High-speed Buffer Amplifier for CCD Image Sensor
CXA3741AUR
Description
The CXA3741UR is a high-speed buffer amplifier IC with built-in switches.
(Applications: CCD image sensor output buffers, digital still cameras, camcorders, other general buffers)
Features
Power consumption: 26 mW (typ.)
(IDRV = 50μA (220kΩ when VCC = 15V), ISF current = 0, during no signal)
Push-pull output
High-speed response: 500 V/μs (IDRV = 50μA (220kΩ when VCC = 15V), CL = 20pF)
Internal sink current mode for CCD source follower output. Settable by external resistance RISF
Sink current and drive current with each built-in switch. Each current value can be set by an external
resistance.
