A/D converters guaranteed to +125 degrees C

Milpitas, Calif.—Linear Technology Corp. has launched a family of pin- and software-compatible 16- and 12-bit SAR A/D 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 850-µA and are guaranteed for output rates up to 250-ksps. The LTC1864 and LTC1860 are pin- and software-compatible A/D converters that measure a single differential channel in a tiny MSOP-8 package. The LTC1865 and LTC1861 are pin- and software-compatible A/D converters that measure two single-ended channels in an MSOP-10 package.

All four A/D converters 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 A/D converters well-suited for high-resolution automotive applications such as temperature sensing, airflow sensing, or engine fluid measurement.

Pricing: Begins at $2.91 for 1,000-piece quantities.
Availability: Now.
Datasheet: LTC1860 and LTC1864.
