100-kSPS, low power on-chip data acquisition system from TI

TI has introduced the ADS8201, a new 100-kSPS, low power on-chip data acquisition system (DAS) that draws only 600 uA of supply current at 2.2 V, resulting in up to 75 percent power savings over discrete implementations. The ADS8201 is suitable for portable communications and medical applications, transducer interfaces, GPS chipsets and sensor data acquisition systems.

The ADS8201 DAS integrates a 12-bit, capacitor-based, successive approximate register (SAR) analog-to-digital converter (ADC), a high-performance continuous-time programmable gain amplifier (PGA), a fully automatic scan, and 8-to-1 multiplexer (mux) with breakout to allow for system flexibility.

The key features of the ADS8201 DAS are,

SPI-/ DSP-Compatible Serial Interface
Separate I/O Supply (2.2V to 5.5V)
Onboard 8×1 FIFO Buffer
High-impedance PGA and channel mapping allow for direct interface with a wide variety of sensors and for user-configurable gain per channel
A high-speed, wide-voltage serial interface simplifies serial port design
Single-ended and differential-ended inputs allow a variety of interface options
An eight-deep first in first out (FIFO) permits flexible data reading while reducing overhead on the microprocessor
Built-in hardware features On-chip Conversion Clock (CCLK), hardware/software reset,
and programmable status/polarity for BUSY/INT

Package: QFN-16 package
Price: Starts at $2.75 for 1k pieces
