1 / 5 page Ordering number : ENN7139 O3001TN (OT) No. 7139-1/5 Overview The LA2901V is a high output level 4-channel line amplifier designed for car audio systems. This line amplifier provides an output signal with a significantly higher amplitude than the output signal provided by earlier preamplifiers. This higher amplitude significantly improves the signal-to-noise ratio in the connection from the main unit to the external power amplifier, and results in improved power amplifier performance. The LA2901V also significantly reduces the required mounting area by cutting in half the number of external capacitors required for boosting the signal-system supply voltage and is available in SSOP miniature package. Functions and Features • High output level (5.3 Vrms) • Low output noise voltage (12 µV) • Low total harmonic distortion (0.004%) • High ripple rejection ratio (70 dB) • Fewer external parts required • Excellent audio fidelity Package Dimensions unit: mm 3175B-SSOP24 (275 mil) 1 7.8 24 0.65 0.22 (0.33) 0.15 SANYO: SSOP24 (275 mil) [LA2901V] LA2901V SANYO Electric Co.,Ltd.
