LTC1591/LTC1597 14-Bit and 16-Bit Parallel Low Glitch Multiplying DACs with 4-Quadrant Resistors Fea T Descrip T n True 16-Bit Performance Over Industrial The LTC 1591/LTC1597 are pin compatible, parallel Temperature Range input 14-bit and 16-bit multiplying current output DACs n DNL and INL: 1LSB Max that operate from a single 5V supply. INL and DNL are n On-Chip 4-Quadrant Resistors Allow Precise 0V to accurate to 1LSB over the industrial temperature range 10V, 0V to 10V or 10V Outputs in both 2- and 4-quadrant multiplying modes. True 16- n Pin Compatible 14- and 16-Bit Parts bit 4-quadrant multiplication is achieved with on-chip n Asynchronous Clear Pin 4-quadrant multiplication resistors. n LTC1591/LTC1597: Reset to Zero Scale These DACs include an internal deglitcher circuit that n LTC1591-1/LTC1597-1: Reset to Mid-Scale reduces the glitch impulse to less than 2nV-s (typ). The n Glitch Impulse < 2nV-s asynchronous CLR pin resets the LTC1591/LTC1597 to n Low Power Consumption: 10W Typ zero scale and LTC1591-1/LTC1597-1 to mid-scale. n Power-On Reset The LTC1591/LTC1597 are available in the 28-pin SSOP n 28-Lead SSOP Package package and are specified over the industrial temperature range. a T For serial interface 16-bit current output DACs refer to the n Process Control and Industrial Automation LTC1595/LTC1596 data sheet. n Direct Digital Waveform Generation n L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear Software-Controlled Gain Adjustment Technology Corporation.
