Hot-selling and scarce AD5301BRT 2-Wire Interface, Voltage Output 8-/10-/12-Bit DACs SOT23-6 spot stock

Product Descriptions

The AD5301/AD5311/AD5321 are single 8-, 10- and 12-bitbuffered voltage-output DACs that operate from a single +2.5 Vto +5.5 V supply consuming 120 µA at 3 V . The on-chip outputamplifier allows rail-to-rail output swing with a slew rate of0.7 V/µs . It uses a 2-wire (I² C compatible) serial interface thatoperates at clock rates up to 400 kHz . Multiple devices canshare the same bus .

The reference for the DAC is derived from the power supplyinputs and thus gives the widest dynamic output range . Theseparts incorporate a power-on-reset circuit, which ensures thatthe DAC output powers-up to zero volts and remains there untila valid write takes place.The parts contain a power-down featurewhich reduces the current consumption of the device to 50 nAat 3 V and provides software-selectable output loads while inpower-down mode .

The low power consumption in normal operation make theseDACs ideally suited to portable battery-operated equipment .The power consumption is 0.75 mW at 5 V, 0.36 mW at 3 Vreducing to 1 µW in all power-down modes .
