Dual Power Operational Amplifier
TCA 2465
Overview Bipolar IC
Features
• High output peak current of twice 2.5 A
• Twice 2.0 A output peak current for TCA 2465 G
• Large supply voltage range up to 42 V
• High slew rate of 2 V/µs
• Outputs fully protected (DC short-circuit proof for
V
P-SIP-9-1
for P-DSO-20-6
up to 18 V;
S
V
up to 14 V)
S
P-SIP-9-1
• Thermal overload protection
• Inhibit input enables “tristate” outputs
• Integrated clamp diodes

Type Ordering Code Package
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.
