MAX5105EEP+T

The MAX5105EEP+T from Analog Devices / Maxim Integrated is a nonvolatile, quad, 8-bit digital-to-analog converter (DAC). It operates from a single +2.7V to +5.5V supply, with an internal EEPROM storing DAC states even after power removal. Data from these nonvolatile registers automatically initialize DAC outputs and operating states during power-up.

This DAC features precision internal buffers that swing Rail-to-Rail, and its reference input range includes both ground and the positive rail. The MAX5105/MAX5106 series offers a software-controlled 10µA shutdown mode and a mute state. The MAX5105 includes an asynchronous MUTE input and a RDY/BSY output indicating nonvolatile memory status.

Key electrical specifications include an 8-bit resolution, a 2.7V to 5.5V operating voltage, and an SPI-compatible serial interface. It has an external reference type, voltage-buffered output, and a settling time of 6µs. The integral nonlinearity (INL) is ±2 (Max).

The device is available in a 20-QSOP package and operates within a wide temperature range of -40°C to +85°C. Mounting is via surface mount technology. Applications include digital gain and offset adjustments, programmable attenuators, portable instruments, and power-amp bias control.
