ChatGPT for Hardware Design
I recently used ChatGPT to find a part. Maybe this was an anomalous result, but it was wrong. Don't know if this will be an issue with your project.Me: Is there a digital to analog converter with an 8V analog range and serial input?CGPT: Yes, there are several digital-to-analog converters (DACs) available with an 8V analog range and serial input. One example is the AD5541A DAC from Analog Devices. It has a 16-bit resolution and can accept serial input in the form of SPI or QSPI signals. The output voltage range is programmable and can be set to 0 to 8V using an external reference voltage.Another example is the MAX5389 DAC from Maxim Integrated. It has an 8-bit resolution and can accept serial input in the form of I2C signals. The output voltage range is also programmable and can be set to 0 to 8V using an external reference voltage.These are just a couple of examples, but there are many other DACs available from different manufacturers that meet your specifications.Me: Those parts  are limited to 6v maxCGPT: I apologize for the mistake in my previous response. You are correct that the AD5541A and MAX5389 DACs have a maximum output voltage range of 5V, and they cannot meet your requirement of an 8V analog range.However, there are other DACs that can meet your specifications. For example, the DAC5578 from Texas Instruments is a 16-bit DAC that can operate from a single 5V supply and has a programmable output range up to 10V. It also supports a serial interface with SPI or MICROWIRE protocols.Another option is the MCP49xx series from Microchip, which includes several DACs with output voltage ranges up to 10V and a serial interface with SPI or QSPI protocols.I hope this information is helpful, and please let me know if you have any further questions.
