Linear Technology Corp. has introduced a family of pin- and software-compatible 16- and 12bit SAR ADCs with a guaranteed operation across the -40?C to 125?C automotive temperature range.

Operating from a single 5V supply, the 16bit LTC1864/LTC1865 and 12bit LTC1860/LTC1861 each draw 850?A and are guaranteed for output rates up to 250KSps. All four ADCs communicate via a 3-wire SPI-compatible serial interface.

With their tiny size, low power and guaranteed temperature range, the ADCs are suitable for high-resolution automotive applications such as temperature sensing, airflow sensing or engine fluid measurement. The LTC1860, LTC1861, LTC1864 and LTC1865 claim to offer the highest resolution and smallest solution size family of automotive-grade SAR ADCs.

The LTC1864 and LTC1860 measure a single differential channel in a tiny MSOP-8 package while the LTC1865 and LTC1861 measure two single-ended channels in an MSOP-10 package.

The LTC1860, LTC1861, LTC1864, and LTC1865 automotive grade ADCs are all available. Pricing starts at $2.91 for 1,000-piece quantities.
