Texas Instruments (TI) has launched an on-chip data acquisition system (DAS) 100-kSPS ADS8201, which it claims to draw 600 uA of supply current at 2.2 V, resulting in up to 75% power savings over discrete implementations.
According to TI, the new DAS offers customers system-processing capability by integrating an analog signal chain of four chips into one. This level of integration is expected to reduce 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.
The ADS8201 integrates a 12-bit, capacitor-based, successive approximate register (SAR) analog-to-digital converter (ADC); a continuous-time programmable gain amplifier (PGA); and automatic scan, 8-to-1 multiplexer (mux) with breakout. High-impedance PGA and channel mapping allow for direct interface with a variety of sensors and for user-configurable gain per channel, TI said.
In addition, the new offering features single-ended and differential-ended inputs that allow a variety of interface options and an eight-deep first in first out (FIFO) for flexible data reading.
The ADS8201 is available in a QFN-16 package and pricing starts at $2.75 in 1,000-unit quantities.
