ADA4800ACPZ-RL

ADA4800ACPZ-RL is a low-power, high-speed CCD buffer amplifier. This voltage buffer is integrated with an active load. This buffer is a low power, high speed, low noise, high slew rate, fast settling, and a fixed gain of 1 monolithic amplifier for charge-coupled device (CCD) applications. For CCD applications, the active load current source (IAL) can load the open source CCD sensor outputs and the buffer can drive the AFE load. The active current load can also be switched off, to use the device as just a unity gain buffer. The buffer consumes only 20mW of static power. In applications where power savings is critical, this device features a power save mode which further reduces the total current consumption. The buffer of the device employs a push-pull output stage architecture, providing drive current and maximum slew capability for both rising and falling signal transitions. It is used in applications such as CCD image sensor output buffers, digital still cameras, and camcorders.
