Dual Power Operational Amplifier
Overview
Bipolar
IC
TCA 2465
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/
s
Outputs fully protected (DC short-circuit proof for
P-SIP-9-1
V
S
up to 18 V;
for P-DSO-20-6
V
S
up to 14 V)
Thermal overload protection
Inhibit input enables "tristate" outputs
Integrated clamp diodes
P-SIP-9-1
P-DSO-20-6
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
V
8
2 V via an inhibit input. Integrated protective circuits protect the outputs against
short-circuit to +
V
S
and
V
S
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.
