32通道3伏/5伏單電源12位密集數(shù)模轉(zhuǎn)換器AD5383數(shù)據(jù)表

　　The AD5383 is a complete， single-supply， 32-channel， 12-bit denseDAC? available in a 100-lead LQFP package. All 32 channels have an on-chip output amplifier with rail-to-rail operation. The AD5383 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 AD5383 features ? Double-buffered parallel interface with a 20 ns WR pulse width. ? SPI-/QSPI-/MICROWIRE-/DSP-compatible serial interface with interface speeds in excess of 30 MHz. ? I 2 C-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 independently 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 channel. With boost off， power consumption is typically 0.25 mA/channel.
