Description

General part information

LTC1861L Series

The LTC1860L/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 software-selectable 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 applications, eliminating the need for external gain stages.ApplicationsHigh Speed Data AcquisitionPortable or Compact InstrumentationLow Power Battery-Operated InstrumentationIsolated and/or Remote Data Acquisition
