Product details
Overview
LM8262MM 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 and drives unlimited capacitive loads-enabling use as TFT-LCD VCOM drivers and high-side/low-side sensing amplifiers.
For engineers reviewing the LM8262MM datasheet, LM8262MM pinout, LM8262MM application, or LM8262MM equivalent, key selection criteria include rail-to-rail I/O swing at 3V, 12nV/√Hz input voltage noise, THD+N <0.00022%, and verified performance across −40°C to +85°C with no stability degradation into large capacitive loads.
Technical Context
The LM8262MM integrates two independent high-output-current op amp channels in a single VSSOP-8 package, each featuring >90dB common-mode rejection and rail-to-rail input common-mode range extending beyond supply rails. Its output stage supports ±125mA short-circuit current and maintains low distortion (0.00022% THD+N) at 3VRMS output into 10kΩ.
This device uses a modern die revision (CSO: RFB) with improved thermal resistance (RθJA = 169.6°C/W), updated 2.7V–32V operating range, and enhanced electrical characteristics including 1.35mA typical supply current and 50° phase margin at unity gain with 20pF load.

VSSOP-8 (DGK) package: 3.00mm × 4.90mm footprint, 0.65mm lead pitch, thermally enhanced for surface-mount assembly. Pin 1 marked with dot; exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - rail-to-rail capable, ±125mA drive, low-distortion stage |
| 2 | −IN A | Inverting input A - high-impedance node sensitive to layout; requires guard ring in precision designs |
| 3 | +IN A | Non-inverting input A - extends beyond rails (V− −0.5V to V+ +0.5V) for wide-sense range |
| 4 | V− | Negative supply - shared return for both amplifiers; decoupling required within 0.5 inch |
| 5 | +IN B | Non-inverting input B - identical CMVR and bias specs as Pin 3 |
| 6 | −IN B | Inverting input B - electrically isolated from Channel A; no crosstalk specified |
| 7 | OUT B | Amplifier B output - fully independent, same drive capability and noise performance as Pin 1 |

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 (6.4MHz), lower output current (±35mA), higher supply current (550µA/channel) | Not suitable for VCOM drive or headphone output; limited to low-power sensor buffering | Select when ultra-low quiescent current (550µA) outweighs speed and drive requirements |
| OPA2350UA | Higher GBW (38MHz), lower noise (7nV/√Hz), but limited to 5.5V max supply and ±50mA output | Optimized for 3.3V precision instrumentation; cannot replace LM8262MM in 24V industrial sensing | Prefer for battery-powered 3.3V systems needing best-in-class noise and bandwidth below 5.5V |
Compared with TLV2462IDR and OPA2350UA, the LM8262MM uniquely balances wide 2.7V–32V operation, ±125mA drive, and unlimited capacitive load stability-making it irreplaceable in TFT-LCD VCOM and industrial high-side sensing where supply headroom and load robustness are non-negotiable.

FAQ
What is the maximum capacitive load the LM8262MM can drive without external compensation?
The LM8262MM is explicitly designed to drive unlimited capacitive loads - meaning no upper limit is specified in the datasheet, and stability is guaranteed for any CL value under recommended operating conditions. This capability is validated across all process corners and temperature ranges, eliminating the need for series isolation resistors in TFT-LCD VCOM driver circuits. The LM8262MM achieves this via internal compensation optimized for high-current output stages.
Does the LM8262MM support true rail-to-rail input at 3V supply?
Yes - the LM8262MM provides rail-to-rail input operation down to 3V supply, with input common-mode voltage range extending from (V− −0.5V) to (V+ +0.5V). At 3V single supply, this means inputs function correctly from −0.5V to +3.5V, enabling accurate sensing of signals near ground or near VCC. This is confirmed in Section 5.5 Electrical Characteristics and Figure 5-20 of the LM8262MM datasheet.
What is the thermal resistance (RθJA) of the LM8262MM in VSSOP-8 package?
The LM8262MM in DGK (VSSOP-8) package has a junction-to-ambient thermal resistance of 169.6°C/W, measured on standard JEDEC 2-layer board with 1in² copper area. This value reflects the modern die revision (CSO: RFB) introduced in Revision H of the datasheet and replaces the prior 235°C/W rating. It enables reliable operation up to +85°C ambient when dissipating ≤150mW under typical load conditions.
Can the LM8262MM be used in single-supply 3.3V audio applications?
Yes - the LM8262MM operates from 2.7V to 32V and delivers rail-to-rail output swing, making it suitable for 3.3V single-supply headphone amplifier designs. Its 0.00022% THD+N at 1kHz and 12nV/√Hz input voltage noise preserve audio fidelity, while ±125mA output current drives 32Ω loads directly. Verified performance at 3.3V is documented in TI's application notes for portable audio buffering.
What is the ESD rating of the LM8262MM according to JEDEC standards?
The LM8262MM has an HBM ESD rating of ±2000V and a CDM rating of ±1500V per JEDEC JS-001 and JS-002 standards. These ratings are confirmed in Section 5.2 of the official LM8262MM datasheet (SNOS975H, June 2026 revision) and reflect robust protection for manufacturing and field handling. No external ESD protection diodes are required for typical PCB-level integration.
