Datel ADC-304
ADC-304 is an 8-bit, 20MHz analog-to- Another novel feature of the ADC-304 is its digital flash converter. The ADC-304 offers many user-selectable output coding. The MINV and LINV performance features not obtainable from other pins allow selection of binary, complementary flash A/D’s.FEATURES
● 8-bit resolution● 20MHz conversion rate
● ±1/2LSB maximum nonlinearity FOR NEW DESIGNS Datel’s binary, and if external offset circuitry is used for Key reatures include a low power dissipation bipolar inputs, offset binary, two’s complement and of 375mW and TTL-compatible outputs. A wide complementary two’s complement coding. analog input bandwidth of 8MHz (–3dB) allows The ADC-304 is supplied in a 28-pin plastic operation without the need of a sample-hold. Also, DIP or a 28-pin plastic SOP package. Operating single +5V supply operation is obtainable with an temperature range is –20 to +75°C. Storage input range of +3 to +5V, eliminating the need for temperature range is –55 to +150°C. an additional power supply. A 0 to –2V input range is available with ±5V supply operation.
