  • Available in 0.3" DIP or Wide SO Packages

The MAX183/184/185 are 12-bit, high-speed, BiCMOS, analog-to-digital converters (ADCs) that consume only 90mW of power while performing con­versions in as little as 3µs. All three ADCs perform identically, except for conversion time: MAX183 - 3µs, MAX184- 5µs, MAX185 - 10µs.

The MAX1.83/184/185 require an external -5V reference. A buffered reference input minimizes reference-current requirements and allows a single reference to drive sev­eral 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 (µP) clock.

Analog input range is pin-selectable for 0 to +5V, 0 to + 1 0V, or ±5V, 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 µPs.

The MAX183/184/185 are available in space-saving, 24-pin narrow plastic DIP, CERDIP, and wide SO packages.
