Frequently Asked Questions
What is the output channel count and bandwidth of the LM4755TSX/NOPB?
The LM4755TSX/NOPB is a 2-channel stereo audio amplifier with a nominal bandwidth of 65 kHz, making it suitable for full-range audio reproduction in consumer electronics. Its 115 dB gain and compact 9-pin package simplify stereo amplifier designs with minimal external components.
For a television audio board, how does the LM4755TSX/NOPB reduce component count?
The LM4755TSX/NOPB integrates dual amplifier channels in a single 9-pin SIP package, eliminating the need for two separate mono amplifier ICs and their associated passive components. This integration reduces BOM cost and board area while delivering 65 kHz bandwidth and 115 dB gain for clear TV audio output.
What harmonic distortion level should designers expect from the LM4755TSX/NOPB?
The LM4755TSX/NOPB specifies 10% total harmonic distortion, which is typical for budget consumer audio amplifier ICs designed for mid-range TVs and multimedia speakers. Designers targeting audiophile-grade output should consider lower-distortion alternatives, while this part suits cost-optimized consumer products operating within standard 65 kHz audio bandwidth.
Is the LM4755TSX/NOPB compliant with RoHS regulations for lead-free production?
Yes, the NOPB suffix confirms the LM4755TSX/NOPB is manufactured lead-free and meets RoHS environmental directives. This compliance makes it suitable for export to European and Asian markets where lead-free soldering at reflow temperatures above 260°C is mandated.
