Frequently Asked Questions
How does the MCP47FEB28-20E/ST retain DAC output values after power is removed?
The MCP47FEB28-20E/ST integrates EEPROM storage for all 8 DAC channels, so the 12-bit output codes are preserved even when the 2.7 V to 5.5 V supply is interrupted. On power-up, each channel automatically restores its last saved output without requiring a microcontroller to re-initialize the values, reducing startup time and firmware complexity.
What resolution and linearity does the MCP47FEB28-20E/ST provide for analog output accuracy?
The MCP47FEB28-20E/ST delivers 12-bit resolution across all 8 channels, giving 4096 discrete output steps. Maximum linearity error is specified at 0.146484375%, which corresponds to less than 6 LSBs of integral nonlinearity, suitable for precision calibration circuits in medical equipment and industrial sensor conditioning where tight output accuracy is required.
Can multiple MCP47FEB28-20E/ST devices share the same I2C bus in a design?
Yes. The MCP47FEB28-20E/ST supports configurable I2C addresses via address pins, allowing multiple devices to coexist on a single 2-wire bus operating up to 400 kHz in Fast Mode. This enables a designer to control 16 or more DAC channels from one microcontroller bus, which is useful in multi-zone temperature control and multi-channel bias generation systems.
What package does the MCP47FEB28-20E/ST use and how does it affect PCB layout?
The device comes in a 20-pin TSSOP package with a pin pitch of 0.65 mm, giving a body width of approximately 4.4 mm. This small footprint is advantageous in compact PCB designs such as rack-mount instruments and handheld calibrators. The fine pitch requires good solder paste control during assembly but keeps the board area for 8 analog output channels under 30 mm².
