DAC TRANSFORMERS

We offer a range of  transformers suitable for most Digital to Analogue Converters (DAC's). Multi-section winding techniques are used to maximize bandwidth and transient response. All our DAC transformers are constructed on Mumetal (76% Nickel) cores for minimal distortion and contained in heavy gauge Mumetal screening cans. Some models have multiple internal electrostatic shields are provided to minimize noise pick-up.

Types 9055 and 9545 have twin bifilar primary windings which may be used in parallel driven from one DAC or may be used with twin DAC's carrying out of phase signals. These are subtracted by the transformer which provides the ultimate in cancellation of quantisation noise.

Types 8347 and 9055 are offered for DAC's with up to 0.6 mA dc offset. Most modern DACs do not have significant dc offset.
