Maxim MAX522CPA

Voltage - BufferedSPI2.7V ~ 5.5V0°C ~ 70°C

Overview

The MAX522CPA contains two 8-bit, buffered, voltage-output digital-to-analog converters (DAC A and DAC B) in small 8-pin SO and DIP packages. DAC A's buffer can source and sink 5mA, and DAC B's output can source and sink 500μA, both to within 0.5V of ground and VDD. The MAX522CPA operates with a single +2.7V to +5.5V supply. The device utilizes a 3-wire serial interface, which operates at clock rates up to 5MHz and is compatible with SPI, QSPI, and Microwire interface standards. The serial input shift register is 16 bits long and consists of eight bits of DAC input data and eight 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 MAX522's ultra-low power consumption and small 8-pin SO 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. The software format is compatible with the MAX512/MAX513 triple 8-bit DACs.
