2.5 V to 5.5 V, 500 A, Quad Voltage Output 8-/10-/12-Bit DACs in 10-Lead Packages AD5304/AD5314/AD5324 FEATURES GENERAL DESCRIPTION AD5304: 4 buffered 8-Bit DACs in 10-lead MSOP The AD5304/AD5314/AD53241 are quad 8-, 10-, and 12-bit and 10-lead LFCSP buffered voltage output DACs in 10-lead MSOP and 10-lead A Version: ±1 LSB INL, B Version: ±0.625 LSB INL LFCSP packages that operate from a single 2.5 V to 5.5 V supply, AD5314: 4 buffered 10-Bit DACs in 10-lead MSOP consuming 500 A at 3 V. Their on-chip output amplifiers allow and 10-lead LFCSP rail-to-rail output swing to be achieved with a slew rate of 0.7 V/s. A Version: ±4 LSB INL, B Version: ±2.5 LSB INL A 3-wire serial interface is used; it operates at clock rates up to AD5324: 4 buffered 12-Bit DACs in 10-lead MSOP 30 MHz and is compatible with standard SPI, QSPI, MICROWIRE, and 10-lead LFCSP and DSP interface standards. A Version: ±16 LSB INL, B Version: ±10 LSB INL The references for the four DACs are derived from one reference Low power operation: 500 A @ 3 V, 600 A @ 5 V pin. The outputs of all DACs can be updated simultaneously using 2.5 V to 5.5 V power supply the software LDAC function. The parts incorporate a power-on Guaranteed monotonic by design over all codes reset circuit, and ensure that the DAC outputs power up to 0 V Power-down to 80 nA @ 3 V, 200 nA @ 5 V and remains there until a valid write takes place to the device. Double-buffered input logic The parts contain a power-down feature that reduces the current Output range: 0 V to VREF consumption of the device to 200 nA @ 5 V (80 nA @ 3 V). Power-on reset to 0 V Simultaneous update of outputs (LDAC function) The low power consumption of these parts in normal operation Low power-, SPI®-, QSPITM-, MICROWIRETM-, and DSP- makes them ideally suited to portable battery-operated equipment. compatible 3-wire serial interface The power consumption is 3 mW at 5 V, 1.5 mW at 3 V, reducing On-chip, rail-to-rail output buffer amplifiers to 1 W in power-down mode. Temperature range ­40°C to +105°C 1 Protected by U.S. Patent No. 5,969,657; other patents pending.
