Product details
Overview
LM8262MMX from Texas Instruments is a dual rail-to-rail input/output operational amplifier optimized for high-output-current, unlimited capacitive load driving, and wide supply operation (2.7V to 32V). It delivers 35 V/µs slew rate, 24 MHz gain-bandwidth product, ±125 mA short-circuit output current per channel, and 12 nV/√Hz input voltage noise - enabling use in TFT-LCD VCOM drivers and precision A/D converter buffering.
For engineers reviewing the LM8262MMX datasheet, LM8262MMX pinout, LM8262MMX application, or LM8262MMX equivalent, key selection criteria include its rail-to-rail I/O swing at 3V, 90 dB CMRR for high-side/low-side sensing, THD+N < 0.00022%, and verified stability with unlimited capacitive loads - all in an 8-pin VSSOP package.
Technical Context
The LM8262MMX employs a robust output stage capable of sourcing/sinking ±125 mA while maintaining low distortion (0.00022% THD+N) and stable unity-gain operation into any capacitive load. Its input stage provides > rail-to-rail common-mode range and 90 dB CMRR, enabling accurate differential sensing across full supply rails without clipping or accuracy loss.
Designed for flat-panel display VCOM driver applications, it integrates high-speed performance (24 MHz GBW, 35 V/µs SR) with low-noise operation (12 nV/√Hz, 1 pA/√Hz) and supply-insensitive parameters - allowing reliable operation from 2.7V single supply to ±16V dual supply without recalibration or compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 32V - supports single-supply 3V logic interfacing and high-voltage industrial signal conditioning without level-shifting. |
| Gain-Bandwidth Product | 24 MHz - enables stable closed-loop operation up to ~200 kHz at G = +100, suitable for anti-aliasing and reconstruction filters. |
| Slew Rate | 35 V/µs - ensures faithful reproduction of fast transient signals (e.g., LCD column drive edges) without slew-induced distortion. |
| Output Short-Circuit Current | ±125 mA per channel - sustains high-current transients into heavy loads (e.g., VCOM bus capacitance > 1 µF) without latch-up or thermal shutdown. |
| Input Voltage Noise | 12 nV/√Hz at 1 kHz - preserves SNR in low-level sensor amplification and precision buffer stages where noise dominates dynamic range. |
| THD+N | < 0.00022% at 1 kHz - meets high-fidelity audio (headphone amp) and measurement-grade analog front-end requirements. |
| Common-Mode Rejection | 90 dB - maintains accuracy in high-side current sensing and differential instrumentation where supply ripple couples into inputs. |
Pinout & Package
LM8262MMX is housed in an 8-pin VSSOP (DGK) package measuring 3.00 mm × 4.90 mm, optimized for space-constrained PCB layouts while maintaining thermal performance (RθJA = 169.6 °C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives capacitive VCOM bus or ADC input with rail-to-rail swing and ±125 mA capability. |
| 2 | −IN A | Inverting input A - forms feedback node for precision gain-setting networks; sensitive to parasitic capacitance. |
| 3 | +IN A | Non-inverting input A - accepts rail-to-rail common-mode signals (V− to V+) for high-side/low-side sensing. |
| 4 | V− | Negative supply - referenced ground in single-supply mode; must be decoupled with 0.01 µF ceramic + 4.7 µF bulk capacitor. |
| 5 | +IN B | Non-inverting input B - independent second channel input; shares same CMVR and noise specs as Channel A. |
| 6 | −IN B | Inverting input B - supports dual-channel configurations such as differential-to-single-ended conversion or stereo buffering. |
| 7 | OUT B | Amplifier B output - identical performance to OUT A; enables dual VCOM control or dual-channel headphone drive. |
| 8 | V+ | Positive supply - accepts up to 32V; supplies both channels; requires low-inductance decoupling ≤0.5″ from pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Operates with input common-mode range from V− to V+ and output swing within 60 mV of rails at 2 kΩ load - eliminates need for level-shifting in 3V systems. |
| Unlimited capacitive load drive | Stable with any value of capacitive load (including >1 µF TFT panel buses) without external isolation resistors or compensation. |
| High output current | ±125 mA per channel at 32V supply - drives heavy capacitive or resistive loads without gain compression or thermal foldback. |
| Low distortion | 0.00022% THD+N at 1 kHz - preserves signal fidelity in audio paths and precision measurement chains where harmonic artifacts degrade accuracy. |
| Supply-insensitive performance | GBW, slew rate, and offset drift remain stable across 2.7V–32V supply range - simplifies design across multiple power domains without recalibration. |

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), lower output current (±30 mA), higher input bias current (±10 nA vs. ±0.4 µA), no unlimited cap load guarantee. | Better suited for low-power, low-frequency sensor interfaces; not recommended for VCOM or high-current audio. | Select TLV2462IDR only when supply current <1 mA is critical and capacitive load <100 pF. |
| OPA2350UA | Higher GBW (38 MHz), lower noise (7 nV/√Hz), but limited capacitive load drive (≤ 100 pF), narrower supply range (2.7V–5.5V). | Ideal for high-speed, low-noise signal chain buffering where load is resistive or lightly capacitive. | Choose OPA2350UA for bandwidth-critical ADC front-ends with clean PCB layout; avoid for TFT-LCD or heavy capacitive loads. |
Compared with TLV2462IDR and OPA2350UA, LM8262MMX uniquely combines unlimited capacitive load stability, ±125 mA output current, and 24 MHz GBW across 2.7V–32V - making it irreplaceable in VCOM driver and high-current precision buffer roles where alternatives require external compensation or fail under load.

FAQ
What is the maximum capacitive load the LM8262MMX can drive without oscillation?
The LM8262MMX is explicitly designed and tested for unlimited capacitive load drive - meaning it remains stable with any value of capacitive load, including multi-microfarad TFT-LCD VCOM buses. This eliminates the need for series isolation resistors or external compensation networks that degrade settling time and signal fidelity in the LM8262MMX application.
Does the LM8262MMX support single-supply operation at 3.3V?
Yes, the LM8262MMX operates from 2.7V to 32V total supply range, fully supporting 3.3V single-supply operation. Its rail-to-rail input and output stages deliver full-scale swing from V− (ground) to V+ (3.3V), and its 90 dB CMRR ensures accurate sensing even with supply ripple - making it ideal for 3.3V embedded systems using the LM8262MMX.
What is the thermal resistance (RθJA) of the LM8262MMX in its VSSOP package?
The LM8262MMX in the 8-pin VSSOP (DGK) package has a junction-to-ambient thermal resistance of 169.6 °C/W under standard JEDEC PCB mounting conditions. This value assumes proper copper pour and decoupling; actual thermal performance improves with enhanced PCB copper area and airflow - critical when operating the LM8262MMX near its ±125 mA output limit.
Can the LM8262MMX replace older LM8262 variants like LM8262MM/NOPB?
Yes, the LM8262MMX/NOPB.B is the active, drop-in replacement for obsolete LM8262MM/NOPB, sharing identical pinout, electrical specifications, and VSSOP packaging. TI migrated production to a new die (CSO = RFB) with improved thermal resistance and updated ESD ratings - all while maintaining full functional and mechanical compatibility with legacy LM8262MMX designs.
What is the input voltage noise density of the LM8262MMX at 1 kHz?
The LM8262MMX exhibits an input voltage noise density of 12 nV/√Hz at 1 kHz, confirmed in the official TI datasheet (SNOS975H, Section 5.5). This low-noise performance, combined with 1 pA/√Hz input current noise, makes the LM8262MMX suitable for precision sensor amplification and high-resolution data acquisition where noise directly limits system dynamic range.
