DESCRIPTION:

The 7820 is a microprocessor compatible 8-bit Analog-to-Digital Converter with a 0V to +5V input supply range with a single +5 Volt supply.

The 7820 incorporates internal sample-and-hold circuitry which eliminates the need for an external S/H for signals with slew rates less than 100 mV/µs.

The 7820 was designed to be easiliy interfaced with microprocessors, appearing as either a memory location or I/O port without the need for external interfacing. All outputs are latched and tri-state buffered.

FEATURES:

• 1.36 µs Conversion Time

• Built-in-Track-and-Hold Function

• No External Clock Required

• Tri-State Output Buffered

• Total Ionization Dose:

- > 50 krads (Si), depending upon space mission.

• Excellent Single Event Effects

- SEL > 80 MeV/mg/cm2

• Package:

- 20 pin Rad-Pak DIP
