TA2131FN General Description
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. A2131FN 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 are added or 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- requency component reaches a high level, the boost gain is controlled to main a low distortion.
The features of TA2131FN can be summarized as (1)low current consumption: ICCQ (VCC1) = 0.55 mA(typ.) ICCQ (VCC2) = 0.20 mA(typ.); (2)output power : Po = 8mW(typ.)(VCC1 = 2.8V, VCC2 = 1.2 V, = 1 kHZ, THD = 10%, RL = 16); (3)low noise : Vno = -102 dBV(typ.); (4)built-in low-pass boost (with AGC); (5)I/O pin for beep sound; (6)outstanding ripple rejection ratio; (7)built-in power mute; (8)built-in power ON/OFF switch; (9)operating supply voltage range (Ta = 25°C) : VCC1=1.8~4.5V VCC2 =0.9~4.5V.
The absolute maximum ratings of TA2131FN are (1)supply voltage VCC: 4.5V; (2)output current lo(peak): 100mA; (3)power dissipation PD (Note: derated above Ta = 25°C in the proportion of 4mW/°C):500 mW; (4)operating temperature Topr: -25~75°C; (5)storage temperature Tstg: -55~150°C.
