Product details
Overview
LM6152BCMX/NOPB from Texas Instruments is a dual rail-to-rail input/output operational amplifier optimized for high-speed, low-power portable instrumentation. 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), enabling precision signal conditioning in battery-powered barcode scanners and ADC front-ends.
For engineers reviewing the LM6152BCMX/NOPB datasheet, LM6152BCMX/NOPB pinout, LM6152BCMX/NOPB application, or LM6152BCMX/NOPB equivalent, key selection criteria include its 1.4 mA/amplifier supply current at 5 V, > rail-to-rail input CMVR (−0.25 V to 5.25 V), fast 1.1 µs settling time (2 V step, 0.01%), and SOIC-8 package compatibility with space-constrained PCB layouts.
Technical Context
The LM6152BCMX/NOPB employs a patented input stage that dynamically increases slew rate with input differential voltage-enabling stable operation into 470 pF capacitive loads without oscillation while maintaining 10% overshoot. Its rail-to-rail input extends beyond supply rails (−0.25 V to +24.25 V), eliminating common-mode range concerns in single-supply systems.
This dual op amp operates across 2.7 V to 24 V supplies, with guaranteed performance at 0°C to +70°C. At 2.7 V, it sustains 80 MHz GBW; at 24 V, PSRR reaches 95 dB and CMRR hits 94 dB-supporting wide dynamic range in both low-voltage portable and industrial line-powered applications.

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 |
|---|---|---|---|
| TLV2462IDR | Lower GBW (6.4 MHz), higher supply current (550 µA/ch), but superior offset voltage (0.4 mV typ) | Better DC precision for low-frequency sensor conditioning; unsuitable for >1 MHz signal paths | Select TLV2462IDR when microvolt-level DC accuracy outweighs bandwidth needs in battery-powered IoT nodes |
| OPA2350UA | Higher GBW (38 MHz), lower noise (7 nV/√Hz), but narrower input CMVR (to V+ − 1.5 V) | Preferred for audio and low-noise medical biosensors; cannot accept inputs beyond V+ rail | Choose OPA2350UA for low-noise, moderate-speed applications where rail-to-rail input beyond supplies is not required |
Compared with TLV2462IDR and OPA2350UA, LM6152BCMX/NOPB uniquely balances 75 MHz bandwidth, rail-to-rail input beyond supplies, and 1.4 mA power consumption-making it the only dual op amp capable of driving fast ADCs in portable instrumentation without sacrificing supply flexibility or dynamic range.

FAQ
What is the maximum capacitive load the LM6152BCMX/NOPB can drive without oscillation?
The LM6152BCMX/NOPB can drive up to 470 pF capacitive loads at gains of 2 or higher without oscillation, thanks to its patented slew-rate enhancement circuit that compensates for phase lag. This capability eliminates the need for external isolation resistors in ADC buffer and cable-driving applications, preserving signal integrity while reducing BOM count. For optimal stability, TI recommends verifying layout parasitics and using the recommended 10 kΩ feedback resistor with optional compensation capacitor.
Does the LM6152BCMX/NOPB support true rail-to-rail input operation beyond the supply rails?
Yes, the LM6152BCMX/NOPB supports input voltages from −0.25 V below V− to +0.25 V above V+, confirmed across 2.7 V to 24 V supply ranges. This "beyond-the-rails" input capability allows direct interfacing with sensors whose outputs exceed the op amp's supply-such as thermocouples or piezoelectric transducers-without external level-shifting circuitry. The feature is explicitly characterized in the datasheet's DC electrical characteristics tables for all supply voltages.
What is the typical supply current of the LM6152BCMX/NOPB at 2.7 V and 24 V operation?
At 2.7 V supply, the LM6152BCMX/NOPB draws 1.35 mA per amplifier; at 24 V, it draws 1.6 mA per amplifier-both well within its 1.4 mA typical rating at 5 V. This flat current profile across voltage ensures predictable battery drain in wide-input-range portable systems. The slight increase at high voltage reflects internal bias optimization and is fully specified in Section 6.7 and 6.9 of the SNOS752E datasheet.
Can the LM6152BCMX/NOPB be used in single-supply 3.3 V systems with 12-bit ADCs?
Yes, the LM6152BCMX/NOPB is fully functional at 3.3 V and ideal for buffering 12-bit ADCs. Its rail-to-rail output delivers 0.01 V to 3.29 V swing (typical), providing >99.7% of full-scale range-translating to <0.3 LSB loss in effective resolution. Input CMVR spans −0.25 V to 3.55 V, accommodating grounded-sensor configurations. Settling time remains ≤1.2 µs (0.01%) at 3.3 V, meeting timing requirements for 1 MSPS sampling rates.
How does the LM6152BCMX/NOPB's slew rate vary with input signal amplitude?
The LM6152BCMX/NOPB features amplitude-dependent slew rate: small-signal (±4 V step) is 5 V/µs, while large-signal (±4 V step at ±6 V supply) reaches 24 V/µs, and maximum observed is 45 V/µs. This behavior stems from its speed-up circuit that increases drive strength as input differential voltage rises-reducing phase lag into capacitive loads and improving transient response. Figure 27 in the SNOS752E datasheet plots this nonlinear relationship explicitly.
