provides direct interfacing with low voltage microcontrollers down to 1.62V, and an ON pin enables the LTM2887 to be shutdown and use less than 10μA. The LTM2887 provides uninterrupted communications for common mode transients greater than 30kV/μs and rugged ±10kV ESD (HBM) protection across the isolation barrier. The LTM2887 is available in two communications interface versions. The LTM2887-I is I²C compliant at up to 400kHz with bidirectional serial data (SDA) plus clock (SCL) and three additional isolated CMOS logic signals that operate at up to 10MHz. The LTM2887-S is SPI-compliant and offers a total of six CMOS digital isolator communication channels. All channels operate at up to 10MHz and include three forward direction signals (CS, SCK and SDI) and three reverse direction signals (SDO, DO1 and DO2). When configured for SPI communications, the maximum clock rate is 8MHz for unidirectional communication or 4MHz for round-trip bidirectional operation.

Reduces electromagnetic interference (EMI): Switching above the AM band eliminates the need for complex avoidance schemes and eases electromagnetic compatibility (EMC) designs while enabling the system to meet Comité International Spécial des Perturbations Radioélectriques (CISPR) 25 Class 5 EMC requirements. Supports low impedance: Maintains stable audio playback while driving low impedance loads of 2 ohms. Advanced AC load diagnostics and line driver mode: The TAS6424-Q1 provides detailed on-chip phase and impedance measurements that designers can use to configure the device with various outputs, such as woofer, tweeter and line-level connections. Enhanced audio quality: Improves distortion, power-supply rejection and dynamic response with high-frequency switching. Lower noise: An integrated digital-to-analog converter helps deliver a low system output noise of 42 uVrms for automotive designs like external amplifiers and head units. Better thermal performance: Reduces power dissipation by as much as 60 percent compared to Class-AB amplifiers, greatly reducing the need for fans or large heat sinks. Tools and support to jump-start design ThePurePath™Consolegraphical user interface isavailable to help designers easily configure the TAS6424-Q1. To simulate and optimize the device, designers can download an IBISmodel or request a TAS6424-Q1 evaluation module. Package, availability and pricing The TAS6424-Q1 is available now in a PowerPAD™ thermally enhanced shrink small-outline package (HSSOP) from the TI store and authorized distributors. Pricing is US$5.97 in 1,000-unit quantities.

Industry’s first 2.1-MHz Class-D amplifier transforms automotive audio design Texas Instruments (TI) (NASDAQ:TXN) today introduced the first 2.1-MHz Class-D audio amplifier specifically designed for automotive applications. Supporting high- resolution 96-kHz digital input, the compact TAS6424-Q1 enables high-fidelity audio with low distortion in automotive infotainment applications. For more information, visit www. ti.com/tas6424q1-pr-eu. tas6424-q1_chip_5dec16 The TAS6424-Q1 enables the use of smaller external filters and eliminates up to 18 external components to reduce system size and cost compared to existing Class-D solutions. With maximum output power of 75 W per channel, the device features the industry’s highest switching rate and is the only audio amplifier that switches above the AM band.
