__________________General Desc ription
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
successive-approximation ADC, a fast track/hold
(1.5μs), an on-chip clock, and a high-speed, 3-wire ser-
ial interface.
Power consumption is only 37mW (V
DD
= 3V) at the
73ksps maximum sampling speed. A 2μA shutdown
mode reduces power at slower throughput rates.
The MAX1240 has an internal 2.5V reference, while the
MAX1241 requires an external reference. The MAX1241
accepts signals from 0V to V
REF
, and the reference
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
DIP and SO packages.
