ANALOG DEVICES  AD5380BSTZ-3  数模转换器, 14 bit, 400 kSPS, 并行、串行, 2.7V 至 3.6V, LQFP, 100 引脚

Product Details

The AD5380 is a complete, single-supply, 40-channel, 14-bit DAC 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, 10 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 I2C-compatible interface that supports a 400 kHz data transfer rate.

An input register followed by a DAC register provides double buffering, allowing the DAC outputs to be updated indepen-dently or simultaneously using the LDAC input.

Each channel has a programmable gain and offset adjust register that allows the user to fully calibrate any DAC chan-nel. Power consumption is typically 0.25 mA/channel with boost off.
