Quad 12-/10-/8-Bit I C V

DACs with 10ppm/°C Reference

Features

Description

The LTC^®2635 is a family of quad 12-, 10-, and 8-bit

voltage-output DACs with an integrated, high-accuracy,

low-drift reference in a 16-pin QFN or a 10-lead MSOP

package. It has rail-to-rail output buffers and is guaran-

teed monotonic. The LTC2635-L has a full-scale output

of 2.5V, and operates from a single 2.7V to 5.5V supply.

The LTC2635-H has a full-scale output of 4.096V, 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 the external reference voltage.

Maximum INL Error: 2.5 LSꢀ (LTC2635-12)

Power-On-Reset to Zero-Scale/Mid-Scale/Hi-Z

Low Noise: 0.75mV 0.1Hz to 200kHz

2.7V to 5.5V Supply Range (LTC2635-L)

Ultralow Crosstalk ꢀetween DACs (3nV•s)

These DACs communicate via a 2-wire I C-compatible

serialinterface.TheLTC2635operatesinboththestandard

mode (clock rate of 100kHz) and the fast mode (clock rate

of 400kHz). The LTC2635 incorporates a power-on reset

circuit. Options are available for reset to zero-scale, reset

tomid-scaleininternalreferencemode,resettomid-scale

in external reference mode, or reset with all DAC outputs

in a high-impedance state after power-up.
