Today, I tried to use a ULN2003a darlington array as a buffer for my CPLD's outputs. While it works well, I have a concern. The max. voltage where the Max V is guaranteed to read a low is 0.8V. The ...
I wonder if is necessary to put a buffer before a FFT block. I want to do a fft, with N = 16 (samples). Is necessary to design a temporal memory system to save 16 samples before loading into FFT or ...
I would like to make a buffer in system generator to use it with a FFT block. I want to charge 16 values to a FFT block from another system I´ve designed and I need a temporary memory system. Could ...
I'm looking for a three-state inverting octal buffer for a replacement part for an old microprocessor lab. The package should be DIP. Ucc should be on pin 20. Chip select should be at pins 1 and 19 ...
I have a pair of small battery-operated self-logging 3-axis accelerometer devices that each use a microSD flash device for storage (the GCDC X250-2). Unfortunately, the devices do not buffer microSD ...
I need to buffer an input signal such that I do not load down the source, which is a 100k resistor. However, I need to buffer at least 6 channels, and for more advanced models I'd like to move to 10 ...
I designing a circuit will store log data to an SD card. The information will be coming form a parent circuit that this one plugs into. The parent circuit will supply 5V to my daughter card. The ...
I need to buffer an audio signal (feeding into a variable input impedance), and make it mutable with a digital control. The best thing I can think of is an op-amp (maybe TS971? 3×2 mm SOT23) feeding ...
