FEATURE

The LTC

®1197/LTC1197L/LTC1199/LTC1199L are

10-bit A/D converters with sampling rates up to 500kHz.

They have 2.7V (L) and 5V versions and are offered in

8-pin MSOP and SO packages. Power dissipation is typi-

cally only 2.2mW at 2.7V (25mW at 5V) during full speed

operation. The automatic power down reduces supply

current linearly as sample rate is reduced. These 10-bit,

switched-capacitor, successive approximation ADCs in-

clude a sample-and-hold. The LTC1197/LTC1197L have a

differential analog input with an adjustable reference pin.

The LTC1199/LTC1199L offer a software-selectable

2-channel MUX.

The 3-wire serial I/O, MSOP and SO-8 packages, 2.7V

operation and extremely high sample rate-to-power ratio

make these ADCs ideal choices for compact, low power

high speed systems.

These circuits can be used in ratiometric applications or

with external references. The high impedance analog

inputs and the ability to operate with reduced spans below

1V full scale (LTC1197/LTC1197L) allow direct connec-

tion to signal sources in many applications, eliminating

the need for gain stages.
