Description : 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 performance 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.

Features
■ Specified over a range of sample rates.
■ 6-lead LLP and SOT-23 packages
■ Variable POWER management
■ Single POWER supply with 2.7V - 5.25V range
■ SPI™/QSPI™/MICROWIRE/DSP compatible

Applications
■ Portable Systems
■ Remote Data Acquisition
■ Instrumentation and Control Systems
