1N4001 vs. 1N4148: Which one is better?

  1N4148 Description The  1N4148   is a standard silicon switching signal diode. It is one of the most popular and long-lived  switching  diodes  because of its dependable  specifications  and low cost. Its name follows the  JEDEC   nomenclature. The  1N4148   is useful in  switching applications  up to about 100 MHz with a reverse-recovery time of no more than 4 ns. 1N4001 Description The  1N4001   is used in  AC adapters  for common household appliances. This  JEDEC   device number series is available in the DO-41 axial package. Diodes with similar ratings are available in SMA and MELF surface-mount packages (in other part number series).

OV7670 vs OV2640 Which one is better?

  OV7670 Description The  OV7670  CAMERACHIP TM  is a low voltage  CMOS  image sensor that provides the full functionality of a single-chip VGA camera and image processor in a small footprint package. The  OV7670  provides full-frame, sub-sampled, or windowed 8-bit images in a wide range of formats, controlled through the  Serial Camera Control Bus    (SCCB) interface. This product has an image array capable of operating at up to 30 frames per second (fps) in  VGA  with complete user control over image quality, formatting, and output data transfer. All required  image processing functions , including exposure control, gamma, white balance, color saturation, hue control, and more, are also programmable through the  SCCB  interface. In addition,  OmniVision CAMERACHIPs  use proprietary sensor technology to improve image quality by reducing or eliminating common lighting/electrical sources of image contamination, such as fixed pattern noise ( FPN ), smearing, blooming, etc., to produce a

TDA7498E vs. TPA3116D2 : Which one is better?

  TDA7498E Description The  TDA7498E   is a dual BTL class-D audio amplifier with a single  power supply  designed for home systems and active speaker applications. It comes in a 36-pin  PowerSSO   package with exposed pad up (EPU) to facilitate mounting a separate  heatsink . TPA3116D2 Description The  TPA3116D2  is a stereo efficient, digital amplifier power stage for driving speakers up to 100W / 2Ω in mono. The high efficiency of the  TPA3130D2   allows it to do 2 × 15 W without an external heat sink on a single layer  PCB . The  TPA3118D2   can even run 2 × 30 W / 8Ω without a heat sink on a dual-layer  PCB ,  If even higher power is needed the TPA3116D2 does 2 × 50 W / 4 Ωwith a small heatsink attached to its top side  PowerPAD . All three devices share the same footprint enabling a single  PCB   to be used across different power levels. The TPA3116D2 advanced oscillator/PLL circuit employs multiple switching frequency options to avoid  AM interferences ; this is achieved togeth

ESP32 vs. STM32: Which one is better?

  ESP32 Description ESP32  is a series of low-cost, low-power systems on a  chip microcontroller  with integrated  Wi-Fi  and dual-mode Bluetooth. The  ESP32   series employs either a Tensilica  Xtensa LX6   microprocessor in both dual-core and single-core variations, or an  Xtensa LX7   dual-core microprocessor, or a single-core RISC-V  microprocessor and includes built-in antenna switches, RF balun, power amplifier, low-noise receive amplifier, filters, and power management modules.  ESP32   is created and developed by  Espressif Systems , a Shanghai-based Chinese company, and is manufactured by  TSMC   using its 40 nm process. It is a successor to the  ESP8266   microcontroller. STM32 Description STM32  is a family of microcontroller ICs based on the 32-bit RISC  ARM  Cortex-M3 3F ,  Cortex-M7F ,  Cortex-M4F , Cortex-M3,  Cortex-M0+ , and Cortex-M0 cores.  STMicroelectronics   licenses the ARM Processor IP from ARM Holdings. The ARM core designs have numerous configurable options, a
