+2.7V to +5.5V, Low-Power, Quad, Parallel

8-Bit DAC with Rail-to-Rail Voltage Outputs

General DescriptionFeatures

The MAX5100 parallel-input, voltage-output, quad 8-bit

digital-to-analog converter (DAC) operates from a sin-

, and the reference input range

includes both ground and the positive rail. All four

DACs share a common reference input.

oUltra-Small 20-Pin TSSOP Package

The MAX5100 provides double-buffered logic inputs:

four 8-bit buffer registers followed by four 8-bit DAC

registers. This keeps the DAC outputs from changing

DAC registers.

oPower-On Reset Sets All Registers to Zero

The MAX5100 features a 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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional

operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to

absolute maximum rating conditions for extended periods may affect device reliability.
