Low Noise Audio Amplifier Applications
Unit: mm
• Recommended for first stages of EQ and M.C. head amplifiers.
• High |Yfs|: |Yfs| = 22 mS (typ.) (VDS = 10 V, VGS = 0, IDSS = 3 mA)
• High breakdown voltage: VGDS = −40 V
• Low noise: En = 0.95 nV/Hz1/2 (typ.)
(VDS = 10 V, ID = 1 mA, f = 1 kHz)
• High input impedance: IGSS = −1 nA (max) (VGS = −30 V)

Note:
Using continuously under heavy loads (e.g. the application of

high temperature/current/voltage and the significant change in
temperature, etc.) may cause this product to decrease in the

absolute maximum ratings.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test
report and estimated failure rate, etc).
