Variable Transformer DC Power Supplies
-
Variable DC power supplies are AC to DC power supplies with a variable DC output. The output can be varied with a Variable Transformer (also known as variac). The Variable Transformer can be adjusted manually or with a motorized control. The AC input power can be single phase or three phases. With single phase AC input, the DC output ripple is very high (50%). With three phase AC input, the DC output ripple is low (5%). This would be a key benefit for selecting three phase AC input instead of single phase.

Multiplying Current Output D/A Converters
-
Analog Devices offers a wide range of high precision, multiplying current output (IOUT) D/A converters (DACs) that feature ±1 LSB INL and DNL specifications, from 12-bit up to an industry-leading 18-bit resolution. Our portfolio includes single and multiple D/A converters in small packages with parallel or serial SPI interfaces. Multiplying current output R-2R D/A converters allow for an external amplifier that’s optimized for specific applications and that does not require reference buffering, which enables high linearity. The SoftSpan™ feature allows software selectable output spans, therefore eliminating the need to add precision gain stages and the associated external jumpers, precision resistors, and amplifier circuitry. Integrated precision resistors allow for reference inversion, bipolar offset, and offset and gain adjustment.
