ADC101S051-Q1 (ACTIVE)

Automotive, Single Channel, 200 to 500 ksps, 10-Bit A/D Converter



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 WSON and SOT-23 packages. Operation is specified over the temperature range of −40°C to +85°C for the ADC101S051 and −40°C to +125°C for the ADC101S051Q.
