- 0.146% maximum linearity error enabling precise analog output calibration in multi-channel industrial systems
- I2C serial interface with binary input format allowing bus-shared control of all 8 channels with minimal wiring
- Compact QFN-20 package with 20 pins enabling dense PCB layouts for multi-output analog control boards
Applications
The MCP47FEB28T-E/MQ suits multi-axis motor control, industrial process controllers, and programmable power supplies requiring 8 simultaneous independent analog outputs. Its 12-bit resolution and EEPROM retention ensure each channel holds its calibrated setpoint without host re-initialization after a power cycle. The device is also used in optical transceiver biasing and test equipment that demand precise, stable, multi-channel voltage references.

Frequently Asked Questions
How does the MCP47FEB28T-E/MQ handle power loss without losing its output settings?
The device integrates EEPROM memory that stores all 8 channel DAC codes non-volatilely. On power-up, each channel automatically restores its last programmed 12-bit output value without needing the host MCU to re-send configuration, making it ideal for industrial systems that must resume normal analog outputs immediately after a power interruption.
What linearity accuracy does MCP47FEB28T-E/MQ offer across its 8 channels?
The MCP47FEB28T-E/MQ guarantees a maximum integral linearity error of 0.146484375% across all 8 output channels. For a 12-bit converter with 4096 steps, this corresponds to roughly ±6 LSB worst-case, which is sufficient for calibration and bias-setting tasks in multi-channel process control or sensor excitation circuits.
For a QFN-20 layout, what footprint does the MCP47FEB28T-E/MQ require on a PCB?
The MCP47FEB28T-E/MQ uses a QFN-20 (S-PQCC-N20) package with 20 pins. QFN-20 packages typically measure 4 mm × 4 mm with exposed thermal pad, providing a very compact PCB footprint that reduces board area compared to SOIC alternatives while also improving thermal dissipation in dense multi-channel analog boards.
What is the standard factory lead time for MCP47FEB28T-E/MQ and when was it introduced?
The MCP47FEB28T-E/MQ carries a standard factory lead time of 15 weeks, which designers should factor into procurement timelines for production builds. The device was introduced on 2020-06-22 and is an active product, making it suitable for new designs needing an octal 12-bit DAC with EEPROM over I2C.
