LTC2654
Quad 16-/12-Bit Rail-to-Rail
DACs with 10ppm/°C
Max Reference
DESCRIPTION
The LTC
®
2654 is a family of quad 16-/12-bit rail-to-rail
DACs with integrated 10ppm/°C maximum reference . 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.
These DACs communicate via a SPI/MICROWIRE™ com-
patible 4-wire serial interface which operates at clock rates
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
tied to V
CC
, the DACs reset to mid-scale.
