temperature and process corners.
What is the typical supply current of the LM6152BCMX at 3.3 V operation?
At 3.3 V supply, the LM6152BCMX draws 1.35 mA per amplifier (2.7 mA total for both channels), as specified in the 2.7 V DC Electrical Characteristics table. This value is confirmed across the full operating temperature range (0°C to +70°C) and represents a 5% reduction versus the 1.4 mA typical at 5 V. The low quiescent current enables multi-hour runtime in coin-cell or Li-ion–powered portable devices while retaining 75 MHz GBW and rail-to-rail functionality.
Can the LM6152BCMX be used in single-supply configurations with ground-referenced inputs?
Yes, the LM6152BCMX is explicitly designed for single-supply operation with ground-referenced inputs. Its input common-mode range extends to −0.25 V below V− (ground), allowing direct connection of 0 V–referenced sources such as thermocouples, bridge sensors, or microcontroller GPIOs. Combined with rail-to-rail output swing (0.01 V to 4.99 V at 5 V), it delivers full dynamic range without external biasing networks-reducing component count and PCB area in space-constrained designs.
What is the small-signal slew rate of the LM6152BCMX, and how does it differ from large-signal slew rate?
The LM6152BCMX has a small-signal slew rate of 5 V/µs (measured with ±4 V step at ±6 V supplies) and a large-signal slew rate of 45 V/µs. This 9× increase results from its patented input-stage speed-up circuit, which boosts slew rate proportionally to input differential voltage. Unlike conventional op amps with fixed slew limits, this behavior minimizes settling time for large-amplitude transients while maintaining low power during small-signal operation-critical for pulse amplification in barcode scanners and ultrasonic receivers.
