ADC088S052
8-Channel, 200 kSPS to 500 kSPS, 8-Bit A/D Converter
General Description
The ADC088S052 is a low-power, eight-channel CMOS 8-bit
analog-to-digital converter specified for conversion through-
put rates of 200 kSPS to 500 kSPS. The converter is based
on a successive-approximation register architecture with an
internal track-and-hold circuit. It can be configured to accept
up to eight input signals at inputs IN0 through IN7.
The output serial data is straight binary and is compatible
www.DataSheet4U.cwoimth several standards, such as SPI™, QSPI™, MICROW-
IRE™, and many common DSP serial interfaces.
The ADC088S052 may be operated with independent ana-
log and digital supplies. The analog supply (VA) can range
from +2.7V to +5.25V, and the digital supply (VD) can range
from +2.7V to VA. Normal power consumption using a +3V or
+5V supply is 1.2 mW and 6.5 mW, respectively. The power-
down feature reduces the power consumption to 0.03 µW
using a +3V supply and 0.15 µW using a +5V supply.
The ADC088S052 is packaged in a 16-lead TSSOP pack-
age. Operation over the extended industrial temperature
range of −40˚C to +105˚C is guaranteed.
