TECHNICAL DATA
Dual Independent Differential
Amplifier
The CA3054 consists of two independent differential amplifiers with associated
constant-current transistors on a common monolithic substrate. The six NPN
transistors which comprise the amplifiers are general purpose devices useful from
DC to 120 MHz.
The monolithic construction of the CA3054 provides close electrical and
thermal matching of the amplifiers which makes this device particularly useful in
dual channel applications where matched performance of the two channels is
required.
• Two Differential Amplifiers on a Common Substrate
• Independently Accessible Inputs and Outputs
