Description

The Model 429A and 429B,an extremely fast multiplier/divider,should be considered if bandwidth, temperature coefficient, or accuracy are critical parameters. Based on the transconductance principle to achieve high speed, the model 4429A and 429B offers a unique combination of features, those being  1/2% max error (429B) and 10MHz small signal bandwidth

Both models 429A and 429B are internally trimmed achieving max errors of 1.0% and 0.5 % respectively. By fine trimming the offset and feedthrough with external trim potentiometers typical performance may be improved to 0.5% for the 429A and 0.2% for the 429B.In addition to high accuracy and high bandwidth, the model 429A and 429B offers exceptionally good stability for changes in ambient temperature. Model 429B is 100% temperature tested in order to guarantee an overall accuracy temperature coefficient of only 0.04%/"C max. Additionally, offset drift is held to only I mV/°C max. To satisfy OEM requirements of low cost, the 429A and 429B uses transconductance principles with the latest design techniques and components to achieve guaranteed performance at competitive prices.
