The MAX144/MAX145 low-p owe r, 12-b it a na log -to-

digital converters (ADCs) are available in 8-pin µMAX

and DIP packages. Both devices operate with a single

+2.7V to +5.25V supply and feature a 7.4µs succes-

sive-approximation ADC, automatic power-down, fast

wake-up (2.5µs), an on-chip clock, and a high-speed,

3-wire serial interface.

♦ Single-Supply Operation (+2.7V to +5.25V)

♦ Two Single-Ended Channels (MAX144)

One Pseudo-Differential Channel (MAX145)

♦ Low Power

10µA (1ksps, +3V Supply)

0.2µA (Power-Down Mode)

Power consumption is only 3.2mW (V = +3.6V) at the

maximum sampling rate of 108ksps. At slower through-

p ut ra te s , the a utoma tic s hutd own (0.2µA) furthe r

reduces power consumption.
