2.5 V to 5.5 V, 500 A, 2-Wire Interface Quad Voltage Output, 8-/10-/12-Bit DACs AD5305/AD5315/AD5325 FEATURES GENERAL DESCRIPTION AD5305: 4 buffered 8-bit DACs in 10-lead MSOP The AD5305/AD5315/AD53251 are quad 8-, 10-, and 12-bit A version: ±1 LSB INL, B version: ±0.625 LSB INL buffered voltage output DACs in a 10-lead MSOP that operate AD5315: 4 buffered 10-bit DACs in 10-lead MSOP from a single 2.5 V to 5.5 V supply, consuming 500 A at 3 V. A version: ±4 LSB INL, B version: ±2.5 LSB INL Their on-chip output amplifiers allow rail-to-rail output swing AD5325: 4 buffered 12-bit DACs in 10-lead MSOP with a slew rate of 0.7 V/s. A 2-wire serial interface that A version: ±16 LSB INL, B version: ±10 LSB INL operates at clock rates up to 400 kHz is used. This interface is Low power operation: 500 A @ 3 V, 600 A @ 5 V SMBus compatible at VDD < 3.6 V. Multiple devices can be 2-wire (I2C®-compatible) serial interface placed on the same bus. 2.5 V to 5.5 V power supply Guaranteed monotonic by design over all codes The references for the four DACs are derived from one Power-down to 80 nA @ 3 V, 200 nA @ 5 V reference pin. The outputs of all DACs can be updated Three power-down modes simultaneously using the software LDAC function. Double-buffered input logic The parts incorporate a power-on reset circuit, which ensures Output range: 0 V to VREF that the DAC outputs power up to 0 V and remain there until a Power-on reset to 0 V valid write takes place to the device. There is also a software Simultaneous update of outputs (LDAC function) clear function to reset all input and DAC registers to 0 V. The Software clear facility parts contain a power-down feature that reduces the current Data readback facility consumption of the devices to 200 nA @ 5 V (80 nA @ 3 V). On-chip rail-to-rail output buffer amplifiers Temperature range: -40°C to +105°C The low power consumption of these parts in normal operation makes them ideally suited for portable battery-operated equip- APPLICATIONS ment. The power consumption is 3 mW at 5 V, 1.5 mW at 3 V, reducing to 1 W in power-down mode.
