Microchip ATSAML22G17A-AUT

ARM® Cortex®-M0+32 МГц128 КБ (128К x 8)

Overview

 • AEC-Q100 Qualified for Automotive Applications – Device Temperature: –55°C to 125°C Ambient – Device HBM Classification Level: ±2500 V – Device CDM Classification Level: ±500 V

 The TAS5414C-Q1 and TAS5424C-Q1 are fourchannel digital audio amplifiers designed for use in automotive head units and external amplifier modules. They provide four channels at 23 W continuously into 4 Ω at less than 1% THD+N from a 14.4-V supply. Each channel can also deliver 38 W into 2 Ω at 1% THD+N. The TAS5414C-Q1 uses single-ended analog inputs, whereas the TAS5424CQ1 employs differential inputs for increased immunity to common-mode system noise. The digital PWM topology of the device provides dramatic improvements in efficiency over traditional linear amplifier solutions. This reduces the power dissipated by the amplifier by a factor of ten under typical music playback conditions. The device incorporates all the functionality needed to perform in the demanding OEM applications area. The devices have built-in load diagnostic functions for detecting and diagnosing misconnected outputs to help to reduce test time during the manufacturing process.
