Frequently Asked Questions
What is the output resolution of the MCP48FEB28-20E/ST, and how does it affect precision?
The MCP48FEB28-20E/ST provides 12-bit resolution across each DAC channel, yielding 4096 discrete output levels. Combined with a maximum linearity error of 0.14648%, it delivers precise analog outputs suitable for calibration references, trim DAC applications, and fine-grained actuator control in industrial systems.
How many independent DAC channels does the MCP48FEB28-20E/ST provide over a single SPI bus?
The MCP48FEB28-20E/ST integrates 2 independent DAC channels, both controlled via a single 4-wire SPI serial interface. This dual-output architecture reduces component count and PCB routing complexity compared to using two separate single-channel DACs, saving approximately 50% of the board area for the DAC function.
Which package does the MCP48FEB28-20E/ST use, and how many pins does it have?
The MCP48FEB28-20E/ST comes in a TSSOP-20 package with 20 pins. The thin shrink small-outline footprint measures only a few millimeters on each side, making it a compact choice for battery-powered portable instruments and multi-channel analog signal conditioning boards where board space is at a premium.
For which types of embedded applications is the MCP48FEB28-20E/ST most appropriate?
The MCP48FEB28-20E/ST suits applications requiring dual-channel 12-bit analog outputs with SPI control, including programmable power supply voltage references, industrial PID set-point generation, audio bias trimming, and sensor excitation voltage control in systems operating from 3.3 V or 5 V rails.
