This datasheet describes the Analog Devices AD5380, a complete single-supply 40-channel 14-bit denseDAC with rail-to-rail output amplifiers.
The AD5380 is a complete single-supply, 40-channel, 14-bit denseDAC featuring 100-pin LQFP packaging. All 40 channels include an internal output amplifier operating in a rail-to-rail manner. The device incorporates a programmable 1.25 V/2.5 V reference voltage source with 10 ppm/°C accuracy and channel monitoring functionality that multiplexes analog outputs to a shared MON_OUT pin for external monitoring. This manual is written in Chinese.
