FEATURES
DESCRIPTION
The ADC104S101 is
a low-power, four-channel

•
Specified Over a Range of Sample Rates
Four Input Channels
CMOS 10-bit analog-to-digital converter with a high-
speed serial interface. Unlike the conventional
practice of specifying performance at a single sample
rate only, the ADC104S101 is fully specified over a
sample rate range 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 four input
signals at inputs IN1 through IN4.
Variable Power Management
Single Power Supply with 2.7V - 5.25V Range

DNL: +0.26/−0.16 LSB (Typ)
INL: +0.4/−0.1 LSB (Typ)
SNR: 61.7 dB (Typ)
The output serial data is straight binary, and is
compatible with several standards, such as SPI™,
QSPI™, MICROWIRE, and many common DSP
serial interfaces.
Power Consumption:

–
3V Supply: 3.9 mW (Typ)
5V Supply: 11.4 mW (Typ)
The ADC104S101 operates with a single supply, that
can range from +2.7V to +5.25V. Normal power
consumption using a +3V or +5V supply is 3.9 mW
and 11.4 mW, respectively. The power-down feature
reduces the power consumption to just 0.12 µW using
a +3.6V supply, or 0.47 µW using a +5.5V supply.
