Product details

Description

of Operation TA2131FNG has a bass boost function for bass sound reproduction built-in to the power amplifier.With the bass boost function, at medium levels and lower, channel A and channel B are added for the low frequency component, and output to BST amplifier 2 (BST2) in negative phase.That signal is inverted and added before being subjected to bass boost.If the signal of the low-frequency component reaches a high level, the boost gain is controlled to main a low distortion (see Fig.1).ww

Features

a built-in bass boost function with AGC, and is capable of bass amplification of DAC output and analog signals such as tuner. Features.
Low current consumption: ICCQ (VCC1) = 0.55 mA (typ. ) ICCQ (VCC2) = 0.20 mA (typ. ) Output power: Po = 8 mW (typ. ) (VCC1 = 2.8 V, VCC2 = 1.2 V, f = 1 kHz, THD = 10%, RL = 16 Ω) Low noise: Vno =.
102dBV (typ. ) Built-in low-pass boost (with AGC) I/O pin for beep sound.
