GENERAL DESCRIPTION  
The MP8820 is a precision 1.6 MHz sampling 7-bit plus sign  
Analog-to-DigitalConverter with an eight channel input mux and  
µP interface. The device has internal circuitry which receives  
the user supplied reference voltages VREF(+) and VREF(–), and  
to within 0.5 V of the supply rails, giving the MP8820 a wide  
range over which the effective channel gain can be adjusted.  
The MP8820 uses a two-step flash conversion technique.  
The first section determines the sign and the 3 MSBs while the  
second segment converts the 4 LSBs. The ADC conversion be-  
gins when WR goes low and the data is valid 500 ns after the  
rising edge of WR. The MP8820 operates from a single 5V sup-  
ply and consumes only 175mW of power.  
generates the ADC reference voltages VMID (VREF(+)  
V
REF(–)). Since VREF(+) is internally buffered and VREF(–) is gen-  
erallyground, thisstructureallowstheusertoeasilygeneratean  
input range biased about a user-supplied VMID from a grounded  
reference source.  
Specified for operation over the industrial (–40 to +85°C)  
temperature range, the MP8820 is available in Surface Mount  
(SOIC) and Shrunk Small Outline (SSOP) packages.  
The internal ADC reference voltages are capable of swinging
