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

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™.

Excellent AC characteristics and very low power com-

these converters ideal for remote-sensor and data-

demanding power consumption and space require-

ments. The MAX1240/MAX1241 are available in 8-pin
