LTC1599 16-Bit Byte Wide, Low Glitch Multiplying DAC with 4-Quadrant Resistors FEATURES DESCRIPTIO True 16-Bit Performance over Industrial The LTC 1599 is a 2-byte parallel input 16-bit multiplying Temperature Range current output DAC that operates from a single 5V supply. DNL and INL: 1LSB Max INL and DNL are accurate to 1LSB over the industrial On-Chip 4-Quadrant Resistors Allow Precise temperature range in both 2- and 4-quadrant multiplying 0V to 10V, 0V to 10V or 10V Outputs modes. True 16-bit 4-quadrant multiplication is achieved 2s Settling Time to 0.0015% (with LT 1468) with on-chip 4-quadrant multiplication resistors. Asynchronous Clear Pin Resets to Zero Scale The LTC1599 is available in 24-pin PDIP and SSOP packages or Midscale and is specified over the commercial and industrial tempera- Glitch Impulse: 1.5nV-s ture ranges. The device includes an internal deglitcher circuit 24-Lead SSOP Package that reduces the glitch impulse to 1.5nV-s (typ). The asyn- Low Power Consumption: 10W Typ chronous CLR pin resets the LTC1599 to zero scale when the Power-On Reset to Zero Scale or Midscale CLVL pin is at a logic low and to midscale when the CLVL pin 2-Byte Parallel Digital Interface is at a logic high. Available in 24-Lead SSOP and PDIP Packages For a full 16-bit wide parallel interface current output DAC, U refer to the LTC1597 data sheet. For serial interface 16-bit APPLICATIO S current output DACs, refer to the LTC1595/LTC1596 data Process Control and Industrial Automation sheet.
