DESCRIPTION
The LTC®1603 is a 250ksps, 16-bit sampling A/D converter that draws only 220mW from ±5V supplies. This high performance device includes a high dynamic range sample-and-hold, a precision reference and a high speed parallel output. Two digitally selectable power shutdown modes provide power savings for low power systems.
