+2.7V, Low-Power, 2-Channel, 108ksps,

Serial 12-Bit ADCs in 8-Pin µMAX

General Description

Features

The MAX144/MAX145 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 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 (MAX144) One

Pseudo-Differential Channel (MAX145)

♦ Low Power

0.9mA (108ksps, +3V Supply)

100µA (10ksps, +3V Supply)

10µA (1ksps, +3V Supply)

0.2µA (Power-Down Mode)

Power consumption is only 3.2mW (V

= +3.6V) at the

maximum sampling rate of 108ksps. At slower through-

put rates, the automatic shutdown (0.2µA) further

reduces power consumption.

♦ Internal Track/Hold

♦ 108ksps Sampling Rate

The MAX144 provides 2-channel, single-ended opera-

tion and accepts input signals from 0 to V

. The

REF

♦ SPI/QSPI/MICROWIRE-Compatible 3-Wire Serial

MAX145 accepts pseudo-differential inputs ranging

from 0 to V . An external clock accesses data-

Interface

REF

through the 3-wire serial interface, which is SPI™,

QSPI™, and MICROWIRE™-compatible.

♦ Space-Saving 8-Pin µMAX Package

♦ Pin-Compatible 10-Bit Versions Available

Excellent dynamic performance and low power, com-

bined 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 require-

ments. For pin-compatible 10-bit ADCs, see the

MAX157 and MAX159 data sheets.
