ADC0820  
8-Bit High Speed µP Compatible A/D Converter with  
Track/Hold Function  
General Description  
Features  
n Built-in track-and-hold function  
n No missing codes  
By using  
a half-flash conversion technique, the 8-bit  
ADC0820 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.  
n No external clocking  
n Single supply — 5 VDC  
n Easy interface to all microprocessors, or operates  
stand-alone  
n Latched TRI-STATE® output  
n Logic inputs and outputs meet both MOS and T2L  
voltage level specifications  
The input to the ADC0820 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 has  
been designed to appear as a memory location or I/O port  
without the need for external interfacing logic.  
n Operates ratiometrically or with any reference value  
equal to or less than VCC  
n 0V to 5V analog input voltage range with single 5V  
supply  
Key Specifications  
n No zero or full-scale adjust required  
n Overflow output available for cascading  
n 0.3" standard width 20-pin DIP  
n 20-pin molded chip carrier package  
n 20-pin small outline package  
n Resolution  
8 Bits  
2.5 µs Max (RD Mode)  
1.5 µs Max (WR-RD Mode)  
75 mW Max
