♦ +2.7V to +5.25V Single-Supply Operation

♦ 10-Bit Resolution

The MAX1242/MAX1243 are low-power, 10-bit analog-

to-digital converters (ADCs) available in 8-pin pack-

a g e s . The y op e ra te with a s ing le +2.7V to +5.25V

supply and feature a 7.5µs successive-approximation

ADC, a fast track/hold (1.5µs), an on-chip clock, and a

high-speed, 3-wire serial interface.

♦ Internal 2.5V Reference (MAX1242)

♦ Small Footprint: 8-Pin DIP and SO Packages

♦ Low Power: 3.7mW (73ksps, MAX1242)

3mW (73ksps, MAX1243)

Power consumption is only 3mW (V

= 3V) at the

73ksps maximum sampling speed. A 2µA shutdown

mode reduces power at slower throughput rates.

66µW (1ksps, MAX1243)

5µW (power-down mode)

The MAX1242 has an internal 2.5V reference, while the

MAX1243 requires an external reference. The MAX1243

♦ Internal Track/Hold

accepts signals from 0V to V

, and the reference

REF

♦ SPI™/QSPI™/Microwire™ 3-Wire Serial Interface

input range includes the positive supply rail. An exter-

na l c loc k a c c e s s e s d a ta from the 3-wire inte rfa c e ,

which connects directly to standard microcontroller I/O

ports. The interface is compatible with SPI™, QSPI™,

and Microwire™.

♦ Pin-Compatible 12-Bit Upgrades:

MAX1240/MAX1241

_________________Ord e rin g In fo rm a t io n

Excellent AC characteristics and very low power com-

bined with ease of use and small package size make

these converters ideal for remote-sensor and data-

a c q uis ition a p p lic a tions , or for othe r c irc uits with

demanding power consumption and space require-

ments. The MAX1242/MAX1243 are available in 8-pin

DIP and SO packages.
