TCA 2465 Q67000-A8109 P-SIP-9-1
TCA 2465 G Q67000-A8334 P-DSO-20-6
Description
The IC contains two identical op amps , eac h su pply ing a hig h outp ut cu rre nt of 2 .5 A at
supply voltages between ± 3V and
± 20 V. Internal compensation permits negative
feedback of the amplifiers up to a min. of 20 dB. Both amplifiers can be disconnected at
V
≥ 2 V via an inhibit input. Integrated protective circuits protect the outputs against
8
V
short-circuit to +
and – VS and prevent thermal overloading of the IC. TCA 2465 G
S
comes in a special surface -mounted power package si milar to P-DSO-20 and delivers
twice 2.0 A output peak curr ent.
