General Description
The MAX183/184/185 are 12-bit, high-speed,
BiCMOS, analog-to-digital converters (ADCs) that
consume only 90mW of power while performing con-
versions in as little as Sus. All three ADCs perform
identically, except for conversion time: MAX183 - Sps,
MAX184 - Sus. MAX185 - lows.
The MAX183/184/185 require an external -5V reference.
A buffered reference input minimizes reference-current
requirements and allows a single reference to drive sev-
eral ADCs. External reference specs can be chosen to
suit the accuracy of the application. The ADC clock can
be driven from either a crystal or an external clock source,
such as a microprocessor (WP) clock.
Analog input range is pin-selectable for O to +5V, 0 to
+10V, or 15V, making the ADCs ideal for data acquisition
and analog input/output cards. A high-speed digital
interface (100ns data access time) with three-state data
outputs is compatible with most “PS.
The MAX183/184/185 are available in space-saving, 24-pin
narrow plastic DIP, CERDIP, and wide so packages.
