Product details
Overview
LM8262MM/NOPB from Texas Instruments is a dual rail-to-rail input/output operational amplifier in VSSOP-8 package, delivering 24MHz gain-bandwidth, 35V/µs slew rate, and ±125mA output short-circuit current per channel. It operates from 2.7V to 32V supply, supports unlimited capacitive load drive, and is optimized for TFT-LCD VCOM buffering and high-side/low-side sensing.
For engineers reviewing the LM8262MM/NOPB datasheet, LM8262MM/NOPB pinout, LM8262MM/NOPB application, or LM8262MM/NOPB equivalent, key selection criteria include rail-to-rail I/O swing at 3V, THD+N < 0.00022%, 12nV/√Hz input voltage noise, and verified stability with large capacitive loads without external compensation.
Technical Context
The LM8262MM/NOPB employs a high-speed, high-output-current output stage capable of sourcing/sinking ±125mA per channel while maintaining low distortion (0.00022% THD+N) and 50° phase margin at unity gain. Its input stage provides >90dB CMRR and rail-to-rail common-mode range extending beyond supply rails, enabling accurate high-side and low-side current sensing across full supply range.
Designed for capacitive-load-intensive applications, it eliminates need for isolation resistors or external compensation - unlike conventional op amps - due to internal compensation optimized for unlimited CL drive. Supply current remains stable (1.35mA typical) across 2.7V–32V operation, with minimal PSRR variation (±3.5 µV/V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 24MHz - enables stable closed-loop operation up to ~20MHz at G = +1 with 50° phase margin. |
| Slew Rate | 35V/µs - supports fast settling (430ns to 0.1%) for 10V step with 50pF load, critical for A/D buffer fidelity. |
| Supply Voltage Range | 2.7V to 32V - accommodates single-supply 3V systems and dual-supply ±15V industrial rails without redesign. |
| Output Short-Circuit Current | ±125mA per channel - sustains robust drive into low-Z loads (e.g., headphone amplifiers, VCOM lines) without latch-up. |
| Input Voltage Noise | 12nV/√Hz at 1kHz - preserves SNR in precision signal conditioning paths such as sensor front-ends. |
| THD+N | <0.00022% at 1kHz - ensures ultra-low distortion for audio and instrumentation-grade analog signal paths. |
| Rail-to-Rail I/O | Operates down to 3V supply with full input common-mode range (V− to V+) and output swing within 60mV of rails - maximizes dynamic range in low-voltage systems. |
Pinout & Package
VSSOP-8 (DGK) package: 3.00mm × 4.90mm body, 0.65mm pitch, exposed pad not present. RoHS-compliant, Sn finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives capacitive VCOM line or ADC input with unlimited CL stability. |
| 2 | −IN A | Inverting input A - forms summing node for precision feedback; sensitive to parasitic capacitance (layout-critical). |
| 3 | +IN A | Non-inverting input A - accepts rail-to-rail common-mode signals up to V+ + 0.5V, enabling high-side sensing. |
| 4 | V− | Negative supply - referenced for dual-supply operation or ground in single-supply mode; decoupling required. |
| 5 | +IN B | Non-inverting input B - independent channel input; identical rail-to-rail CMVR and CMRR as Channel A. |
| 6 | −IN B | Inverting input B - supports differential configurations or separate feedback loops per channel. |
| 7 | OUT B | Amplifier B output - fully independent output stage with same ±125mA short-circuit rating and THD+N performance. |
| 8 | V+ | Positive supply - supplies both channels; requires local 0.01µF ceramic + 4.7µF bulk decoupling per TI layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Unlimited capacitive load drive | Stable operation with any CL value - eliminates need for series isolation resistor in TFT-LCD VCOM drivers. |
| Rail-to-rail input common-mode range | Extends 0.5V beyond V− and V+, enabling direct connection to shunt resistors in high-side/low-side current sensing. |
| High output current per channel | ±125mA short-circuit rating - supports driving 600Ω headphones or charging large panel capacitances without gain compression. |
| Low distortion audio performance | 0.00022% THD+N at 1kHz - meets Class AB headphone amplifier requirements without external filtering. |
| Supply-insensitive parameters | PSRR ±3.5 µV/V and stable GBW/slew rate across 2.7V–32V - simplifies design across diverse power architectures. |

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 GBWP (6.4MHz), lower output current (±35mA), no unlimited CL drive - requires isolation resistor for >1nF loads. | Not suitable for TFT-LCD VCOM or high-current headphone drive; limited to low-speed sensor buffering. | Select when cost sensitivity outweighs speed/current needs and capacitive loads are ≤1nF. |
| OPA2350UA | Higher GBWP (38MHz), lower noise (7nV/√Hz), but only ±50mA short-circuit current and limited CL stability (≤100pF). | Preferred for low-noise instrumentation; unsuitable for VCOM or headphone loads requiring >±100mA drive. | Choose for precision low-noise signal chains where capacitive load is small and output current ≤50mA suffices. |
Compared with TLV2462IDR and OPA2350UA, the LM8262MM/NOPB uniquely combines unlimited capacitive load stability, ±125mA output current, and 24MHz bandwidth - making it irreplaceable in TFT-LCD VCOM driver and high-current audio buffer roles where alternatives require redesign or performance trade-offs.

FAQ
What is the maximum capacitive load the LM8262MM/NOPB can drive without oscillation?
The LM8262MM/NOPB is explicitly characterized for unlimited capacitive load drive - meaning it remains stable with any value of capacitive load (including >1µF) without requiring external isolation resistors or compensation networks. This capability is verified across its full operating range (2.7V–32V) and is a core differentiator versus standard op amps that require careful CL limiting or added series resistance.
Does the LM8262MM/NOPB support single-supply operation at 3V?
Yes, the LM8262MM/NOPB supports true single-supply operation down to 2.7V, with rail-to-rail input common-mode range extending from V− to V+ and output swing within 60mV of both rails at 3V. This enables full dynamic range utilization in battery-powered systems such as portable medical sensors and handheld test equipment using the LM8262MM/NOPB.
What is the thermal resistance (θJA) of the LM8262MM/NOPB in VSSOP-8 package?
The junction-to-ambient thermal resistance (θJA) for the LM8262MM/NOPB in DGK (VSSOP-8) package is 169.6°C/W under standard JEDEC PCB conditions (2-layer board, 1-in² copper). This value is critical for calculating maximum allowable power dissipation: PD(max) = (TJ(max) − TA) / θJA, where TJ(max) = 150°C and ambient temperature must be derated accordingly for continuous ±125mA output loading.
Can the LM8262MM/NOPB be used in high-side current sensing applications?
Yes - the LM8262MM/NOPB's input common-mode voltage range extends 0.5V beyond both supply rails (V− − 0.5V to V+ + 0.5V), allowing direct connection to high-side shunt resistors even when sensed voltage exceeds V+. Combined with >90dB CMRR, it delivers accurate, drift-free current measurement without level-shifting circuitry - a key advantage confirmed in TI's application notes for motor control and battery monitoring using the LM8262MM/NOPB.
Is the LM8262MM/NOPB pin-compatible with earlier LM8262 variants?
Yes, the LM8262MM/NOPB maintains identical VSSOP-8 (DGK) pinout and electrical specifications as prior LM8262 revisions, including the obsolete LM8262MM/NOPB marking. TI's revision H datasheet confirms full functional and mechanical compatibility, with only die-level improvements (e.g., updated ESD ratings, tighter thermal resistance) - no PCB or schematic changes are needed when migrating to the current LM8262MM/NOPB production version.
