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
