MAX5100BEUP+T

The MAX5100BEUP+T is a low power, quad, parallel 8bit digital to analogue converter (DAC) with rail to rail voltage outputs in 20 pin TSSOP package. This parallel input, voltage output DAC operates from single 2.7V to 5.5V supply and comes in a space saving package. Internal precision buffers swing rail to rail and reference input range includes both ground and positive rail. All four DACs share a common reference input. It provides double buffered logic inputs, four 8bit buffer registers followed by four 8bit DAC registers. This keeps the DAC outputs from changing during write operation. An asynchronous control pin (active-low LDAC) allows for simultaneous updating of DAC registers. The MAX5100 has shutdown mode that reduces current to 1nA as well as a power-on reset mode that resets all registers to code 00 hex on power-up. It is used in digital gain and offset adjustments, programmable attenuators and power-amp bias control.
