LT1057/LT1058
TYPICAL PERFORMANCE CHARACTERISTICS
APPLICATIONS INFORMATION
The LT1057 may be inserted directly in LF353, LF412,
LF442, TL072, TL082 and OP-215 sockets. The LT1058
plugs into LF347, LF444, TL074 and TL084 sockets. Of
course, all standard dual and quad bipolar op amps can
also be replaced by these devices.
