W55AD808 Data Sheet
1 General Description
W55AD808, a low cost 8-bit ADC with 8 input channels. Each channel can be defined
as digital or analog input mode independently. In analog input mode, this channel can
accept an analog input range from 0V ~ VREF and convert it into a 10-bit digital data format
(with 8-bit significant digits). W55AD808 provides a serial interface for host CPU to control it.
Beside analog input mode, all input pins can be defined as digital input mode; host CPU can
monitor them by the serial interface.
2 Features
Operating voltage: 2.7V ~ 5.5V.
Guarantee 8-bit A/D resolution.
8 analog input channels.
Each channel can be independently programmed to a digital input mode.
50KHz conversion rate.
10-bit ADC with 8-bit significant digits.
Operation current: 0.5mA ~ 1mA.
Stand-by current: <0.5uA @ 4.5V.
Auto entry power-down mode.
Less external components.
