nn High Speed Upgrade to LTC1286/LTC1298
nn Pin Compatible with 16-Bit LTC1864/LTC1865
nn Guaranteed Operation to 125°C (MSOP Package) The LTC®1860/LTC1861 are 12-bit A/D converters that are
offered in MSOP and SO-8 packages and operate on a single
5V supply. At 250ksps, the supply current is only 850µA.
The supply current drops at lower speeds because the
LTC1860/LTC1861 automatically power down to a typical
supply current of 1nA between conversions. These 12-bit
switched capacitor successive approximation ADCs include
sample-and-holds. The LTC1860 has a differential analog
input with an adjustable reference pin. The LTC1861 offers …
