General Description Features
The MAX151 isa high-speed, f,'i1i',ygttocui'ies microproces- t 10-Bit Resolution and Accuracy
sor (PP) compatible IO-bit Analog-to- igital Converter .
(ADC) with Track-and-Hold (T/H). Half-flash techniques t 11LSB Total Unadlusted Error
allow a typical conversion time of ISPs with a Total . 2.5ps Max Conversion Time
Unadjusted Error (TUE) of i1 LSB (Max). The converter (0.5ps Input Acquisition Time)
It/ds/pt/is'." analog input voltage range and uses t 300kHz Sampling Rate
The MAX151 internally tracks and holds the analog t Internal 60pem/ C Reference
