Beschreibung :

The AD9772A is a single-supply, oversampling, 14-bit digital to-analog converter (DAC) optimized for baseband or IF waveform reconstruction applications requiring exceptional dynamic range. Manufactured on an advanced CMOS process, it integrates a complete, low distortion 14-bit DAC with a 2× digital interpolation filter and clock multiplier. The on-chip PLL clock multiplier provides all the necessary clocks for the digital filter and the 14-bit DAC. A flexible differential clock input
allows for a single-ended or differential clock driver for optimum jitter performance.

Single 3.1 V to 3.5 V supply
14-bit DAC resolution and input data width
160 MSPS input data rate
67.5 MHz reconstruction pass band @ 160 MSPS
74 dBc SFDR @ 25 MHz

BP2831A Datenblatt PDF

Teilenummer : BP2831A

Function : Non-isolated Buck Offline LED Driver

Hersteller : Unspecified

Pinout :

BP2831A datenblatt

Beschreibung :

The BP2831A is a high precision buck constant current LED driver. The device operates in critical conduction mode and is suitable for 85Vac~265Vac universal input offline LED lighting.

The BP2831A  integrates a 500V power MOSFET. With patent pending MOSFET driving technique, the operating current of the IC is very low . So it doesn’t need the auxiliary winding for supplying the chip. It can achieve excellent constant current performance with very few external components, so the system cost and size are minimized.
