BLE MCUs target economical applications
Texas Instruments expanded its connectivity portfolio with a new family of wireless microcontrollers (MCU) that enable high-quality Bluetooth Low Energy (LE) at half the price of competing devices. Featuring best-in-class standby current and radio-frequency (RF) performance, the SimpleLink Bluetooth LE CC2340 family is built on the foundation of TI’s decades of wireless connectivity expertise. Pricing […]
The ups and downs of bad DACs
A digital-to-analog converter (DAC) is more prone than an analog/digital converter to signal degradation. DACs are complex devices requiring precisely matched components. For this reason, with notable exceptions, DACs are implemented as mixed-signal ICs based on MOSFET technology. Discrete component DACs are found in radar systems and high-speed test equipment including digital sampling oscilloscopes. Digital […]
The up side of under sampling
A digital signal can be derived from the original time-varying, continuous analog signal by creating a sampled sequence of quantized values. It is intuitively evident that the fidelity and resolution of this quantized signal is based upon the number of samples taken per unit of time. Harry Nyquist published an early version, later further formalized […]
High-precision radar sensor targets automotive ADAS apps
In an effort to move autonomous driving and vehicle safety forward, Texas Instruments announced an expansion of its automotive offerings that can help automakers improve how advanced driver assistance systems (ADAS) sense objects. TI’s new AWR2944 radar sensor adds to the company’s extensive portfolio of analog and embedded processing products and technologies, giving automotive engineers more […]
Measuring CMOS power use
Virtually all digital, analog and mixed-signal ICs are now done in CMOS due to the technology’s extremely low power consumption, small size and immunity to noise. Low power consumption arises from the use of a two-transistor configuration resulting in zero power consumption except during brief transitions. Interestingly, the bulk of CMOS power dissipation arises because […]
AM64x MCU-based SOM tracks industrial IoT, robotics, mission-critical apps
A new SOM powered by the AM64x processor family from Texas Instruments (TI) features best-in-class real-time and low-latency processing and targets industrial IoT and industrial machinery applications. The AM64x SOM is aimed at applications that require a combination of precise real-time processing and application processing, and comes equipped with two Cortex A53 cores for OS-level […]
24-bit wideband ADC offers data rates up to 400 kSPS
Texas Instruments introduced the smallest 24-bit wideband analog-to-digital converter (ADC) that delivers industry-leading signal-measurement precision at wider bandwidths than competing ADCs. The ADS127L11, the newest product in TI’s portfolio of precision wideband ADCs, achieves ultra-precise data acquisition in a 50% smaller package, significantly optimizing power consumption, resolution, and measurement bandwidth for a wide range of […]
Buck/boost converter boasts super-low quiescent current, targets battery powered apps
Texas Instruments introduced a new bidirectional buck/boost converter with an ultra-low quiescent current (IQ) of 60 nA – one-third the IQ of competing boost converters. The TPS61094 buck/boost converter integrates a buck mode for supercapacitor charging while providing ultra-low IQ, enabling engineers to extend battery life by as much as 20% when compared to commonly used hybrid-layer […]
