TD62783APG,TD62783AFG: 8 ch High-Voltage Source Driver Bipolar (BJT) Transistor Array 8 NPN

The CA3080 and CA3080A types are Gatable-Gain Blocks which utilize the unique operational-transconductance- amplifier (OTA) concept described in Application Note AN6668, “Applications of the CA3080 and CA3080A High- Performance Operational Transconductance Amplifiers”.
The CA3080 and CA3080A types have differential input and a single-ended, push-pull, class A out-put. In addition, these types have an amplifier bias input which may be used either for gating or for linear gain control. These types also have a high output impedance and their transconductance (gM) is directly proportional to the amplifier bias current (IABC).
The CA3080 and CA3080A types are notable for their excellent slew rate (50V/μs), which makes them especially useful for multiplexer and fast unity-gain voltage followers. These types are espe-cially applicable for multiplexer applications because power is consumed only when the devices are in the “ON” channel state.
The CA3080A’s characteristics are specifically controlled for applications such as sample-hold, gain-control, multiplexing, etc.

Notes on Contents

1. Equivalent Circuits
The equivalent circuit diagrams may be simplified or some parts of them may be omitted for ex-planatory purposes.
2. Test Circuits
Components in the test circuits are used only to obtain and confirm the device characteristics. These components and circuits are not guaranteed to prevent malfunction or failure from occurring in the application equipment.

Precautions for Using 

This IC does not integrate protection circuits such as overcurrent and overvoltage protectors.
Thus, if excess current or voltage is applied to the IC, the IC may be damaged. Please design the IC so that excess current or voltage will not be applied to the IC.
Utmost care is necessary in the design of the output line, COMMON and GND line since IC may be destroyed due to short−circuit between outputs, air contamination fault, or fault by improper grounding.
