+2.7V, Low-Power,  
12-Bit Serial ADCs in 8-Pin SO  
__________________General Description  
________________________________Features  
♦ Single-Supply Operation:  
+2.7V to +3.6V (MAX1240)  
+2.7V to +5.25V (MAX1241)  
The MAX1240/MAX1241 low-power, 12-bit analog-to-  
digital converters (ADCs) are 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  
successive-approximation ADC, a fast track/hold  
(1.5µs), an on-chip clock, and a high-speed, 3-wire ser-  
ial interface.  
♦ 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  
66µW (1ksps, MAX1241)  
DD  
5µW (power-down mode)  
73ksps maximum sampling speed. A 2µA shutdown  
mode reduces power at slower throughput rates.  
♦ Internal Track/Hold  
The MAX1240 has an internal 2.5V reference, while the  
MAX1241 requires an external reference. The MAX1241  
♦ SPI/QSPI/MICROWIRE 3-Wire Serial Interface  
♦ Internal Clock  
accepts signals from 0V to V  
, and the reference  
REF  
Ordering Information  
input range includes the positive supply rail. An exter-  
nal clock accesses data from the 3-wire interface,  
which connects directly to standard microcontroller I/O  
ports. The interface is compatible with SPI™, QSPI™,  
and MICROWIRE™.

Excellent AC characteristics and very low power com-  
bined with ease of use and small package size make  
these converters ideal for remote-sensor and data-  
acquisition applications, or for other circuits with  
demanding power consumption and space require-  
ments. The MAX1240/MAX1241 are available in 8-pin  
PDIP and SO packages.
