Typical Application
Description
The LTC1864L/LTC1865L are 16-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 LTC1864L/LTC1865L automatically power down between conversions. These 16-bit switched capacitor successive approximation ADCs include sample-and-holds. The LTC1864L has a differential analog input with an external reference pin. The LTC1865L offers a software selectable 2-channel MUX and an external reference pin on the MSOP version.
The 3-wire, serial I/O, small MSOP or SO-8 package and extremely high sample rate-to-power ratio make theseADCs ideal choices for compact, low power, high speed systems.
These ADCs can be used in ratiometric applications or with external references. The high impedance analoginputs 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.
