UA9708

The UA9708 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 UA9708 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 UA9708 are: (1)MPU compatible; (2)excellent linearity over full temperature range ±0.2% max; (3)typical 300s conversion time per channel; (4)wide dynamic range includes ground; (5)auto-zero and full-scale correction capability; (6)ratiometric conversion capability; (7)single-supply operation; (8)TTL compatible.

The absolute maximum ratings of the UA9708 are: (1)supply voltage: 18V; (2)comparator output: -0.3V to +18V; (3)analog input range: -0.3V to +30V; (4)digital input range: -0.3V to +30V; (5)output sink current: 10mA; (6)storage temperature range: -65 to +150; (7)continuous total dissipation: 900mW.
