19-1101; Rev 0; 6/96 KIT ATION EVALU BLE A IL A V A 8-Bit, 150Msps Flash ADC ____________________________Features o o o o o o _______________General Description 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-patible 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-patible 300Msps MAX1125 is available.
