Linear Technology LTC1199CMS8

Description
The LTC1197/LTC1197L/LTC1199/LTC1199L are 10-bit analog-to-digital converters (ADCs) with sampling rates up to 500kHz. They are available in 2.7V (L) and 5V versions and are offered in 8-pin MSOP and SO packages. These ADCs feature low power dissipation, typically 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.
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.
