Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

The MAX1114 is a monolithic, flash analog-to-digital converter (ADC) that can digitize a 2V analog input signal into 8-bit digital words at a typical 150Msps update rate.

For most applications, no external sample-and-hold is required for accurate conversion due to the device's narrow aperture time, wide bandwidth, and low input capacitance. A single standard -5.2V power supply is required to operate the MAX1114, with nominal 2.2W power dissipation. A special decoding scheme reduces metastable errors to 1LSB.

The part is packaged in a 42-pin ceramic sidebraze that is pin-compatible with the CX20116 and CXA1396D. The surface-mount 44-pin CERQUAD allows access to additional reference ladder taps, an overrange bit, and a data-ready output. For higher conversion rates, the pin-compatible 300Msps MAX1125 is available.
