The LTC
®
1864L/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 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.
