UAF1780

The UAF1780 is a single slope 8-bit, 6-channel ADC subsystem that provides all of the necessary analog functions for a microprocessor-based data control system. The UAF1780 uses an external microprocessor system to provide the necessary addressing, timing and counting functions and includes a 1 of 8 decoder and a comparator on a single monolithic chip.

The features of the UAF1780 are: (1)MPU compatible; (1)low power dissipation; (2)all inputs are operational with control signals higher than Vcc; (3)all inputs withstand voltages lower than ground; (4)high output currents; (5)protection of output transistors; (6)the outputs can withstand voltages lower than ground; (7)withstand on Vcc spikes up to (60 V, 10ms); (8)differential inputs.

The absolute maximum ratings of the UAF1780 are: (1)supply voltage: +35V; (2)input voltage: 30 to +55V; (3)output current: internally limited; (4)current in DC/DC converter inductance: 0.4A; (5)total power dissipation: internally limited; (6)operating free-air temperature range: -40 to +85; (7)junction temperature: +150.
