ADC101S051
Single Channel, 200 to 500 ksps, 10-Bit A/D Converter
General Description
The ADC101S051 is a low-power, single channel CMOS
10-bit analog-to-digital converter with a high-speed serial
interface. Unlike the conventional practice of specifying per-
formance at a single sample rate only, the ADC101S051 is
fully specified over a sample rate range of 200 ksps to 500
ksps. The converter is based upon a successive-
approximation register architecture with an internal track-
and-hold circuit.
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 ADC101S051 operates with a single supply that can
range from +2.7V to +5.25V. Normal power consumption
using a +3.6V or +5.25V supply is 2.7 mW and 9.7 mW,
respectively. The power-down feature reduces the power
consumption to as low as 2.6 µW using a +5.25V supply.
The ADC101S051 is packaged in 6-lead LLP and SOT-23
packages. Operation over the industrial temperature range
of −40˚C to +85˚C is guaranteed.
