MAX1106EUB+T
Single-Supply, Low-Power, Serial 8-Bit ADCs
General Description
The MAX1106/MAX1107 low-power, 8-bit, single-channel,
analog-to-digital converters (ADCs) feature an internal
track/hold (T/H), voltage reference, clock, and serial inter-
face. The MAX1106 is specified from +2.7V to +3.6V and
consumes only 96μA. The MAX1107 is specified from
+4.5V to +5.5V and consumes only 107μA. The analog
inputs are pin-configurable, allowing unipolar and single-
ended or differential operation.
The full-scale analog input range is determined by the
internal reference of +2.048V (MAX1106) or +4.096V
(MAX1107), or by an externally applied reference rang-
ing from 1V to VDD. The MAX1106/MAX1107 also feature
a pin-selectable power-down mode that reduces power
consumption to 0.5μA 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 25ksps are performed using the inter-
nal clock.
The MAX1106/MAX1107 are available in a 10-pin μMAXackage with a footprint that is just 20% of an
8-pin plastic DIP.
