AD5383BSTZ-3

ANALOG DEVICES  AD5383BSTZ-3  数模转换器, 12 bit, 167 kSPS, 并行、串行, 2.7V 至 3.6V, LQFP, 100 引脚

GENERAL DESCRIPTION

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.

•  I2C-compatible interface that supports a 400 kHz datatransfer rate.
