DESCRIPTION
The ADC088S102 is a low-power, eight-channel
CMOS 8-bit analog-to-digital converter specified for
conversion throughput rates of 500 kSPS to 1 MSPS.
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 with several standards, such as SPI,
QSPI, MICROWIRE, and many common DSP serial
interfaces.
The ADC088S102 may be operated with independent
analog and digital supplies. The analog supply (V_A)
can range from +2.7V to +5.25V, and the digital
supply (V_D) can range from +2.7V to V_A. Normal
power consumption using a +3V or +5V supply is 1.8
mW and 8.0 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 ADC088S102 is packaged in a 16-lead TSSOP
package. Operation is specified over the extended
industrial temperature range of −40°C to +105°C.
