Description

The LTC^(R) 1604 is a 333ksps, 16-bit sampling A/D con- verter 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.

The LTC1604's full-scale input range is ±2.5V. Outstand- ing AC performance includes 90dB S/(N+D) and 100dB THD at a sample rate of 333ksps.
