Low Consumption Current Stereo Headphone Power Amplifier for Portable CD (3V Use)
The TA2120FN 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 )
Po = 8 mW (typ.)
· Low noise: Vno = 98dBV (typ.)
Weight: 0.14 g (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
