+2.7V, Low-Power, 2-Channel,
108ksps, Serial 10-Bit ADCs in 8-Pin µMAX
General Description
The MAX157/MAX159 low-power, 10-bit analog-to-digi-
tal 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.
Power consumption is only 3.2mW (VDD = +3.6V) at the
maximum sampling rate of 108ksps. At slower through-
put rates, the 0.2µA automatic shutdown further
reduces power consumption.
The MAX157 provides 2-channel, single-ended opera-
tion and accepts input signals from 0 to VREF. The
MAX159 accepts pseudo-differential inputs ranging
from 0 to VREF. An external clock accesses data
through the 3-wire serial interface, which is SPI™,
QSPI™, and MICROWIRE™ compatible.
Excellent dynamic performance and low power, com-
bined with ease of use and a small package size, make
these converters ideal for battery-powered and data
acquisition applications, or for other circuits with
demanding power-consumption and space require-
ments. For pin-compatible 12-bit upgrades, see the
MAX144/MAX145 data sheet.
