Description

LTC2655: Quad I

2

C  

16-/12-Bit Rail-to-Rail DACs with 

10ppm/°C Max Reference

Demonstration circuit 1703A features the LTC

®

2655 quad 

16-/12-bit DAC. The LTC2655 is a family of 16-/12- bit 

rail-to-rail DACs with integrated 10ppm/°C maximum 

reference. The LTC2655 advances performance standards 

for output drive, crosstalk and load regulation in single 

supply, voltage-output multiple DACs.
