Overview
The AD5301BRMZ-REEL7 is a digital-to-analog converter (DAC) produced by Analog Devices Inc. This component is part of the AD5301/AD5311/AD5321 family, which offers 8-bit, 10-bit, and 12-bit resolutions, respectively. The AD5301BRMZ-REEL7 specifically is an 8-bit DAC. It operates on a single supply voltage ranging from 2.5 V to 5.5 V and features a 2-wire (I2C-compatible) serial interface. The device includes an on-chip output amplifier that provides rail-to-rail output swing and a slew rate of 0.7 V/μs. It also includes power-down modes and a power-on reset function, ensuring the DAC powers up in a defined state.
