Description

The AD5602 / AD5612 / AD5622, members of the nanoDAC family, are single 8-, 10-, 12-bit buffered voltage-out DACs 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.
