Low Current Consumption Headphone Amplifier for Portable MD Player (With Bass Boost
Function)
The TA2131FN is a low current consumption headphone
amplifier developed for portable digital audio. It is particularly
well suited to portable MD players that are driven by a single dry
cell. It also 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
· Outstanding ripple rejection ratio
· Built-in power mute
· Built-in power ON/OFF switch
· Operating supply voltage range (Ta = 25°C): VCC1 = 1.8~4.5 V
VCC2 = 0.9~4.5 V
Weight: 0.14 g (typ.)
