The CD53D04/CD53D14/CD53D24 are quad 8-, 10- and 12-bit buffered voltage output DACs in MSOP10 packages that operate from a single 2.5V to 5.5V supply, consuming only 500uA at 3V. They have on- chip rail-to-rail output amplifiers with slew rate of 0.7V/us. A 3-wire serial interface compatible with standard SPI, QSPI, MICROWIRE, and DSP interface standards is used, which can operates at clock rates up to 30MHz. The references for the four DACs are derived from one reference pin. The outputs of all DACs can be updated simultaneous. It incorporate a power-on reset circuit, and ensure that the DAC outputs power up to 0V and remains there until a valid write takes place to the device. The parts contain a power- down feature that reduces the current consumption to 200nA@5V (80nA @3V).
