- Pin Compatible 14- and 16-Bit Parts
- Asynchronous Clear Pin
- LTC1591/LTC1597: Reset to Zero Scale
- LTC1591-1/LTC1597-1: Reset to Midscale

- Low Power Consumption: 10µW Typ
- Power-On Reset
The LTC1591/LTC1597 are pin compatible, parallel input 14-bit and 16-bit multiplying current output DACs that operate 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.
These DACs include an internal deglitcher circuit that reduces the glitch impulse to less than 2nV-s (typ). The asynchronous CLR pin resets the LTC1591/LTC1597 to zero scale and LTC1591-1/LTC1597-1 to mid-scale.
The LTC1591/LTC1597 are available in 28-pin SSOP and PDIP packages and are specified over the industrial temperature range.
For serial interface 16-bit current output DACs refer to the LTC1595/LTC1596 data sheet.
