BH2223GLU-E2

Digital To Analog Converters Overview

The BH2223GLU-E2 is an 8-bit, 10-channel digital-to-analog converter manufactured by ROHM Semiconductor. It utilizes an R-2R resistor ladder architecture and features a 3-wire serial interface for independent channel control via microcontrollers. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports a clock frequency up to 1.0 MHz. It incorporates a power-on reset circuit to ensure stable low output states upon initialization. The component is housed in an SSOP-B16 surface-mount package.

Digital To Analog Converters Feature Summary

• Eight-bit resolution across ten independent analog output channels using an R-2R conversion system.
• Three-wire serial interface allowing direct connection to microcontrollers for data input and clocking.
• Integrated power-on reset circuitry that forces outputs to a low state immediately after power application.
• Rail-to-rail output capability generating full-scale voltage ranges without signal loss.

Digital To Analog Converters Applications

• Electronic adjustment for Digital Video Cameras (DVC).
• Voltage tuning for Digital Still Cameras (DSC).
• General-purpose analog voltage level setting in consumer electronics.

Digital To Analog Converters Procurement Notes

Verify the specific suffix against the manufacturer's current product status, as availability may vary. Confirm the package type matches the design requirements, as the datasheet indicates multiple package options exist within the series. Ensure peripheral components support the specified operating temperature range and load capacitance limits during integration.

Digital To Analog Converters Selection Notes

Select this component when a multi-channel DAC with low pin count is required for cost-sensitive applications. The 3-wire interface minimizes microcontroller I/O usage compared to parallel alternatives. Verify that the 8-bit resolution meets the precision requirements of the target application, as higher resolution options are available in other series.

Digital To Analog Converters Part Context

This part belongs to the BH2223FV/GLU family of standard ICs designed for electronic adjustment tasks. It shares core architectural similarities with the BH2223FV variant but differs in physical packaging. The GLU suffix typically denotes the SSOP-B16 package configuration, distinguishing it from the VFLGA28 option while maintaining identical electrical performance characteristics.

Digital To Analog Converters Replacement Considerations

The BH2223FV serves as a functional equivalent within the same series. Substitution requires verifying package compatibility, as the FV variant may utilize the VFLGA28 package. Electrical parameters remain consistent between variants, ensuring direct interchangeability if the footprint allows.
