AD5372BCPZ

AD5372 is a 32-channel, 16bit, serial input, voltage output DAC. The device provides buffered voltage outputs with a nominal span of 4× the reference voltage. The gain and offset of each DAC can be independently trimmed to remove errors. For even greater flexibility, the device is divided into four groups of eight DACs. Two offset DACs allow the output range of the groups to be altered. It has a high-speed serial interface that is compatible with SPI, QSPI™, MICROWIRE™, and DSP interface standards and can handle clock speeds of up to 50MHz. The DAC registers are updated on reception of new data. All the outputs can be updated simultaneously by taking the active-low LDAC input low. Each channel has a programmable gain and an offset adjust register. Typical applications are level setting in automatic test equipment (ATE), variable optical attenuators (VOA), optical switches, industrial control systems, instrumentation.

• System calibration function allowing user-programmable offset and gain
• Channel grouping and addressing features, thermal shutdown function
• DSP/microcontroller-compatible serial interface, SPI serial interface
• 2.5V to 5.5V JEDEC-compliant digital levels, digital reset (active-low RESET)
• Clear function to user-defined SIGGNDx, simultaneous update of DAC outputs
• 4 × VREF (12V) nominal output span, 32 output channels, ±4 linearity error (LSB)
• Gain error is 0.1% FSR (DVCC=2.5V to 5.5V; VDD=9V to 16.5V; VSS=-16.5V to -8V)
• VOUTx temperature coefficient is 5ppm FSR/°C typ (VDD=9V to 16.5V; VSS=-16.5V to -8V)
• 64-lead frame chip scale package (LFCSP-VQ)
• Temperature rating range from -40°C to +85°C
