Description
The IC contains two identical op amps, each supplying a high output current of 2.5 A at
supply voltages between ± 3 V and ± 20 V. Internal compensation permits negative
feedback of the amplifiers up to a min. of 20 dB. Both amplifiers can be disconnected at
V8 ≥ 2 V via an inhibit input. Integrated protective circuits protect the outputs against
short-circuit to + VS and – VS and prevent thermal overloading of the IC. TCA 2465 G
comes in a special surface-mounted power package similar to P-DSO-20 and delivers
twice 2.0 A output peak current.
