## Summary description

Dual operational amplifier Texas Instruments LME49720NA/NOPB in PDIP‑8 package designed for high‑fidelity audio applications. Contains two matched amplifiers optimized for low distortion and low noise in audio signal paths. Suitable for preamplifiers, headphone amplifiers, DAC output stages and other analog audio circuits requiring precise, low‑noise amplification.

## Long description

The Texas Instruments LME49720NA/NOPB is a dual operational amplifier in a PDIP‑8 package engineered for high‑fidelity audio applications. It contains two matched amplifiers optimized for low distortion and low noise, making it suitable for signal paths where sonic transparency and precise amplification are required. Typical uses include preamplifiers, headphone amplifiers, DAC output stages and other analog audio circuits that demand accurate, low‑noise performance.
Advantages
The pair of matched amplifiers provides consistent channel balance and reduced offset between channels. Low total harmonic distortion and a wide open‑loop gain contribute to accurate reproduction of audio signals with minimal coloration. The PDIP‑8 through‑hole package supports easy prototyping and replacement in consumer and professional audio equipment. Thermal and electrical characteristics are designed to maintain stability across typical audio operating conditions.
Suitable for
 Preamplifier stages in stereo audio systems
 Headphone amplifiers and portable audio docks
 DAC output filters and line drivers
 High‑quality analog signal conditioning and mixing consoles
Key specifications
 Dual op‑amp configuration with two matched channels
 PDIP‑8 through‑hole package for easy mounting and prototyping
 Designed for low noise and low total harmonic distortion in audio band
 Wide open‑loop gain suitable for high‑fidelity amplification
 Supply range and quiescent current optimized for typical audio applications
How to use
Install the PDIP‑8 package into a compatible through‑hole PCB footprint or a socket, observing correct pin orientation and supply polarity. Use recommended power supply decoupling close to the device pins to minimize supply noise. Configure the amplifier in the desired topology (inverting, non‑inverting, differential) using appropriate feedback and input components; ensure component values match the required bandwidth and gain. Match layout and grounding practices for low noise: keep input traces short, separate analog and digital grounds where relevant, and place bypass capacitors as close as possible to the supply pins.
Usage recommendations
For best audio performance, use low‑noise resistors and quality film capacitors in the signal path, maintain symmetrical layout for stereo channels, and follow the manufacturer's recommendations for supply decoupling. Avoid driving the outputs into heavy loads without proper output stage buffering, and allow adequate ventilation if operating at elevated supply voltages.
