LTC1860L/LTC1861L

µPower, 3V, 12-Bit, 150ksps

1- and 2-Channel ADCs in MSOP

FEATURES

DESCRIPTIO

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 be-

tween conversions. These 12-bit switched capacitor suc-

cessive approximation ADCs include sample-and-holds.

The LTC1860L has a differential analog input with an

external reference pin. The LTC1861L offers a software-

selectable2-channelMUXandanexternalreferencepinon

the MSOP version.

No Minimum Data Transfer Rate

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.
