Analog signal input. Conversion range is 0.5 V
0.68 V
Positive reference voltage input. Operating range of
this voltage is 0.75V to V
bypassed with a 10 µF tantalum or aluminum
electrolytic capacitor and a 0.1 µF ceramic chip
capacitor.
CMOS/TTL compatible digital input that, when low,
enables the digital outputs of the ADC08351. When
high, the outputs are in a high impedance state.
CMOS/TTL compatible digital clock input. V
sampled on the falling edge of CLK input.
CMOS/TTL compatible digital input that, when high,
puts the ADC08351 into the power down mode,
where it consumes minimal power. When this pin is
low, the ADC08351 is in the normal operating
mode.
Conversion data digital output pins. D0 is the LSB,
D7 is the MSB. Valid data is output just after the
rising edge of the CLK input. These pins are
enabled by bringing the OE pin low.
