BA7622F-E2

Overview

The BA7622F-E2 is a high-performance video driver IC from Rohm Semiconductor, designed for consumer video equipment. It integrates three independent circuits within an 8-SOP package. The device operates on a supply voltage ranging from 4.5 V to 5.5 V and draws a typical circuit current of 23.6 mA at 5 V. Each output channel can drive two parallel 75 Ω loads simultaneously. The IC features built-in sync-tip clamp inputs and bias inputs with internal resistances of 20 kΩ, allowing it to handle Y signals, C signals, and composite video signals concurrently.

Feature Summary

• Integrates three video driver circuits capable of driving dual 75 Ω loads per output.
• Includes built-in sync-tip clamp input circuits and one bias input circuit.
• Supports simultaneous processing of Y signals, C signals, and composite video signals.
• Features protection circuitry that activates power save mode when outputs are forced to ground.

Applications

• TV sets
• VCRs
• Camcorders

Procurement Notes

Verify the component status before integration, as this specific part number may be discontinued or subject to end-of-life notifications. Confirm that the 8-SOP tape and reel packaging aligns with your assembly line requirements. Ensure that the operating temperature range of -25°C to +75°C meets your environmental specifications. Cross-reference the datasheet revision date to ensure compatibility with your design constraints.

Selection Notes

Select the BA7622F-E2 when a single chip solution is required to process multiple video signal types including composite, Y, and C signals. This component is suitable for designs needing direct connection to 2Vpp output type signal processing LSIs and DACs. Consider its low power consumption and small SOP-8 footprint for space-constrained portable or compact consumer electronics applications.

Part Context

This component belongs to the BA7622/BA7623 series of standard 3-output video drivers developed by Rohm Semiconductor. While the BA7623 variant allows direct base connection without clamping, the BA7622F specifically incorporates dedicated clamp and bias inputs. Both share similar electrical characteristics and physical packaging, differing primarily in their input signal conditioning architecture.
