Overview

The MAX144/MAX14585AEVB+T low-power, 12-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 automatic shutdown (0.2μA) further reduces power consumption. The MAX144 provides 2-channel, single-ended operation and accepts input signals from 0 to VREF. The MAX14585AEVB+T 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 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 10-bit ADCs, see the MAX157 and MAX159 data sheets.
