DACs with10ppm/°C Reference  
FEATURES  
DESCRIPTION  
®
The LTC 2636 is a family of octal 12-, 10-, and 8-bit  
n
Integrated Precision Reference  
2.5V Full-Scale 10ppm/°C (LTC2636-L)  
4.096V Full-Scale 10ppm/°C (LTC2636-H)  
voltage-output DACs with an integrated, high-accuracy,  
low-drift 10ppm/°C reference in 14-lead DFN and 16-lead  
MSOP packages. It has a rail-to-rail output buffer and is  
guaranteed monotonic. The LTC2636-L has a full-scale  
output of 2.5V, and operates from a single 2.7V to 5.5V  
supply. The LTC2636-H has a full-scale output of 4.096V,  
and operates from a 4.5V to 5.5V supply. Each DAC can  
also operate with an external reference, which sets the  
DAC full-scale output to the external reference voltage.  
n
Maximum INL Error: 2.5LSB (LTC2636-12)  
n
Low Noise: 0.75mV 0.1Hz to 200KHz  
P-P  
n
Guaranteed Monotonic Over –40°C to 125°C  
Temperature Range  
n
Selectable Internal or External Reference  
n
2.7V to 5.5V Supply Range (LTC2636-L)  
n
Ultralow Crosstalk Between DACs (<2.4nV•s)  
n
Low Power: 0.9mA at 3V (LTC2636-L)  
These DACs communicate via an SPI/MICROWIRE-com-  
patible 3-wire serial interface which operates at clock  
rates up to 50MHz. Hardware clear (CLR) and asynchro-  
n
Power-On-Reset to Zero-Scale/Mid-Scale  
n
Double-Buffered Data Latches  
n
Tiny 14-Lead 4mm × 3mm DFN and 16-Lead MSOP  
Packages  
nous DAC update (LDAC) pins are available in the MSOP  
package. The LTC2636 incorporates a power-on reset  
circuit. Options are available for reset to zero-scale or  
reset to mid-scale in internal reference mode, or reset  
to mid-scale in external reference mode after power-up.
