AD5305BRMZ

AD5305BRMZ Description

The AD5305BRMZ from Analog Devices Inc. is a quad-channel, 8-bit digital-to-analog converter (DAC) designed for precision voltage output applications. Housed in a compact 10-MSOP package, it features an I2C-compatible serial interface, making it ideal for space-constrained designs requiring multiple DAC channels. The device operates with dual supply voltages (2.5V to 5.5V for both analog and digital domains), ensuring compatibility with a wide range of systems. With a settling time of just 8µs and low INL/DNL (±0.15 LSB, ±0.02 LSB), the AD5305BRMZ delivers high accuracy and fast response for dynamic control applications. Its external reference architecture allows flexibility in setting the output range, while the string DAC design ensures monotonicity and reliability.
