Description

DATEL's ADC-305 is an 8-bit, 20MHz sampling, CMOS, subranging (two-pass) A/D converter. It processes signals at speeds comparable to a full flash converter by using a sub-ranging conversion technique with multiple comparator blocks, each containing a sample and hold amplifier.

The ADC-305 features CMOS low power dissipation (60mW typical) and a wide 18MHz (1dB) input signal bandwidth. The ADC-305-1 is packaged in 400 mil 24-pin DIP and the ADC-305-3 in 300 mil 24-pin SOP . Other features are CMOS compatible input logic, 3-state TTL compatible output logic, +5V single power operation, self bias mode and low cost.
