Product Summary

The MAX1932ETC+T is a digitally Controlled, 0.5% Accurate, Safest APD Bias Supply. The MAX1932ETC+T generates a low-noise, high-voltage output to bias avalanche photodiodes (APDs) in optical receivers. Very low output ripple and noise is achieved by a constant-frequency, pulse-width modulated (PWM) boost topology combined with a unique architecture that maintains regulation with an optional RC or LC post filter inside its feedback loop. A precision reference and error amplifier maintain 0.5% output voltage accuracy. The applications of the MAX1932ETC+T include Optical Receivers and Modules, Fiber Optic Network Equipment, Telecom Equipment, Laser Range Finders and PIN Diode Bias Supply.
