ADC0820CCN+

The ADC0820CCN+ is a CMOS high speed 8bit analogue to digital converter (ADC) with track/hold function in 20 pin DIP package. This high speed, microprocessor compatible 8bit analogue to digital converter uses a half flash technique to achieve conversion time of 1.4μS. A built-in track and hold function eliminates the need for an external track and hold for input skew rates up to 100mV/μS. The device easily interfaces with microprocessors by appearing as memory location or I/O port without need for external interfacing logic. Data outputs use latched, 3 state buffer circuitry to allow direct connection to a microprocessor data bus or system I/O port. An over flow output is also provided for cascading device to achieve higher resolution. It is used in high speed data acquisition, telecommunication and high speed servo loops.
