The MAX157/MAX159 low-power, 10-bit analog-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 successive-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 throughput rates, the 0.2µA automatic shutdown further reduces power consumption.

The MAX157 provides 2-channel, single-ended operation 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, combined 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 requirements. For pin-compatible 12-bit upgrades, see the MAX144/MAX145 data sheet.
