LINEAR INTEGRATED CIRCUIT
DUAL PRE-AMPLIFIER
ꢀ
FEATURES
* Dual pre amplifier for cat or home stereo use.
* High voltage gain: GVO = 100dB (Typ.) at f= 1kHz.
* Excellent channel separation and high ripple rejection
: CS = 65dB(Typ.)
(f = 10kHz, RG = 2.2kΩ, VOUT= 0dBm)
: RR = 50dB(Typ.)
* Low noise: VNI = 1.0µV(Typ.) at RG = 2.2kΩ, Bw =20Hz~20kHz
* Wide operating supply voltage range: VCC = 6~16V (Ta = 25℃)
SIP-9
*Pb-free plating product number: A6225L
