The MAX5222EKA+T is a dual, 8bit, voltage output serial DAC in 8 pin SOT-23 package. It contains two 8bit, buffered, voltage output digital to analogue converters (DAC A and DAC B). Both DAC outputs can source and sink 1mA to within 100mV of ground and VDD. 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 CS. The MAX5222's ultra low power consumption and tiny 8-pin SOT23 package make it ideal for portable and battery-powered applications. Supply current is less than 1mA and drops below 1μA in shutdown mode. In addition, the reference input is disconnected from the REF pin during shutdown, further reducing the system's total power consumption.
- Supply voltage range is 2.7V to 5.5V
- Operating temperature range from -40°C to 85°C
- Accuracy is ±0.3 LSB INL and DNL
- Operating current is 0.4mA
- Programmable shutdown mode
