16-Bit Byte Wide, Low Glitch Multiplying DAC with 4-Quadrant Resistors

The LTC1599 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.

The LTC1599 is available in 24-pin PDIP and SSOP packages and is specified over the commercial and industrial temperature ranges. The device includes an internal deglitcher circuit that reduces the glitch impulse to 1.5nV-s (typ). The asynchronous CLR pin resets the LTC1599 to zero scale when the CLVL pin is at a logic low and to midscale when the CLVL pin is at a logic high.

For a full 16-bit wide parallel interface current output DAC, refer to the LTC1597 data sheet. For serial interface 16-bit current output DACs, refer to the LTC1595/LTC1596 data sheet.
