BH2226FV,BH2226F is an 8bit R-2R-type D/A converter with 8 channels from ROHM. It supports serial/parallel conversion and has a built-in RESET function. It has a wide voltage range of 2.7V-5.5V to meet different design requirements.
The BH2226FV and BH2226F are 8‑bit R‑2R type D/A converters with eight independent channels. They feature a built‑in reset function that forces all outputs low on power‑up and support both serial and parallel data interfaces.
Key specifications include a wide supply voltage range of 2.7 V to 5.5 V, low current consumption (1.3 mA), fast settling time (100 µs), and a 10 MHz data transfer rate. The device is offered in SSOP‑B16 and SOP16 packages and is intended for use in audio‑visual, office‑automation, communication, and consumer electronic equipment.
| Power source voltage range | 2.7 V – 5.5 V |
|---|---|
| Number of channels | 8 |
| Current consumption | 1.3 mA |
| Integral non‑linearity (INL) | ±1.5 LSB |
| Settling time | 100 µs |
| Data transfer frequency | 10 MHz |

The device operates from 2.7 V up to 5.5 V.
Each part provides eight independent channels.
It ensures that the output voltage on all channels is low during power‑up.
A control command consists of three lines of 12‑bit serial data, with DI sampled on the rising edge of CLK.
