TC35095P

The TC35095P is a monolithic CMOS 8 bit successive approximation A/D coverter with serial I/O and 8 channel multiplex inputs. Conversion start when CS is set low and start bit (L level) and channel select bit(three bits) are given to serial input DI. In case that SE is high, as soon as the conversion starts a start bit (L level) appears at serial output DO and 8 bit conversion data (MSB first) and a stop bit (H level) follow continuously. In case that SH is low, after the conversion is completed a start bit, 8 bit conversion data (LSB first) and a stop bit appear at DO. The TC35095P has features of high speed, high accuracy and microprocessor compatible I/O hich make the device well suited to a broad application field such as process and achine control and automotive equipment.

The features of TC35095P can be summarized as (1)high accuracy ±3/4LSB MAX; (2)high speed conversion. 35sec MAX @fCp=400kHz; (3)single power supply: 5V±10%; (4)low power consumption: 5mW MAX @Ta=25°C; (5)serial I/O; (6)8 channel analog multiplex input; (7)easy interface to all microprocessors; (8)3-scans output; (9)zero or full scale adjustment free .
