DAC7553IRGTT

ЦАП, двойной, 12 бит, 1 Мвыборок/с, Последовательный, 2.7В до 5.5В, QFN, 16 вывод(-ов).

The DAC7553IRGTT is a 2-channel 12-bit voltage-output Digital-to-analog Converter (DAC) with exceptional linearity and monotonicity. Its proprietary architecture minimizes undesired transients such as code-to-code glitch and channel-to-channel crosstalk. The low-power DAC7553 operates from a single 2.7 to 5.5V supply. The DAC7553 output amplifiers can drive a 2kR, 200pF load rail-to-rail with 5µs settling time, the output range is set using an external voltage reference. The 3-wire serial interface operates at clock rates up to 50MHz and is compatible with SPI, QSPI, MICROWIRE and DSP interface standards. The outputs of DAC may be updated simultaneously or sequentially. The part incorporates a power-on-reset circuit to ensure that the DAC outputs power up at midscale and remain there until a valid write cycle to the device takes place. The part contains a power-down feature that reduces the current consumption of the device to under 2µA.
