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