LTC2657
Octal I2C 16-/12-Bit
Rail-to-Rail DACs with
10ppm/В°C Max Reference
DESCRIPTION FEATURES The LTCВ®2657 is a family of octal I2C 16-/12-Bit Rail-toRail DACs with Integrated 10ppm/В°C Max Reference. The
DACs have built-in high performance, rail-to-rail, output
buffers and are guaranteed monotonic. The LTC2657-L has
a full-scale output of 2.5V with the integrated reference and
operates from a single 2.7V to 5.5V supply. The LTC2657-H
has a full-scale output of 4.096V with the integrated reference
and operates from a 4.5V to 5.5V supply. Each DAC can also
operate with an external reference, which sets the full-scale
output to 2 times the external reference voltage. Integrated Reference 10ppm/В°C Max
