产品概述

The MAX144/MAX145 low-power, 12-bit analog-to-digitalconverters (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, fastwake-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 themaximum sampling rate of 108ksps. At slower throughputrates, the automatic shutdown (0.2µA) furtherreduces power consumption.

The MAX144 provides 2-channel, single-ended operationand accepts input signals from 0 to VREF. TheMAX145 accepts pseudo-differential inputs rangingfrom 0 to VREF. An external clock accesses data-throughthe 3-wire serial interface, which is SPI™,QSPI™, and MICROWIRE™-compatible.

Excellent dynamic performance and low power, combinedwith ease of use and small package size, makethese converters ideal for battery-powered and data-acquisitionapplications, or for other circuits withdemanding power-consumption and space requirements.For pin-compatible 10-bit ADCs, see theMAX157 and MAX159 data sheets.
