Low Consumption Current Stereo Headphone Power Amplifier for Portable CD (3V Use)

The TA2120FNG is a low consumption current stereo

headphone power amplifier developed for portable CD players

(3V). This IC has active bass boost, output limiter, input pin for

beep sound.

Features

• Low consumption current: ICCQ = 1.9 mA (C-CUP) (typ.)

ICCQ = 2.6 mA (OCL) (typ.)

• Two kinds of gain mode available: GV = 16dB or 8.5dB

• Output power (VCC = 2.0 V, f = 1 kHz, THD = 10%, RL = 16 Ω)

Weight: 0.14 g (typ.)

Po = 8 mW (typ.)

• Low noise: Vno = −98dBV (typ.)

• Built-in the center amplifier ON/OFF function.

(Favorable for low dissipation current in the C-Couple output configuration)

• Built-in active bass boost system

• Built-in output limiter function

• Input pin for beep sound

• Excellent ripple rejection ratio

• Built-in capacitor for reducing buzz noise

• Built-in power mute

• Built-in a power on/off switch

• Operating supply voltage range (Ta = 25°C): VCC = 1.8~4.5 V
