Linear has transceiver that is reliable in the field

Description The LTC®2862/LTC2863/LTC2864/LTC2865 are low power, 20Mbps or 250kbps RS485/RS422 transceivers operating on 3V to 5.5V supplies that feature ±60V overvoltage fault protection on the data transmission lines during all modes of operation, including power-down. Low EMI slew rate limited data transmission is available in a logic-selectable 250kbps mode in the LTC2865 and in 250kbps versions of the L ...

Arduino and the LTC2440 24bit ADC

Have you ever wondered how to improve the resolution of analog readings of your Arduino board? If yes, this is for you. John Beale, discussing on the Dangerous Prototypes’ forum, quickly describes how to connect a Linear’s LTC2440 ADC to an Arduino board, which will provide you with an amazing 24 bit resolution. The ADC, which is available in a SSOP package, can be connected to the Arduino via the SPI bus. ...
