P-Channel Amplifier
DESCRIPTION
The J270/SST270 Series is an all-purpose amplifier for
designs requiring P-channel operation. These devices feature
high gain, low noise and tight V
GS(OFF)
limits for simple circuit
design. They are available in low-cost SOT-23 and TO-92
packages and are fully compatible with automatic insertion
techniques.
