2021年1月13日 · I am building a power amp with the chip LME49830 as driver stage for IRFP240/IRFP9240 mosfet quads, it's going to be used for bi-amping to drive the woofers of …

2012年10月4日 · LT1166+LME49830 design by Bob Cordell Hi Vic, Take a look at my layout in this thread, LME49830+LatFET, yet another for design review. there is an optimal position for …

I designed a LME49830 with foldback current limit and the popular 2sk1530/2sj201, the circuit is similar to the an1850 from ti. Unfortunately I can only simulate the circuit in tina-ti because I …

This connection completes the return path to feedback the output voltage to the mute gain circuitry inside LME49830. If the Osense pin is not connected to the output or it is floated, high …

2011年9月20日 · the IC is a very nice circuit, unfortunately the LME is obsolete since not so long time 🙁 seems that TI wanted to sell more of their own class D solutions instead of the old school …

2016年11月27日 · Hello, I want to build a Mos-Fet (single-ended / high-voltage / medium-power) amplifier with the Texas Instruments LME49830 driver : in my application, I just have to cope …

2009年4月29日 · Now I have enough plug-in driver boards to do LME498xx comparison efficiently. Three driver boards will be prepared for working with two pairs of …

2014年4月28日 · The LME49830 is designed for use with MOSFETs. I suspect most of the chip is identical to the LME49810 or LME49811, but the circuit that biases the output stage is …

2010年9月4日 · This is an implementation of National's reference design for LME49830 with two matched pairs of 2SK1530+2SJ201 per channel. The PCBs were made using National's …

2009年2月9日 · Nick. Preliminary - the schematics is based on an original National's file and a 1/2 LM833 , 2 bypass electrolytic for the LME49830 and 2 for LM833. 2 outputs through resistors …
