Description

The ADC-228 combines analog front-end circuitry and a flash A/D converter to digitize high-speed analog signals at a rate of 20 million samples per second.  The ADC-228 contains an 8-bit, 20MHz, flash A/D, a wideband analog input buffer, a precision voltage reference, temperature compensation circuitry, reference trims, and a three-state output buffer in a 24-pin package.

The ADC-228 offers significant savings by combining all of the circuitry in a single package.  Valuable board real estate is saved, and design time and manufacturing costs are reduced. The ADC-228 is housed in a 24-pin ceramic DDIP package and is available in the commercial, 0 to +70°C, or military, 55 to +125°C, temperature ranges.  A MIL-STD-883 version is also available.  Operation is from ±15V and +5V power supplies.
