Low Noise

The AD8319, the latest addition to Analog Devices’s family of power detectors/controllers, measures RF (radio frequency) signals over the range of 1 MHz to 10 GHz. The device supports all cellular standards (GSM, CDMA, W-CDMA and TD-SCDMA), broadband wireless standards (WiFi, WiMAX, WiBro), and prop...

Texas Instruments announced a 13-bit, 250MSPS analog-to-digital converter (ADC). The ADS5444 offers 68dB signal-to-noise ratio (SNR) and 75dB spurious-free dynamic range (SFDR) at the maximum sample rate of 250MSPS and an input frequency of 230MHz.  The ADC operates from a 5V supply, while prov...

Analog Devices introduces the AD8220 JFET-input instrumentation amplifier. The AD8220 operates on a single low-voltage power supply that draws 700 µA. The device also achieves an 80 dB common mode rejection ratio (CMRR) up to 10 kHz (G=1). With JFET (junction field effect transistor) input...

Linear Technology announces the LTC3214, a fractional charge pump, white LED driver that delivers up to 500mA of LED current. Its multi-mode architecture automatically switches between 1x, 1.5x or 2x boost modes monitoring the voltage across the LED current source and switching modes only when ILED ...

Analog Devices has extended its portfolio of general-purpose operational amplifiers (op amps) with the ADA4841 family of single and dual devices. Offering low noise and distortion and 1.1 mA of supply current.

The new op amps are achieving 2-nV/rt-Hz wideband voltage noise and 1.4-pA/rt-Hz wideba...

The ASIC manufacturer Prema Semiconductor offers the constant current driver PR4130 controlling up to three LEDs in series. Even if one or two LEDs are disconnected or short circuited, the current and the brightness remain constant, thus providing a high reliability.

The supply voltage of the PR4...
