MAXIM INTEGRATED / ANALOG DEVICES MAX1932ETC APD bias supply
The MAX1932ETC+ is a digitally controlled, highly accurate (±0.5%) APD bias supply in a 12-pin TQFN package. It provides a low-noise, high-voltage output designed to bias avalanche photodiodes (APDs) used in optical receivers. Its architecture ensures minimal output ripple and noise by employing a constant frequency PWM boost topology with a feedback loop that can include an RC or LC filter. The output voltage can be precisely configured through external resistors, an internal 8-bit DAC, an external DAC, or other voltage sources, optimizing resolution for applications requiring specific voltage ranges such as 4.5V to 15V, 4.5V to 45V, 20V to 60V, or 40V to 90V. Safety features include high-side current limiting, avalanche indicator flag, and protection against adverse conditions, making it suitable for optical communications, fiber optic equipment, telecom systems, laser range finders, and PIN diode biasing. It operates from a supply voltage of 2.7V to 5.5V, with a typical supply current of 1mA over -40°C to 85°C. The device features an integrated precision reference and error amplifier, offers output adjustment via an SPI-compatible interface, and boasts a compact footprint for space-constrained designs. Its switching frequency is adjustable between 240kHz and 360kHz, supporting a range of high-accuracy biasing applications.
