Audio Frequency Amplifier Applications
Low Noise Audio Frequency Applications
· Small package.
· High voltage: VCEO = −50 V (min)
· High hFE: hFE = 70~400
· Excellent hFE linearity: hFE (IC = −0.1 mA)/hFE (IC = −2 mA) = 0.95 (typ.)
· Low noise: NF = 0.2dB (typ.), 3dB (max)
· Complementary to 2SC2458 (L).
