Maintains Stable Bias Current in N-Type Discrete Bipolar Junction and Field Effect Transistors, Provides Stable Bias Using a Single Component Without Use of Emitter Ballast and Bypass Components, Operates Over a Wide Range of Supply Voltages Down to 1.8 Vdc.

The TS472 is a differential-input microphone preamplifier optimized for high-performance, PDA and notebook audio systems. This device features an adjustable gain from 0dB to 40dB with excellent power-supply and common-mode rejection ratios. In addition, the TS472 has a very low-noise microphone bias generator of 2V. It also includes a complete shutdown function, with active low standby mode.

DESCRIPTION 75V DC/DC Converterfor APD BiasThe LT3571 is a current mode step-up DC/DC converter designed to bias avalanche photodiodes (APDs) in optical receivers with an output voltage up to 75V. The LT3571 features a high side xed voltage drop APD current monitor with better than 10% relative accuracy over the entire temperature range. The integrated power switch, Schottky diode and APD current monitor allow a small solution footprint and low solution cost. It combines a traditional voltage lo

Sirenza Microdevices' SGC-4486Z is a high performance SiGe HBT MMIC amplifier utilizing a Darlington configuration with a patented active bias network. The active bias network provides stable current over temperature and process Beta variations. Designed to run directly from a 3V supply, the SGC-4486Z does not require a dropping resistor as compared to typical Darlington amplifiers. The SGC-4486Z is designed for high linearity 3V gain block applications that require small size and minimal ex

The MA4SW610B-1 is a Reflective SP6T Series-Shunt broad band switch with integrated bias networks made with M/A-COM's HMICTM (Heterolithic Microwave Integrated Circuit) process, US Patent 5,268,310. This process allows the incorporation of silicon pedestals that form series and shunt diodes or vias by imbedding them in low loss, low dispersion glass. By using small spacing between elements, this combination of silicon and glass gives HMIC devices low loss and high isolation performance throu
