Overview
The AD5370BCPZ, produced by Analog Devices Inc., is a 40-channel, 16-bit, serial input, voltage-output digital-to-analog converter (DAC). This device is packaged in a 64-lead LFCSP (Lead Frame Chip Scale Package) and offers a high degree of flexibility and precision. The AD5370 contains forty 16-bit DACs, each providing buffered voltage outputs with a span that is 4× the reference voltage. The device is designed to operate over a wide supply range, from VSS of −16.5 V to −4.5 V and VDD from +9 V to +16.5 V, making it suitable for a variety of applications requiring precise voltage control.

Key Features
- High-speed serial interface compatible with SPI, QSPI, MICROWIRE, and DSP interface standards, with clock speeds up to 50 MHz.
- Each channel has programmable gain and offset adjust registers to remove gain and offset errors.
- The device is divided into five groups of eight DACs, with three offset DAC channels to adjust the output range of blocks.
- Buffered voltage outputs with respect to an external SIGGNDx input, and the ability to switch DAC outputs to SIGGNDx via the CLR pin.
- System calibration function allowing user-programmable offset and gain.
- Thermal shutdown function and digital reset (RESET) with clear function.
- Simultaneous update of DAC outputs by taking the LDAC input low.
Applications
- Level setting in automatic test equipment (ATE).
- Variable optical attenuators (VOA) and optical switches.
- Industrial control systems.
- Instrumentation.
