Description

Datel's ADC-304 is an 8-bit, 20MHz analog-to-digital flash converter.  The ADC-304 offers many performance features not obtainable from other flash A/D's. Key reatures include a low power dissipation of 375mW and TTL-compatible outputs.  A wide analog input bandwidth of 8MHz (3dB) allows operation without the need of a samplehold.  Also, single +5V supply operation is obtainable with an input range of +3 to +5V, eliminating the need for an additional power supply.  A 0 to 2V input range is available with ±5V supply operation.

Another novel feature of the ADC-304 is its user-selectable output coding.  The MINV and LINV pins allow selection of binary, complementary binary, and if external offset circuitry is used for bipolar inputs, offset binary, two's complement and complementary two's complement coding. The ADC-304 is supplied in a 28-pin plastic DIP or a 28-pin plastic SOP package. Operating temperature range is 20 to +75°C.  Storage temperature range is 55 to +150°C.
