Description

The ADS8201 is a low-power, complete on-chip data acquisition system optimized for portable applications that require direct connections, wide dynamic range, and automatic operation with very low power consumption. The device includes a 12-bit, capacitor-based, successive approximation register (SAR) analog-to-digital converter (ADC); a high-performance, continuous-time programmable gain amplifier (PGA); and a fully automatic scan, 8-to-1 multiplexer (mux) with breakout to allow for system design flexibility.

Many other features are included to further optimize system operation. Conversion results may be saved in an onboard first-in/first-out (FIFO) buffer and read out at a later time. Each channel has a gain setting that can be loaded automatically when it is selected. To simplify the serial port design, the ADS8201 offers a high-speed, wide-voltage serial interface. The ADS8201 is ideal for sensor applications (for example, bridge sensors, pressure sensors, accelerometers, gyrosensors, temperature sensors, etc.) as used in gaming and navigation.

The ADS8201 is available in a 24-lead, 4×4 QFN package, and is specified over the –40°C to +85°C industrial temperature range.
