Product details
Overview
LM6152ACM from Texas Instruments is a dual rail-to-rail input/output operational amplifier optimized for low-voltage, high-speed portable instrumentation. It delivers 75 MHz gain-bandwidth at 5 V, 1.4 mA/amplifier supply current, ±0.25 V to 5.25 V input common-mode range, and 0.01 V to 4.99 V output swing - enabling high-fidelity signal conditioning in battery-powered barcode scanners and ADC front-ends.
For engineers reviewing the LM6152ACM datasheet, LM6152ACM pinout, LM6152ACM application, or LM6152ACM equivalent, key selection criteria include its rail-to-rail I/O capability at 2.7–24 V supply, slew-rate scalability with input differential voltage (up to 45 V/µs large-signal), fast 1.1 µs settling time to 0.01%, and SOIC-8 package compatibility with space-constrained PCB layouts.
Technical Context
The LM6152ACM employs a patented input stage that prevents phase reversal and dynamically increases slew rate with rising input differential voltage - enabling stable operation into capacitive loads up to 470 pF without external compensation. Its unity-gain-stable architecture supports closed-loop gains ≥2 in non-inverting configurations and ≥1 in inverting topologies.
Unlike conventional bipolar op amps, the LM6152ACM maintains >84 dB CMRR and 91 dB PSRR across 2.7–24 V supplies while delivering rail-to-rail output swing even at 2.7 V - critical for maximizing dynamic range in low-voltage data acquisition systems where headroom is constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 75 MHz @ 100 kHz - enables stable unity-gain buffer or gain-of-10 amplification up to ~7.5 MHz |
| Slew Rate (Large Signal) | 45 V/µs - supports fast transient response in pulse-amplification and active filter applications |
| Supply Current per Amplifier | 1.4 mA - allows dual-channel high-speed amplification on single-cell Li-ion (3.0–3.7 V) or two-cell alkaline (2.7–3.0 V) supplies |
| Input Common-Mode Range | −0.25 V to 5.25 V @ 5 V supply - accepts signals beyond rails, eliminating level-shifting in sensor interface circuits |
| Rail-to-Rail Output Swing | 0.01 V to 4.99 V @ 5 V / 100 kΩ load - preserves full 4.98 V peak-to-peak dynamic range for 12-bit+ ADC drivers |
| Settling Time (2 V step) | 1.1 µs to 0.01% - meets timing budgets in multiplexed data acquisition systems sampling at ≥500 kSPS |
| CMRR / PSRR | 84 dB / 91 dB - rejects power-supply noise and common-mode interference in noisy industrial environments |

| 4 | V− | Negative supply terminal - tied to ground in single-supply operation or negative rail in split-supply systems |
| 5 | +IN B | Non-inverting input for Channel B - used for differential pair, dual-channel filtering, or independent signal paths |
| 6 | −IN B | Inverting input for Channel B - enables matched gain-setting with Channel A in dual-op-amp topologies |
| 7 | OUT B | Amplifier B output - provides second analog channel without adding discrete IC footprint |
| 8 | V+ | Positive supply terminal - accepts 2.7–24 V DC; decoupling capacitor required within 1 cm |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Extends 0.25 V beyond both supply rails - eliminates need for input biasing resistors in single-supply sensor interfaces |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV722MM/NOPB | Lower 10 MHz GBW, 1.25 mA/amplifier, 2.7–5.5 V only - lacks high-voltage operation and slew-rate scalability | Better suited for ultra-low-power sensor nodes (<100 kSPS), not high-speed data acquisition | Select when supply is strictly ≤5.5 V and bandwidth ≤1 MHz suffices; avoid for >5 V or >10 MHz needs |
| OPA2350UA/2K5 | Higher 38 MHz GBW, 4.9 mA/amplifier, rail-to-rail I/O, but no slew-rate boost - fixed 22 V/µs large-signal slew | Preferred for precision low-noise applications (7 nV/√Hz), not capacitive-load stability-critical designs | Choose for low-noise audio or medical sensing; LM6152ACM remains superior for 470 pF load drive and battery-life-sensitive systems |
Compared with LMV722MM/NOPB and OPA2350UA/2K5, the LM6152ACM uniquely balances 75 MHz bandwidth, 45 V/µs slew-rate scalability, and 1.4 mA/amplifier efficiency across 2.7–24 V - making it the only option supporting both low-voltage portability and high-voltage industrial signal chains without performance trade-offs.

FAQ
What is the operating temperature range for the LM6152ACM?
The LM6152ACM is specified for operation from 0°C to +70°C ambient temperature. This commercial-grade range aligns with its intended use in portable instrumentation, barcode scanners, and industrial control modules where environmental extremes are managed externally. The device's thermal resistance (RθJA = 193°C/W) and 150°C maximum junction temperature ensure reliable operation within this range under typical PCB layout conditions with adequate copper pour.
Does the LM6152ACM support single-supply operation?
Yes, the LM6152ACM fully supports single-supply operation from 2.7 V to 24 V. Its rail-to-rail input common-mode range extends 0.25 V below V− and 0.25 V above V+, allowing direct interfacing with ground-referenced sensors or microcontroller ADC references. The rail-to-rail output swing (e.g., 0.01 V to 4.99 V at 5 V supply) maximizes usable dynamic range without level-shifting circuitry - a key advantage in battery-powered systems using LM6152ACM.
Can the LM6152ACM drive a 470 pF capacitive load stably?
Yes, the LM6152ACM is explicitly characterized to drive ≥470 pF capacitive loads stably at closed-loop gains ≥2 without external compensation. This capability stems from its patented input-stage speed-up circuit, which increases slew rate under large differential inputs and improves phase margin. For LM6152ACM in non-inverting gain-of-2 configuration, 470 pF loading causes bandwidth reduction but no oscillation - verified in TI's SNOS752E datasheet Figure 17 and Application Section 7.
What is the typical supply current for the LM6152ACM at 2.7 V?
At 2.7 V supply, the LM6152ACM draws 1.35 mA per amplifier (2.7 mA total for both channels), as confirmed in Section 6.7 of the SNOS752E datasheet. This ultra-low quiescent current enables dual-channel high-speed amplification in energy-constrained applications such as handheld meters or wireless sensor nodes powered by coin cells or single Li-ion batteries - a defining feature distinguishing LM6152ACM from higher-current alternatives.
Is the LM6152ACM pin-compatible with other devices in the LM615x family?
Yes, the LM6152ACM shares identical SOIC-8 (D08A) pinout with all LM6152 variants (e.g., LM6152BCM/NOPB) and is functionally compatible with LM6152BC and LM6152AC grades. Pin assignments - including V+, V−, OUT A/B, and ±IN A/B - match exactly per Section 5 of SNOS752E. However, AC-grade devices like LM6152ACM offer tighter input offset voltage (0.54 mV typ) versus BC-grade (0.3 mV typ), so substitution requires verification of offset-critical system requirements.
