Low supply current about 4.18 mA typical

Low input offset ~1.3 mV typical

Input bias current ~1.4 µA typical

Wide supply span 3 V to 12 V, supports single-supply or split supplies

Small SOT-23-6 footprint, surface-mount

ROHS3 compliant, lead-free

Key Advantages

High speed with excellent drive current enables video, ADC driver, and fast signal conditioning tasks

Rail-to-rail output maximizes dynamic range on low-voltage rails

Low power for its speed class reduces heat and consumption

Small package saves PCB space and supports dense layouts

Wide supply range adds design flexibility across 3–12 V systems

Low offset and bias support precision in DC and low-frequency performance

Proven TI platform with strong ecosystem and application notes

Packaging

Type Tape & Reel (TR) for automated pick-and-place

Package SOT-23-6, supplier device package SOT-23-6

Material Molded epoxy encapsulation with matte-tin plated leads (lead-free, ROHS3 compliant)

Size SOT-23-6 is ultra-compact; typical body ~3.0 mm x 1.8 mm with low profile height (refer to datasheet for exact dimensions)

Pin configuration Typical single op-amp pinout in SOT-23-6 includes IN+, IN−, OUT, V+, V−, and one extra pin that may be shutdown or NC depending on variant; confirm exact pin functions in the datasheet

Mounting Surface Mount (SMT)

Thermal characteristics SOT-23 packages have modest thermal dissipation; thermal resistance depends on PCB copper and airflow; check datasheet for θJA/θJC guidance
