AC/DC modules integrate LED-driving control circuits, switching elements, isolation transformers and constant-current circuits into a single SIL package.
Rohm's BU2501FV 8bit 12-channel DAC is designed for operation with a 3V supply voltage.
The 10bit 10-channel BU2505FV DAC uses a 5V supply.
Both convertors offer a TTL-compatible digital input, while each channel output incorporates a rail-to-rail output type buffer amplifier that ensures high-stability operation across the complete voltage range and prevents oscillation, even when using capacitive loads.
The BU2501FV allows 12bit three-wire serial data input and the BU2505FV provides for 14bit three-wire input.
Both DACs can be serially cascaded with other devices of the same type to address the widest possible variety of application requirements.
The new DACs are supplied in compact SSOP-B20 20-pin packages with a board mounting area of just 6.5 x 6.4mm and a low profile of only 1.15mm.
