Pin- & Software-Compatible 16-/12-Bit ADCs in MSOP Packages Guaranteed to +125°C

Milpitas,CA, (PresseBox) - Linear Technology Corporation introduces a family of pin- and software-compatible 16- and 12-bit SAR ADCs (Analog-to-Digital Converters) that guarantee operation across the -40°C to +125°C automotive temperature range. Operating from a single 5V supply, the 16-bit LTC1864/LTC1865 and 12-bit LTC1860/LTC1861 each draw only 850uA and are guaranteed for output rates up to 250ksps. The LTC1864 and LTC1860 are pin- and software-compatible ADCs that measure a single differential channel in a tiny MSOP-8 package. The LTC1865 and LTC1861 are pin- and software-compatible ADCs that measure two single-ended channels in an MSOP-10 package.

All four ADCs communicate via a 3-wire SPI-compatible serial interface. Their tiny size, low power, and guaranteed -40°C to +125°C temperature range make these ADCs a great fit for high-resolution automotive applications such as temperature sensing, airflow sensing, or engine fluid measurement. The LTC1860, LTC1861, LTC1864, and LTC1865 are the highest resolution, smallest solution size family of automotivegrade SAR ADCs available on the market today.

The LTC1860, LTC1861, LTC1864, and LTC1865 automotive grade ADCs are all available today.
