Fe a t u re s

The MAX157/MAX159 low-power, 10-bit analog-to-digi-

tal converters (ADCs) are available in 8-pin µMAX and

DIP p a c ka g e s . Both d e vic e s op e ra te with a s ing le

+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 (MAX157)

Single Pseudo-Differential Channel (MAX159)

♦ Low Power

<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 0.2µA a utoma tic s hutd own furthe r

reduces power consumption.
