    產(chǎn)品信息

    描述 By using a half-flash conversion technique, the 8-bit ADC0820-N CMOS A/D offers a 1.5 μs conversion time and dissipates only 75 mW of power. The half-flash technique consists of 32 comparators, a most significant 4-bit ADC and a least significant 4-bit ADC.The input to the ADC0820-N is tracked and held by the input sampling circuitry eliminating the need for an external sample-and-hold for signals moving at less than 100 mV/μs.For ease of interface to microprocessors, the ADC0820-N has been designed to appear as a memory location or I/O port without the need for external interfacing logic.特性Built-In Track-and-Hold Function No Missing Codes No External Clocking Single Supply—5 VDC Easy Interface to All Microprocessors, or Operates Stand-Alone Latched TRI-STATE Output Logic Inputs and Outputs Meet Both MOS and T2L Voltage Level Specifications Operates Ratiometrically or with any Reference Value Equal to or Less than VCC 0V to 5V Analog Input Voltage Range with Single 5V Supply No Zero or Full-Scale Adjust Required Overflow Output Available for Cascading 0.3 in.
