DACs with 10ppm/°C

Max Reference

FEATURES

DESCRIPTION

The LTC^®2656 is a family of octal 16-/12-bit rail-to-rail

DACs with a precision integrated reference. The DACs have

built-in high performance, rail-to-rail, output buffers and

are guaranteed monotonic.The LTC2656-L has a full-scale

output of 2.5V with the integrated 10ppm/°C reference and

operates from a single 2.7V to 5.5V supply. The LTC2656-H

has a full-scale output of 4.096V with the integrated refer-

enceandoperatesfroma4.5Vto5.5Vsupply.EachDACcan

also operate with an external reference, which sets the DAC

up to 50MHz. The LTC2656 incorporates a power-on reset

circuit that is controlled by the PORSEL pin. If PORSEL

is tied to GND the DACs reset to zero-scale. If PORSEL is
