SA57251-28GW - Brand New PHILIPS IC Chips
-
Description
The SA57251-28GW is a dual-channel, high-performance gain control circuit designed for dynamic range compression or expansion. This electronic component is equipped with a full-wave rectifier to detect the average value of the input signal, a linearized, temperature-compensated variable gain cell (∆G), and a dynamic time constant buffer. With these features, it offers improved low frequency gain control ripple distortion and allows for independent control of dynamic attack and recovery time. The SA57251-28GW operates within a wide dynamic range of greater than 110dB and has a low noise level of 6µV. It also has a wide supply voltage range of 6V-22V, making it versatile for various applications.
