Quad 16-/12-Bit Rail-to-Rail

DACs with 10ppm/°C

Max Reference

FEATURES

DESCRIPTION

The LTC^®2654 is a family of quad 16-/12-bit rail-to-rail

DACswithintegrated10ppm/°Cmaximumreference. The

DACs have built-in high performance, rail-to-rail, output

buffers and are guaranteed monotonic. The LTC2654-L

has a full-scale output of 2.5V with the integrated refer-

ence and operates from a single 2.7V to 5.5V supply.

The LTC2654-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.

up to 50MHz. The LTC2654 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
