New Analog/Analog Isolator Using Isolated Σ-Δ Modulator, Isolated DC/DC Converter and Active Filter
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.
This reference design demonstrates how to implement a capacitive touch button, commonly used as a setting button in a proximity switch, in an ultra-small 3.5mm wide PCB based on TI's CapTIvate™ technology. When combined with the highly integrated IO-Link PHY, flexible PNP or NPN outputs are possible. The SIO stage provides reverse polarity, ESD, EFT and surge protection, making the design compliant with IEC 61000-4 standards. Hall sensors with analog output signals enable flexible use by teaching the distance to magnetic objects via a capacitive teach button. This analog signal is captured by the MCU's integrated ADC.
KITFS85FRDMEVM is a development board for the 24V truck market. It is used to maintain Vbat current up to 60V and can support all transient pulses.
The MAXREFDES1153 is a monitoring solution for genuine lithium-ion (Li+) battery packs with 2 to 15 cells connected in series. This reference design provides an accurate state of charge (SOC) in milliamp-hours (mAh) or percentage (%), as well as precision measurements of current, voltage, and temperature for multicell battery packs.
Pasadena (MAXREFDES31#) is a highly efficient, flyback, 3.3V and 5V Class 4 powered device (PD) with a 40V to 57V auxiliary input. The design features the MAX5969B as the controller. The MAX5974A controls current-mode PWM converters and provides frequency foldback for both the auxiliary input and power-over-Ethernet (PoE) applications. The design is a high-performance, compact, IEEE® 802.3af/at compliant, cost-efficient solution for a PD with power level up to Class 4. The design can also support the auxiliary-input to provide approximately 21W output power.
Analog input and output modules are standard components of programmable logic controllers (PLCs) or distributed control systems (DCS). In these modules, the increasing number of channels per module and the thinner and thinner modules present design challenges for isolated power supplies. All designers facing these challenges will benefit from the TIDA-00237 as its total design size is less than 2.54x2.54mm and its height is less than 5mm. It uses a flyback approach, which means no optocoupler feedback is required, and has a wide input voltage range of 12V-36V. This design provides +/-15V and 5V isolated low-noise outputs, making it ideal for driving data converters or analog front ends.
The NXQ1TXH5DB1355 is a debugging board that can be used during the development of applications with the NXQ1TXH5 one chip wireless charging IC
This reference design demonstrates how to use the IWR6843, a single-chip millimeter wave radar sensor from TI with an integrated DSP, to implement indoor and outdoor people counting applications while enabling sub-1GHz wireless communications. This reference design uses the MMWAVEICBOOST and IWR6843ISK evaluation modules (EVMs) and the LAUNCHXL-CC1352R1 wireless MCU LaunchPadTM. The solution is capable of locating people at distances up to 6 meters (close configuration) and 14 meters (long range configuration).
This reference design is a complete application design for an automotive LED application. It utilizes the MAX15005 current-mode controller to boost a standard lead-acid car battery to 21V for driving a string of automotive LEDs.
Simple easy to use high side current sense amps protects power supplies as a result of irregular supply voltage caused by short-circuit conditions.
