Description :
GENERAL DESCRIPTION
The AD5380 is a complete, single-supply, 40-channel, 14-bit denseDAC® available in a 100-lead LQFP package. All 40 channels have an on-chip output amplifier with rail-to-rail operation. The AD5380 includes a programmable internal 1.25 V/2.5 V, 1 0 ppm/°C reference, an on-chip channel monitor function that multiplexes the analog outputs to a common MON_OUT pin for external monitoring, and an output amplifier boost mode that allows optimization of the amplifier slew rate. The AD5380 contains a double-buffered parallel interface that features a 20 ns WR pulse width, an SPI-, QSPI-, -MICROWIRE, -DSP compatible serial interface with interface speeds in excess of 30 MHz, and an I2 C-compatible interface that supports a 400 kHz data transfer rate.
