The multichannel AS8510 IC (integrated circuit) from austriamicrosystems features zero offset for simultaneous voltage, current, and temperature measurement in conventional, hybrid, or electric vehicles. According to the company, the high-precision data-acquisition front-end IC provides designers with the highest accuracy available and the flexibility required for a variety of applications. In addition, by adding an austriamicrosystems' LIN (Local Interconnect Network) companion IC and a cost-effective microcontroller, automotive applications can realize reduced time to market in an evolving field at a competitive price and improved performance. The flexible sensor interface IC offers advantages over alternative solutions, including, claims the company, being the first to feature a 16-bit dual-channel ADC (analog-to-digital converter) + PGA (programmable gain amplifier) architecture with less than one lower sideband of offset and noise. Each channel has a low-drift programmable gain amplifier for handling ±160 mV signals or 0 to 1 V when bypassing PGA.
