12-Bit Resolution  
The MAX187/MAX189 serial 12-bit analog-to-digital  
converters (ADCs) operate from a single +5V supply  
and accept a 0V to 5V analog input. Both parts feature  
a n 8.5µs s uc c e s s ive -a p p roxima tion ADC, a fa s t  
track/hold (1.5µs), an on-chip clock, and a high-speed  
3-wire serial interface.

the interface, which communicates without external  
hardware to most digital signal processors and micro-

_________________Ord e rin g In fo rm a t io n  
The MAX187 has an on-chip buffered reference, and  
the MAX189 requires an external reference. Both the  
MAX187 and MAX189 save space with 8-pin DIP and  
16-pin SO packages. Power consumption is 7.5mW  
and reduces to only 10µW in shutdown.

Excellent AC characteristics and very low power con-  
sumption combined with ease of use and small pack-  
age size make these converters ideal for remote DSP  
and sensor applications, or for circuits where power  
consumption and space are crucial.
