TI's new data acquisition system delivers up to 75 percent power, space and cost savings

Highly flexible system simplifies compact, power-sensitive and multi-sensor-based portable designs

(PresseBox) (Dallas, ) Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced the 100kSPS ADS8201, a complete onchip 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 systemprocessing 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 GPSbased and sensor data acquisition systems. For product details see:

Key features and benefits:

- The ADS8201 integrates a 12bit, capacitorbased, successive approximate register (SAR) analogtodigital converter (ADC); a highperformance continuoustime programmable gain amplifier (PGA); and a fully automatic scan, 8to-1 multiplexer (mux) with breakout to allow for system flexibility.
- Highimpedance PGA and channel mapping allow for direct interface with a wide variety of sensors and for userconfigurable gain per channel.
- A highspeed, widevoltage serial interface simplifies serial port design.
- Singleended and differentialended inputs allow a wide variety of interface options.
- An eightdeep 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 lownoise, highprecision OPA376, OPA364 and OPA340, operational amplifiers, and the lowpower REF3020 voltage reference.

Availability and pricing

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