DS4426规格书详情

General Description

The DS4426 contains four I2C-adjustable current DACs capable of sinking or sourcing current. External resistors set the full-scale range of each output. Each DAC output has 127 sink and 127 source steps that are programmed by the I2C interface. Power-supply tracking functionality is provided for three channels using dedicated control inputs. Once power-supply tracking is

accomplished, the current outputs default to zero. Two address pins allow up to four DS4426 devices to exist on the same I2C bus.

Features

♦ Four Current DACs

  50µA to 200µA Adjustable Full-Scale Range

  127 Settings Each for Sink and Source

♦ Power-Supply Tracking

   Power-Supply Sequencing

   Ramp-Up and Ramp-Down Tracking Control

   Ratiometric Tracking Support

♦ +2.7V to +5.5V Operation

♦ I2C-Compatible Serial Interface

♦ Two Address Input Pins Allow Up to Four Devices on Same I2C Bus

♦ Lead-Free, 28-Pin TQFN Package (4mm x 4mm) with Exposed Pad

♦ Industrial Temperature Range: -40°C to +85°C
