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.
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 channel.
· 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.
