AD51070 |
Elite Semiconductor Microelectronics Technology (ESMT) launches the analog-input automotive audio amplifier - AD51070. - This product can drive a mono channel at 1×22W. - Spread spectrum technology supports extremely low EMI noise. It is an automotive audio amplifier compliant with the AEC-Q100 standard |
|
AD81140 |
The AD81140 is a pulse-code modulation (PCM) input Class-D power amplifier featuring high efficiency. - Supports standard I2S and 8-channel time-division multiplexing (TDM) technology, and can receive sampling rates from 8KHz to 96KHz. - The IC eliminates the need for an external MCLK signal in PCM communication, which helps reduce EMI and PCB coupling issues while also minimizing board size and IC pin count. - Built-in spread spectrum technology enhances anti-interference capability, improves privacy, and reduces electromagnetic interference (EMI) by dispersing the signal's spectrum across a frequency band wider than its original width. |
|
EML3470 |
The EML3470 is a synchronous buck converter supporting a 4.5V to 18V power input and a 3A output. - The main advantage of the pulse skipping modulation (PSM) mode is that it significantly improves conversion efficiency under light-load conditions. - Supports the constant-on-time (COT) control architecture. - The main advantages include ultra-fast load transient response (no waiting for clock cycles), elimination of complex loop compensation design (simplifying design), high light-load efficiency (PFM mode), and fewer required components. |
