Single-Supply, Low-Power, Serial 8-Bit ADCs
General Description
The MAX1115/MAX1116 low-power, 8-bit, analog-to-
digital converters (ADCs) feature an internal track/hold
(T/H), voltage reference, VDD monitor, clock, and serial
interface. The MAX1115 is specified from +2.7V to
+5.5V, and the MAX1116 is specified from +4.5V to
+5.5V. Both parts consume only 175µA at 100ksps.
The full-scale analog input range is determined by the
internal reference of +2.048V (MAX1115) or +4.096V
(MAX1116). The MAX1115/MAX1116 also feature
AutoShutdown™ power-down mode which reduces
power consumption 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 per-
formed using an internal clock.
The MAX1115/MAX1116 are available in an 8-pin
SOT23 package with a footprint that is just 30% of an
8-pin SO.

supply is noisy, a 0.1µF capacitor in conjunction with a
10Ω series resistor can be connected to form a low-
pass filter.
