Product details
Overview
LM6152ACM-TI from Texas Instruments is a dual-channel 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, ADC buffering, and barcode scanner front-ends where speed, dynamic range, and power efficiency are critical.
For engineers reviewing the LM6152ACM-TI datasheet, LM6152ACM-TI pinout, LM6152ACM-TI application, or LM6152ACM-TI equivalent, key selection considerations include its rail-to-rail I/O capability across wide supply ranges, input overvoltage tolerance beyond rails, capacitive-load drive stability up to 470 pF, and verified performance at 2.7 V, 5 V, and 24 V supplies - all while maintaining sub-1.1 µs settling time to 0.01%.
Technical Context
The LM6152ACM-TI employs a patented input stage that enables greater-than-rail common-mode input voltage range (−0.25 V to +24.25 V) and dynamically increases slew rate with differential input amplitude - reaching >30 V/µs for large signals. This architecture eliminates phase reversal and improves stability when driving capacitive loads without external compensation.
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., 4 MHz at AV = −1, VS = 5 V with 6.8 pF compensation. The device achieves 84 dB CMRR and 91 dB PSRR at 5 V, with input bias current under 500 nA and input offset voltage as low as 0.3 mV (typical at 24 V).
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 |
|---|---|---|---|
| OPA2350UA | Lower GBW (38 MHz), lower supply current (1.8 mA), no input overvoltage tolerance beyond rails | Better DC precision (50 µV VOS), but unsuitable for overvoltage-tolerant front-ends | Select when ultra-low offset dominates over speed and rail exceedance capability |
| AD8662ARZ | Higher supply current (2.4 mA), narrower supply range (5 V to 16 V), fixed 12 MHz GBW | Superior CMRR (105 dB) and lower noise (5.2 nV/√Hz), but lacks dynamic slew enhancement | Select for precision low-noise applications where bandwidth <15 MHz suffices and overvoltage immunity is not required |
Compared with OPA2350UA and AD8662ARZ, LM6152ACM-TI uniquely combines rail-exceeding input range, dynamic slew-rate scaling, and 75 MHz bandwidth at sub-1.5 mA - making it optimal for portable high-speed signal chains where supply headroom is limited and transient fidelity is critical.

FAQ
What is the maximum capacitive load the LM6152ACM-TI can drive without oscillation?
The LM6152ACM-TI is stable driving capacitive loads up to 470 pF at closed-loop gains ≥2, thanks to its internal phase-shift compensation circuitry. This eliminates the need for external isolation resistors in ADC buffer or sensor interface applications. Performance validation is documented in Figure 27 and Section 7 of the SNOS752E datasheet, confirming stability with 470 pF at AV = +2 and VS = 5 V. For gains <2, consult layout guidelines and consider small series resistance at the output.
Does the LM6152ACM-TI support true rail-to-rail input operation beyond the supply rails?
Yes, the LM6152ACM-TI supports a greater-than-rail input common-mode voltage range of −0.25 V to (V+ + 0.25 V), verified across 2.7 V to 24 V supplies. This allows direct connection of signals exceeding V− or V+ - such as sensor outputs or DACs referenced to different supplies - without external clamping diodes or level shifters. This feature is explicitly specified in the "Input Common-Mode Voltage Range" parameter tables for all supply conditions in the SNOS752E datasheet.
What is the typical slew rate behavior of the LM6152ACM-TI under large-signal conditions?
The LM6152ACM-TI features a patented input-stage speed-up circuit that makes slew rate amplitude-dependent: it increases from 5 V/µs (small-signal) to 45 V/µs (large-signal) as differential input voltage rises. This dynamic response reduces phase lag and improves settling fidelity for fast transients - confirmed by Figure 27 ("Slew Rate vs. VDIFF") and the 1.1 µs settling time spec for a 2 V step. Unlike conventional op amps, this behavior enhances stability into capacitive loads.
Can the LM6152ACM-TI operate reliably from a 2.7 V single supply?
Yes, the LM6152ACM-TI is fully characterized and guaranteed for operation from 2.7 V to 24 V, including DC and AC specifications at 2.7 V. At 2.7 V, it delivers 80 MHz GBW (typical), 1.35 mA supply current per amplifier, and rail-to-rail output swing from 0.07 V to 2.64 V (RL = 10 kΩ). These values are explicitly listed in Sections 6.7 and 6.8 of the SNOS752E datasheet, confirming suitability for ultra-low-voltage portable designs.
What package options are available for the LM6152ACM-TI, and what is its moisture sensitivity level?
The LM6152ACM-TI is offered exclusively in an 8-pin SOIC (Package Drawing D, body size 4.902 mm × 3.912 mm) with RoHS-compliant lead finish (Sn) and moisture sensitivity level (MSL) 1 - rated for unlimited floor life at ≤30°C/60% RH and peak reflow temperature of 260°C. This is confirmed in the TI Package Option Addendum (6-Feb-2020), where LM6152ACM/NOPB and LM6152ACMX/NOPB are both marked "Level-1-260C-UNLIM".
