This is a ROHM ultra-compact, output capacitor-less single output video driver, model BH76906GU, with a 4.5MHz low pass filter and support for low voltage operation
The ROHM BH76906GU, BH76909GU, BH76912GU, BH76916GU and BH76706GU are ultra‑compact, capacitor‑less video driver ICs designed for digital still cameras, mobile phones and other portable devices. They integrate a charge‑pump circuit, built‑in low‑pass filter and standby function, allowing operation from as low as 2.5 V without external coupling capacitors.
Key features include four selectable video‑driver gains (6 dB, 9 dB, 12 dB, 16.5 dB), a maximum output voltage of 5.2 Vpp, and the ability to use the output pin as an input pin on the BH76706GU variant. The note provides absolute maximum ratings, electrical characteristics, pin descriptions, test and application circuit examples, and layout cautions for reliable implementation.
| Supply voltage (absolute max) | 3.55 V |
|---|---|
| Power dissipation (absolute max) | 580 mW |
| Operating temperature range | -40 °C to +85 °C |
| Maximum output voltage | 5.2 Vpp |
| Video driver amplifier gains | 6 dB, 9 dB, 12 dB, 16.5 dB |

The absolute maximum supply voltage is 3.55 V, and the typical operating range is 2.5 V to 3.45 V.
No, the built‑in charge‑pump circuit eliminates the need for an external output coupling capacitor.
The maximum output level is 5.2 Vpp.
Yes, on the BH76706GU variant the output pin can be used as a video input pin.
