Analog Devices AD5381 40-Channel 12-Bit DAC Data Sheet
The AD5381 is a complete, single-supply, 40-channel, 12-bit dense DAC available in a 100-lead LQFP package. All 40 channels feature an on-chip output amplifier with rail-to-rail operation. The device includes a programmable internal 1.25 V/2.5 V, 10 ppm/°C reference, an on-chip channel monitor function, and an output amplifier boost mode to optimize slew rate.
The AD5381 contains a double-buffered parallel interface featuring a 20 ns WR pulse width, an SPI-/QSPI-/MICROWIRE-/DSP-compatible serial interface with speeds in excess of 30 MHz, and an I2C-compatible interface supporting a 400 kHz data transfer rate. Power consumption is typically 0.25 mA/channel with boost mode disabled.
