BH2226FV-E2

Digital To Analog Converters Overview

The BH2226FV-E2 is an 8-bit, 8-channel digital-to-analog converter (DAC) manufactured by ROHM Semiconductor. It utilizes an R-2R resistor ladder architecture to provide voltage outputs with a settling time of 100 µs. The device operates on a single power supply ranging from 2.7 V to 5.5 V for both analog and digital sections. It features a 3-wire serial interface compatible with CMOS logic levels. Key performance metrics include a differential nonlinearity (DNL) of ±1 LSB and integral nonlinearity (INL) of ±1.5 LSB. The component is housed in a compact 16-pin SSOP package and functions within a temperature range of -20°C to +85°C.

Digital To Analog Converters Feature Summary

• Integrates eight independent 8-bit DAC channels within a single integrated circuit.
• Supports standard 3-wire serial communication interfaces for simplified system connectivity.
• Operates reliably across a wide single-supply voltage range suitable for low-power applications.

Digital To Analog Converters Applications

• Portable electronic devices requiring multi-channel signal generation
• Battery-powered instrumentation systems
• Consumer electronics utilizing low-voltage logic control

Digital To Analog Converters Procurement Notes

Verify the specific suffix E2 against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Ensure the ordering code matches the required tape-and-reel or cut-tape packaging format. Cross-reference the lot date code with project timelines to avoid obsolescence risks associated with older manufacturing runs.

Digital To Analog Converters Selection Notes

Select this component when multiple low-resolution analog outputs are needed without external multiplexing. Compare channel count requirements against similar models like the BH2228FV-E2 if fewer channels suffice. Verify that the 100 µs settling time meets the system's update rate specifications before finalizing the design.

Digital To Analog Converters Part Context

This part belongs to the BH2226FV series of multi-channel DACs from ROHM. It shares architectural similarities with other members of the family but is distinct in its 8-channel configuration and 16-pin SSOP footprint. It serves as a cost-effective solution for applications needing several analog outputs from a single microcontroller.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same series include parts with different channel counts such as the BH2228FV-E2 (6-channel) or BH2223FV-E2 (10-channel). Verify pin compatibility and electrical parameters before swapping, as package variations may exist across the product line.
