2.5 V to 5.5 V, 500 A, Quad Voltage Output 8-/10-/12-Bit DACs in 10-Lead Packages Data Sheet AD5304/AD5314/AD5324 FEATURES GENERAL DESCRIPTION 1 The AD5304/AD5314/AD5324 are quad 8-, 10-, and 12-bit AD5304: 4 buffered 8-Bit DACs in 10-lead MSOP and buffered voltage output DACs in 10-lead MSOP and 10-lead 10-lead LFCSP A, W 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 and consuming 500 A at 3 V. Their on-chip output amplifiers 10-lead LFCSP allow rail-to-rail output swing to be achieved with a slew rate of A, W Version: 4 LSB INL, B Version: 2.5 LSB INL 0.7 V/s. A 3-wire serial interface is used it operates at clock AD5324: 4 buffered 12-Bit DACs in 10-lead MSOP and rates up to 30 MHz and is compatible with standard SPI, QSPI, 10-lead LFCSP MICROWIRE, and DSP interface standards. A, W 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 V REF consumption of the device to 200 nA 5 V (80 nA 3 V). Power-on reset to 0 V The low power consumption of these parts in normal operation LDAC Simultaneous update of outputs ( function) makes them ideally suited to portable battery-operated equipment. Low power-, SPI-, QSPI-, MICROWIRE-, and DSP- The power consumption is 3 mW at 5 V, 1.5 mW at 3 V, reducing compatible 3-wire serial interface to 1 W in power-down mode. On-chip, rail-to-rail output buffer amplifiers Temperature range 40C to +105C Qualified for automotive applications APPLICATIONS Portable battery-powered instruments Digital gain and offset adjustment 1 Protected by U.S. Patent No. 5,969,657.
