TI’s new data acquisition system with power, space and cost savings

Texas Instruments Incorporated today introduced the 100-kSPS ADS8201,
a complete 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
offers customers system-processing capability by integrating a complete
analog signal chain of four chips into one. This level of integration
provides greater design flexibility and reduces space, cost, power
consumption and design time in portable communications and medical
applications, as well as transducer interfaces, and GPS-based and
sensor data acquisition systems. For product details see: www.ti.com/ads8201-pr.

 Key features and benefits:

  • The ADS8201
    integrates a 12-bit, capacitor-based, successive approximate 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 flexibility.
  • High-impedance PGA and channel mapping allow for direct interface
    with a wide variety of sensors and for user-configurable gain per
  • A high-speed, wide-voltage serial interface simplifies serial port design.
  • Single-ended and differential-ended inputs allow a wide variety of interface options.
  • An eight-deep first in first out (FIFO) permits flexible data reading while reducing overhead on the microprocessor.
  • Maximize the ADS8201’s performance for portable communications, industrial and medical applications using TI’s low-noise, high-precision OPA376, OPA364 and OPA340, operational amplifiers, and the low-power REF3020 voltage reference.

 Availability and pricing

The ADS8201
is available now in a QFN-16 package. Pricing starts at $2.75 in
1,000-unit quantities. Customers can simplify the tasks of collecting
and analyzing ADC data and ease evaluation with the ADCPro modular software system.
