FEATURES
DESCRIPTIO
■
True 16-Bit Performance over Industrial
The LTC®1599 is a 2-byte parallel input 16-bit multiplying
current output DAC that operates from a single 5V supply.
INL and DNL are accurate to 1LSB over the industrial
temperature range in both 2- and 4-quadrant multiplying
modes. True 16-bit 4-quadrant multiplication is achieved
with on-chip 4-quadrant multiplication resistors.
