Frequently Asked Questions
How many analog output channels does MCP48FVB08-20E/ST provide, and what resolution do they offer?
MCP48FVB08-20E/ST provides 8 independent analog output channels, each with 8-bit resolution giving 256 discrete output levels. The maximum linearity error is 0.1953%, ensuring consistent output accuracy across all channels. This makes it practical for multi-axis motor control, multi-zone temperature setpoint generation, and similar applications requiring simultaneous independent analog control.
Why choose a volatile DAC like MCP48FVB08-20E/ST over a non-volatile alternative for a real-time control system?
Volatile DACs such as MCP48FVB08-20E/ST update output registers instantly on each SPI write without the wear and latency of EEPROM write cycles, which can take up to 5 ms in non-volatile devices. For closed-loop control systems that update DAC outputs at rates of 1 kHz or more, the volatile architecture is essential. The trade-off is that output values reset to zero on power-down, so the host MCU must reinitialize the 8 channels at startup.
What SPI clock rate does MCP48FVB08-20E/ST support for high-throughput multi-channel updates?
MCP48FVB08-20E/ST supports SPI clock frequencies up to 20 MHz, allowing the host controller to update all 8 DAC channels rapidly. At 20 MHz clock with 16-bit SPI transfers per channel, a full 8-channel refresh takes approximately 6.4 µs, enabling control loop rates well above 100 kHz for demanding real-time analog output applications.
