Part Description: AD5337/AD5338/AD5339 2.5 V to 5.5 V 250 µA 2-Wire Interface Dual Voltage Output 8-/10-/12-Bit DACs Data Sheet (Rev. C)

Part Details:

2.5 V to 5.5 V, 250 A, 2-Wire Interface, Dual Voltage Output, 8-/10-/12-Bit DACs AD5337/AD5338/AD5339 FEATURES GENERAL DESCRIPTION AD5337 The AD5337/AD5338/AD5339 are dual 8-, 10-, and 12-bit 2 buffered 8-bit DACs in 8-lead MSOP buffered voltage output DACs, respectively. Each part is housed AD5338, AD5338-1 in an 8-lead MSOP package and operates from a single 2.5 V to 2 buffered 10-bit DACs in 8-lead MSOP 5.5 V supply, consuming 250 A at 3 V. On-chip output amplifiers AD5339 allow rail-to-rail output swing with a slew rate of 0.7 V/s. A 2- 2 buffered 12-bit DACs in 8-lead MSOP wire serial interface operates at clock rates up to 400 kHz. This Low power operation: 250 A @ 3 V, 300 A @ 5 V interface is SMBus compatible at VDD < 3.6 V. Multiple devices 2-wire (I2C-compatible) serial interface can be placed on the same bus. 2.5 V to 5.5 V power supply The references for the two DACs are derived from one reference Guaranteed monotonic by design over all codes pin. The outputs of all DACs can be updated simultaneously Power-down to 80 nA @ 3 V, 200 nA @ 5 V using the software LDAC function. The parts incorporate a 3 power-down modes power-on reset circuit to ensure that the DAC outputs power up Double-buffered input logic to 0 V and remain there until a valid write to the device takes Output range: 0 V to VREF place. A software clear function resets all input and DAC Power-on reset to 0 V registers to 0 V. A power-down feature reduces the current Simultaneous update of outputs (LDAC function) consumption of the devices to 200 nA @ 5 V (80 nA @ 3 V). Software clear facility Data readback facility The low power consumption of these parts in normal operation On-chip rail-to-rail output buffer amplifiers makes them ideally suited to portable battery-operated equip- Temperature range: -40°C to +105°C ment. The power consumption is typically 1.5 mW at 5 V and 0.75 mW at 3 V, reducing to 1 W in power-down mode.
