( DataSheet : www.DataSheet4U.com ) LTC1860L/LTC1861L µPower, 3V, 12-Bit, 150ksps 1- and 2-Channel ADCs in MSOP FEATURES s s s s DESCRIPTIO s s s s s s U APPLICATIO S 12-Bit 150ksps ADCs in MSOP Package Single 3V Supply Low Supply Current: 450µA (Typ) Auto Shutdown Reduces Supply Current to 10µA at 1ksps True Differential Inputs 1-Channel (LTC1860L) or 2-Channel (LTC1861L) Versions SPI/MICROWIRETM Compatible Serial I/O High Speed Upgrade to LTC1285/LTC1288 Pin Compatible with 16-Bit LTC1864L/LTC1865L No Minimum Data Transfer Rate The LTC®1860L/LTC1861L are 12-bit A/D converters that are offered in MSOP and SO-8 packages and operate on a single 3V supply. At 150ksps, the supply current is only 450µA. The supply current drops at lower speeds because the LTC1860L/LTC1861L automatically power down between conversions. These 12-bit switched capacitor successive approximation ADCs include sample-and-holds. The LTC1860L has a differential analog input with an external reference pin. The LTC1861L offers a softwareselectable 2-channel MUX and an external reference pin on the MSOP version. The 3-wire, serial I/O, MSOP or SO-8 package and extremely high sample rate-to-power ratio make these ADCs ideal choices for compact, low power, high speed systems. These ADCs can be used in ratiometric applications or with external references. The high impedance analog inputs and the ability to operate with reduced spans down to 1V full scale allow direct connection to signal sources in many.
