LTC1595/LTC1596/LTC1596-1 Serial 16-Bit Multiplying DACs FEATURES DESCRIPTION n SO-8 Package (LTC1595) The LTC 1595/LTC1596/LTC1596-1 are serial input, 16-bit n DNL and INL: 1LSB Max multiplying current output DACs. The LTC1595 is pin and n Low Glitch Impulse: 1nV-s Typ hardware compatible with the 12-bit DAC8043 and comes n Fast Settling to 1LSB: 2s (with LT1468) in 8-pin PDIP and SO packages. The LTC1596 is pin and n Pin Compatible with Industry Standard hardware compatible with the 12-bit DAC8143/AD7543 12-Bit DACs: DAC8043 and DAC8143/AD7543 and comes in the 16-pin SO wide package. n 4-Quadrant Multiplication Both are specified over the industrial temperature range. n Low Supply Current: 10A Max Sensitivity of INL to op amp V is reduced by five times OS n Power-On Reset compared to the industry standard 12-bit DACs, so most n LTC1595/LTC1596: Resets to Zero-Scale systems can be easily upgraded to true 16-bit resolution n LTC1596-1: Resets to Mid-Scale and linearity without requiring more precise op amps. n 3-Wire SPI and MICROWIRE Compatible These DACs include an internal deglitching circuit that Serial Interface n reduces the glitch impulse by more than ten times to less Daisy-Chain Serial Output (LTC1596) n than 1nV-s typ. Asynchronous Clear Input n LTC1596: Clears to Zero-Scale The DACs have a clear input and a power-on reset. The n LTC1596-1: Clears to Mid-Scale LTC1595 and LTC1596 reset to zero-scale. The LTC1596-1 is a version of the LTC1596 that resets to mid-scale. APPLICATIONS L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear Technology Corporation.
