The MAX1240/MAX1241 are low-power, 12-bit analog-  
to-digital converters (ADCs) available in 8-pin pack-  
ages. The MAX1240 operates with a single +2.7V to  
+3.6V supply, and the MAX1241 operates with a single  
+2.7V to +5.25V supply. Both devices feature a 7.5µs  
s uc c e s s ive -a p p roxima tion ADC, a fa s t tra c k/hold  
(1.5µs), an on-chip clock, and a high-speed, 3-wire ser-  
ial interface.  
♦ Single-Supply Operation:  
+2.7V to +3.6V (MAX1240)  
+2.7V to +5.25V (MAX1241)  
♦ 12-Bit Resolution  
♦ Internal 2.5V Reference (MAX1240)  
♦ Small Footprint: 8-Pin DIP/SO Packages  
♦ Low Power: 3.7µW (73ksps, MAX1240)  
3mW (73ksps, MAX1241)  
Power consumption is only 37mW (V  
= 3V) at the  
DD  
73ksps maximum sampling speed. A 2µA shutdown  
mode reduces power at slower throughput rates.  
66µW (1ksps, MAX1241)  
5µW (power-down mode)  
The MAX1240 has an internal 2.5V reference, while the  
MAX1241 requires an external reference. The MAX1241  
♦ Internal Track/Hold  
♦ SPI/QSPI/MICROWIRE 3-Wire Serial Interface  
♦ Internal Clock  
accepts signals from 0V to V  
, and the reference  
REF  
input range includes the positive supply rail. An exter-  
na l c loc k a c c e s s e s d a ta from the 3-wire inte rfa c e ,  
which connects directly to standard microcontroller I/O  
ports. The interface is compatible with SPI™, QSPI™,  
and MICROWIRE™.
