LTC1860/LTC1861

µPower, 12-Bit, 250ksps

1- and 2-Channel ADCs in MSOP

FEATURES

DESCRIPTIO

TheLTC^®1860/LTC1861are12-bitA/Dconvertersthatare

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-bitswitchedcapacitorsuccessiveapproximationADCs

include sample-and-holds.TheLTC1860hasadifferential

analoginputwithanadjustablereferencepin.TheLTC1861

offers a software-selectable 2-channel MUX and an ad-

justable reference pin on the MSOP version.

Pin Compatible with 16-Bit LTC1864/LTC1865

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.

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.
