AD5305ARMZ Quad 8-Bit Voltage Output DAC Integrated Circuit Chip 10-Lead MSOP

The AD5305ARMZ is a quad, 8-bit, buffered voltage output digital-to-analog converter operating from a 2.5 V to 5.5 V supply. Four independent DACs share a two-wire I2C-compatible interface, and each output has a rail-to-rail amplifier spanning 0 V to the reference voltage.

The A grade is specified at plus or minus 1 LSB integral nonlinearity. Power consumption is low at 500 uA at 3 V and 600 uA at 5 V, which suits compact multi-channel trim in portable and industrial equipment.

The device is specified from -40 degrees C to +105 degrees C and supplied in a 10-lead MSOP. Its I2C-compatible serial interface allows several converters to share the same bus, making the AD5305ARMZ suitable for bias, offset and level setting across multiple nodes.

The AD5305 family covers several resolution, reference and package options. Because AD5305 devices are pin and software compatible within each package group, a design can move between AD5305 variants without rewriting firmware.
