Maxim Integrated Products introduces the DS4422/DS4424 low-cost, dual-/quad-channel, sink/source current DACs. These I²C-controlled, 7-bit current DACs feature two (DS4422)/four (DS4424) output channels that are specifically designed for power-supply margining and adjustment. Each output channel provides control of a DC-DC power supply by sinking or sourcing current directly into the power supply's feedback node. This control technique allows existing power-supply designs to be margined and adjusted with minimal redesign, thus making the DS4422/DS4424 ideal for servers, video processing cards, and other DC-DC power-supply applications.

MILPITAS, CA – April 29, 2008 – Linear Technology Corporation introduces the LTC2755-16, a quad 16-bit current output digital-to-analog converter (DAC) with six software-programmable output ranges. The LTC2755-16 guarantees 16-bit linearity (±1LSB (max) INL and DNL) over the industrial temperature range without any adjustment. Each DAC output can be individually programmed through a parallel interface or can be pin-strapped for operation within a single range. A current output DAC allows end-users to customize their output amplifiers for optimal performance, depending on the requirements for better DC or AC specifications, lower noise, or higher speed.
