AD5601/AD5611/AD5621 Description 2.
7 V to 5.
5 V, <100 µA, 8-, 10-, 12-bit nanoDAC with SPI interface in tiny LFCSP and SC70 packages 05446-001 GENERAL DESCRIPTION The AD5602/AD5612/AD5622, members of the nanoDAC® family, are single 8-, 10-, 12-bit buffered voltage-out digital-toanalog converters (DAC) that operate from a single 2.
7 V to 5.
5 V supply, consuming <100 µA at 5 V.
These DACs come in tiny LFCSP and SC70 packages.
Each DAC contains an on-chip precision output amplifier that allows rail-to-rail output swing to be achieved.
The AD5602/AD5612/AD5622 use a 2-wire I2C compatible serial interface that operates in standard (100 kHz), fast (400 kHz), and high speed (3.
4 MHz) modes.
The references for AD5602/AD5612/AD5622 derive from the power supply inputs to give the widest dynamic output range.
Each device incorporates a power-on reset circuit that ensures the DAC output powers up to 0 V and remains there until a valid write takes place to the device.
