with
conventional practice of specifying performance at a
single sample rate only, the
a high-speed serial interface. Unlike the
Variable Power Management
Single Power Supply with 2.7V - 5.25V Range
ADC104S021/ADC104S021Q is fully specified over a
sample rate range of 50 ksps to 200 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 four input
signals at inputs IN1 through IN4.
ADC104S021Q is AEC-Q100 Grade 3 Qualified
and is Manufactured on an Automotive Grade
Flow
•
Meets AEC-Q100-011 C2 CDM Classification
APPLICATIONS
The output serial data is straight binary, and is
compatible with several standards, such as SPI™,
QSPI™, MICROWIRE, and many common DSP
serial interfaces.

Automotive
The ADC104S021/ADC104S021Q operates with a
single supply, that can range from +2.7V to +5.25V.
Normal power consumption using a +3V or +5V
supply is 1.94 mW and 6.9 mW, respectively. The
power-down feature reduces the power consumption
to just 0.12 µW using a +3V supply, or 0.47 µW using
a +5V supply.
