19-1857; Rev 0; 11/00

Single-Supply, Low-Power,

2-Channel, Serial 8-Bit ADCs

General Description

Features

The MAX1117/MAX1118/MAX1119 low-power, 8-bit,

dual-channel, analog-to-digital converters (ADCs) fea-

ture an internal track/hold (T/H) voltage reference

(MAX1117/MAX1119), clock, and serial interface. The

MAX1118 is specified from +2.7V to +5.5V and con-

sumes only 135µA at 100ksps. The MAX1117 is speci-

fied from +2.7V to +3.6V, and the MAX1119 is specified

from +4.5V to +5.5V, each consumes only 175µA at

100ksps.

♦ Single Supply

♦ Internal Track/Hold: 100kHz Sampling Rate

♦ Internal Reference

+2.048V (MAX1117)

+4.096V (MAX1119)

The full-scale analog input range is determined by the

internal reference of +2.048V (MAX1117) or +4.096V

(MAX1119), or by an externally applied reference rang-

♦ Reference Input Range: 0 to V

(MAX1118)

♦ SPI/QSPI/MICROWIRE-Compatible Serial Interface

♦ Small 8-Pin SOT23 Package

ing from +1V to V

(MAX1118). All devices feature an

automatic shutdown mode that reduces supply current

to <1µA when the device is not in use. The 3-wire serial

interface directly connects to SPI™, QSPI™, and

MICROWIRE™ devices without external logic.

Conversions up to 100ksps are performed using an

internal clock.

♦ Automatic Power-Down

♦ Analog Input Range: 0 to V

♦ Low Power

The MAX1117/MAX1118/MAX1119 are available in an

8-pin SOT23 package with a footprint that is only 11%

of an 8-pin plastic DIP.
