Part Details:

2.5 V to 5.5 V, 120 A, 2-Wire Interface, Voltage-Output 8-/10-/12-Bit DACs AD5301/AD5311/AD5321 FEATURES GENERAL DESCRIPTION AD5301: buffered voltage output 8-bit DAC The AD5301/AD5311/AD53211 are single 8-/10-/12-bit, buff- AD5311: buffered voltage output 10-bit DAC ered, voltage-output DACs that operate from a single 2.5 V to AD5321: buffered voltage output 12-bit DAC 5.5 V supply, consuming 120 A at 3 V. The on-chip output 6-lead SOT-23 and 8-lead MSOP packages amplifier allows rail-to-rail output swing with a slew rate of Micropower operation: 120 A @ 3 V 0.7 V/s. It uses a 2-wire (I2C-compatible) serial interface that 2-wire (I2C®-compatible) serial interface operates at clock rates up to 400 kHz. Multiple devices can share Data readback capability the same bus. 2.5 V to 5.5 V power supply The reference for the DAC is derived from the power supply Guaranteed monotonic by design over all codes inputs and thus gives the widest dynamic output range. These Power-down to 50 nA @ 3 V parts incorporate a power-on reset circuit, which ensures that Reference derived from power supply the DAC output powers up to 0 V and remains there until a Power-on reset to 0 V valid write takes place. The parts contain a power-down feature On-chip rail-to-rail output buffer amplifier that reduces the current consumption of the device to 50 nA at 3 power-down functions 3 V and provides software-selectable output loads while in APPLICATIONS power-down mode. Portable battery-powered instruments The low power consumption in normal operation makes these Digital gain and offset adjustment DACs ideally suited to portable battery-operated equipment. The Programmable voltage and current sources power consumption is 0.75 mW at 5 V and 0.36 mW at 3 V, Programmable attenuators reducing to 1 W in all power-down modes. 1 Protected by U.S. Patent No. 5684481, other patents pending.
