Product details
Overview
LM6152BCM 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 (1.1 µs to 0.01%).
For engineers reviewing the LM6152BCM datasheet, LM6152BCM pinout, LM6152BCM application, or LM6152BCM equivalent, key selection considerations include its rail-to-rail I/O capability across wide supply range, slew-rate enhancement with input differential voltage, capacitive-load drive stability up to 470 pF, and verified performance at 2.7 V, 5 V, and 24 V supply conditions.
Technical Context
The LM6152BCM 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 supply) and dynamically increases slew rate with rising input differential voltage-reaching 45 V/µs for large signals. This architecture improves phase margin when driving capacitive loads and reduces settling lag without external compensation in many configurations.
Its unity-gain-stable design supports closed-loop gains ≥1 (inverting) or ≥2 (non-inverting), with bandwidth highly dependent on gain and supply voltage: e.g., −10 gain yields ~1.97 MHz at 24 V, while −1 gain achieves ~6.6 MHz. GBW remains stable across supply voltages (75–80 MHz typical), and PSRR (91 dB) and CMRR (84 dB) are specified over full common-mode and supply ranges.
Key Specifications

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 |
|---|---|---|---|
| TLV2462IDR | Lower GBW (6.4 MHz), lower supply current (600 µA), rail-to-rail output only (not input) | Better suited for ultra-low-power, medium-bandwidth sensor buffering where input beyond rails is not required | Select TLV2462IDR when power budget <1 mA/channel and CMVR beyond rails is unnecessary |
| OPA2350UA | Higher GBW (38 MHz), higher slew rate (22 V/µs), rail-to-rail I/O, but higher supply current (4.9 mA/channel) | Preferred for precision high-speed applications demanding lower noise (7 nV/√Hz) and tighter offset (150 µV max) | Select OPA2350UA when 38 MHz bandwidth suffices and lower noise/offset outweighs 3.5× higher current draw |
Compared with TLV2462IDR and OPA2350UA, LM6152BCM uniquely balances 75 MHz bandwidth, 45 V/µs slew, rail-to-rail I/O, and sub-1.5 mA/channel consumption-making it optimal for portable instrumentation where speed, supply range, and efficiency intersect.

FAQ
What is the guaranteed minimum gain-bandwidth product for LM6152BCM across its operating supply range?
The LM6152BCM guarantees a minimum gain-bandwidth product of 75 MHz at 100 kHz test frequency under 5 V supply conditions, with typical values reaching 80 MHz at both 2.7 V and 24 V supplies per the datasheet's AC electrical characteristics tables. This ensures consistent high-frequency performance across the full 2.7 V to 24 V operating range, critical for stable closed-loop designs in variable-supply systems.
Does LM6152BCM support true rail-to-rail input operation, and what is the exact common-mode voltage range at 5 V supply?
Yes, LM6152BCM supports greater-than-rail-to-rail input operation. At 5 V supply (V+ = 5 V, V− = 0 V), its input common-mode voltage range extends from −0.25 V to +5.25 V-0.25 V beyond both supply rails-as confirmed in the DC electrical characteristics table. This eliminates input clamping requirements and simplifies single-supply front-end design for signals referenced to ground or V+.
Can LM6152BCM drive a 470 pF capacitive load without oscillation, and under what gain conditions?
Yes, LM6152BCM can drive up to 470 pF capacitive loads without oscillation when configured with closed-loop gain ≥2 (non-inverting) or ≥1 (inverting), as validated in the Application and Implementation section. Its patented input-stage speed-up circuit compensates for phase lag induced by capacitive loading, maintaining stability where conventional op amps require isolation resistors or complex compensation networks.
What is the maximum output voltage swing for LM6152BCM when loaded with 100 kΩ at 5 V supply?
At 5 V supply and 100 kΩ load, LM6152BCM delivers a guaranteed minimum output swing of 0.02 V to 4.97 V (i.e., within 20 mV of each rail), with typical performance reaching 0.01 V to 4.99 V. This rail-to-rail capability is explicitly specified in the 5.0 V DC Electrical Characteristics table and enables full utilization of ADC reference ranges in low-voltage data acquisition systems.
Is LM6152BCM qualified for industrial temperature range, and what is its specified operating ambient temperature?
Yes, LM6152BCM is rated for the industrial operating temperature range of 0 °C to +70 °C, as stated in the Recommended Operating Conditions table. This specification applies to all LM6152 variants including LM6152BCM, making it suitable for commercial and industrial equipment deployed in controlled-environment applications without extended temperature requirements.
