MCP47FVB18T-16E/ST

Digital To Analog Converters Overview

The MCP47FVB18T-16E/ST is an octal-channel, 10-bit digital-to-analog converter (DAC) manufactured by Microchip Technology. It features a buffered voltage output and utilizes an I2C interface for communication. The device operates on a single supply voltage ranging from 1.8 V to 5.5 V for both analog and digital domains. It employs an R-2R resistor ladder structure and includes nonvolatile EEPROM memory for data retention. Key performance metrics include a settling time of 7.8 µs, a differential nonlinearity (DNL) of ±0.05 LSB, and an integral nonlinearity (INL) of ±0.4 LSB. The component is housed in a TSSOP-16 package and supports operation across a temperature range of -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Octal channel configuration providing eight independent analog outputs within a single integrated circuit.
• Nonvolatile EEPROM storage retains DAC output values during power-down or system resets.
• Integrated voltage buffer amplifiers drive capacitive loads without requiring external components.
• Standard two-wire I2C serial interface simplifies system connectivity and reduces pin count.

Digital To Analog Converters Applications

• Multi-zone industrial process control systems requiring simultaneous analog adjustments.
• Portable instrumentation with multiple sensor signal conditioning paths.
• Automotive infotainment and display backlight brightness control arrays.
• Test and measurement equipment needing precise multi-channel reference voltages.

Digital To Analog Converters Procurement Notes

Verify the specific suffix and tape-and-reel quantity requirements against the manufacturer's current datasheet before ordering. Confirm that the I2C address configuration matches the system design constraints. Ensure the operating voltage range aligns with the target application's power supply specifications. Check for any recent product change notifications that may affect packaging or material compliance status.

Digital To Analog Converters Selection Notes

Select this component when multiple low-cost, moderate-resolution analog outputs are required in a compact footprint. The I2C interface is suitable for systems where pin count is limited but speed requirements are modest. Consider the nonvolatile memory feature if power loss data retention is critical. Evaluate the thermal performance within the TSSOP-16 package for the intended ambient temperature conditions.

Digital To Analog Converters Part Context

This part belongs to Microchip's MCP47 family of digital-to-analog converters, which offers various channel counts and resolutions. The 'F' designation typically indicates the inclusion of nonvolatile EEPROM memory. The 'VB' suffix denotes the presence of internal voltage buffers. The '18' refers to the 10-bit resolution, while 'T-16E/ST' specifies the tape-and-reel packaging in a 16-pin TSSOP body.

Digital To Analog Converters Replacement Considerations

Direct replacements must match the octal channel count, 10-bit resolution, I2C interface, and TSSOP-16 package. Verify that substitute parts offer comparable DNL/INL specifications and operating voltage ranges. Ensure the replacement maintains the nonvolatile memory feature if power-down retention is required. Cross-reference pinouts to confirm compatibility with existing PCB layouts.
