The PCM1864 circular microphone board (CMB) is a low-cost easy-to-use reference design for applications that require clear-spoken audio, such as voice triggering and speech recognition. This TI Design uses a microphone array to capture a voice signal, and converts it to a digital stream that can be used by DSP systems to extract clear audio from noisy environments.
Active Balance chipset used in large lithium-ion batteries provides monitoring, balancing and communication functions. With precise and reliable active balancing, Active Balance BMS enables bidirectional power transfer within each cell. Each EM1401EVM can manage 6 to 14 cells (up to 60V) in Li-ion battery applications. EM1401EVM modules can be stacked up to 1300V. The system provides fast cell balancing, diagnostic functions and modules for controller communication. An independent protection circuit is also provided.
Power-over-Ethernet (PoE) technology enables power-sourcing equipment (PSE, a switch/router or midspan system) to deliver up to 15W of power to IEEE® 802.3af-compliant powered devices like IP phones and wireless LAN access points. This application note describes how to design a single-port PSE system to meet the IEEE 802.3af signature, classification, and power-management requirements. The single-port PSE in this example is designed using the MAX5922A IC.

New Analog/Analog Isolator Using Isolated Σ-Δ Modulator, Isolated DC/DC Converter and Active Filter
This LED driver reference design drives a 700mA constant current to a single string of LEDs with forward voltages up to 60V. The design allows PWM dimming based on supply chopping. The input power supply is chopped on and off at 300Hz to 1kHz frequency to achieve LED brightness control. The driver uses a fixed-frequency boost converter, controlled by the MAX16834 LED driver. This unique reference design limits the input inrush current to negligible levels without compromising either the input or output filtering. Design schematics and test results are provided.
LPS25H adapter board for standard DIL24 socket
This reference design is a power supply optimized specifically for powering eight 16-channel receive AFE ICs in ultrasound imaging systems. This design uses a single-chip DC/DC converter + LDO combo regulator to set each LDO input just above the dropout voltage while fully utilizing the LDO PSRR, thereby reducing parts count while maximizing efficiency. In addition, ultra-low noise LDOs help achieve the highest possible analog-to-digital conversion resolution, resulting in higher image quality. The design's ability to synchronize the switching frequency with the master clock frequency and the system clock frequency allows system designers to apply simple filtering techniques to eliminate power switching noise on ground loops or use spread spectrum clocking to reduce EMI. Additionally, the design implements an electronic fuse device, providing a simple and flexible method of overcurrent protection.
The MAX17509 integrates two 3A internal switch step-down regulators with programmable features. The device can be configured as two single-phase, independent, 3A power supplies or as one dual-phase, single-output 6A power supply. It operates from a 4.5V to 16V input and generates independently adjustable output voltage in the ranges of 0.904V to 3.782V and 4.756V to 5.048V, with ±2% system accuracy. This device provides maximum flexibility to the end user by allowing one to choose multiple programmable options by connecting resistors to the configuration pins.
The SimpleLink™ Multi-Standard CC2650 Remote Control Reference Design is an all-in-one solution for the development of voice-based Bluetooth® Low Energy, ZigBee® RF4CE™ or multi-standard remote control. This reference design shows the recommended decoupling and RF layout for optimal RF performance. This design uses discrete components for the balun and filter, as well as an inverted F-shaped PCB antenna to provide good performance at low cost.
