Product Details
The MAX5223 contains two 8-bit, buffered, voltage output digital-to-analog converters (DAC A and DAC B) in a small 8-pin SOT23 package. DAC outputs can source and sink 1mA to within 100mV of ground and VDD. The MAX5223 operates with a single +2.7V to +5.5V supply.
The device uses a 3-wire serial interface, which operates at clock rates up to 25MHz and is compatible with SPI™, QSPI™, and MICROWIRE™ interface standards. The serial input shift register is 16 bits long and consists of 8 bits of DAC input data and 8 bits for DAC selection and shutdown control. DAC registers can be loaded independently or in parallel at the positive edge of active-low CS.
The MAX5223's ultra-low power consumption and tiny 8-pin SOT23 package make it ideal for portable and battery-powered applications. Supply current is a low 100µA and drops below 1µA in shutdown mode. In addition, the reference input is disconnected from the REF pin during shutdown, which reduces the system's total power consumption.
