8-Bit, 150Msps Flash ADC
_______________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-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 con-
version rates, the pin-compatible 300Msps MAX1125 is
available.
