Description

General part information

MAX5548 Series

The MAX5548 dual, 8-bit, digital-to-analog converter (DAC) features high-output-current capability. The MAX5548 sources up to 30mA per DAC making it ideal for PIN diode biasing applications. Outputs can also be paralleled for high-current applications (up to 60mA typ). Operating from a single +2.7V to +5.25V supply, the MAX5548 typically consumes 1.5mA per DAC in normal operation and less than 1µA (max) in shutdown mode. The MAX5548 also features low output leakage current in shutdown mode (±1µA max) that is essential to ensure that the external PIN diodes are off.Additional features include an integrated +1.25V bandgap reference, and a control amplifier to ensure high accuracy and low-noise performance. A separate reference input (REFIN) allows for the use of an external reference source, such as the MAX6126, for improved gain accuracy. A pin-selectable I²C-/SPI™-compatible serial interface provides optimum flexibility for the MAX5548. The programmable output current's maximum value is set using software and an adjustment resistor. The MAX5548 is available in a 3mm × 3mm, 16-pin, thin QFN package, and is specified over the extended (-40°C to +85°C) temperature range.ApplicationsPIN Diode BiasingRF Attenuator ControlVCO Tuning
