Reference Bottom Bias with internal pull down
resistor. Short to V
ladder. Bypass well if not grounded. See Section
2.0 for more information.
CMOS/TTL compatible Digital input that, when high,
puts the ADC1175-50 into a power-down mode
where total power consumption is typically less than
5 mW. With this pin low, the device is in the normal
operating mode.
CMOS/TTL compatible digital clock input. V
sampled on the falling edge of CLK input.
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 in a
high impedance mode when the PD pin is low.
Positive digital supply pin. Connect to a clean, quiet
voltage source of +5V. AV
a common source and be separately bypassed with
a 10 µF capacitor and a 0.1 µF ceramic chip
capacitor. See Section 4.0 for more information.
