Checking for live stock

Texas Instruments LM380N‑8/NOPB is a rugged, precision 2.5 W Class‑AB audio power amplifier in an 8‑pin PDIP through‑hole package. Engineered for industrial, educational, and audio applications, it delivers robust performance with built-in protections. Moreover, compared to generic 78L05 or other low-power amplifiers, this part delivers higher audio fidelity, robust short-circuit resilience, and consistent supply-chain support for scale-up scenarios.

Special Features of the Product

Supply Voltage: 10 V to 22 V; typical use at 12 V, 15 V, or 18 V.
Operating Current / Quiescent Drain: ~7 mA; low quiescent power ~0.13 W at 18 V.
Package / Material: Standard 8‑pin PDIP (through‑hole), dimensions ~9.27 × 6.35 × 3.3 mm.
Operating Temp Range: 0 °C to +70 °C (TA).
Protection Features: Internal short‑circuit and thermal limiting.
Additional: Fixed gain ≈34 dB, high peak current ~1.3 A, high input impedance ~150 kΩ.

Unparalleled Benefits and Use Cases

The LM380N-8/NOPB is an excellent choice for speaker drivers, intercom systems, alarm modules, and embedded audio projects in industrial, educational, or consumer applications. Its wide voltage range (10–22 V) and internal protections (thermal, short-circuit) make it reliable and maintenance-free. The compact 8-pin DIP design simplifies prototyping and board layout, while the low idle drain (≈approximately 0.13 W) ensures energy-efficient operation.
