Signal line and supply filtering
There are many reasons for needing to filter power supply or signal line. Power supply lines from a switching regulator may be too noisy for sensitive analog circuitry. Signal or power supply lines may pick up interference either from the rest of the system circuitry or from external devices. With signal lines the problem of […]
Audio op amp puts out 150 mW
Texas Instruments introduced an audio operational amplifier (op amp) that sets the latest standard in audio performance. The OPA1622 is the newest addition to the company’s Burr-Brown™ Audio line and is the next generation of the widely adopted OPA1612. The new OPA1622 delivers high output power of up to 150 mW and extremely low distortion […]
