Amplifiers integrate DSP for improved power efficiency

Amplifiers integrate DSP for improved power efficiency
Designed for high-speed data acquisition systems which require a high level of accuracy, precision and power efficiency, a family of rail-to-rail amplifiers have been introduced by Analog Devices. The 100MHz ADA4805-1 (single) and ADA4805-2 (dual) amplifiers feature DPS which allows users to manage power consumption by shutting-down the amplifier between ADC samples.

Right angle AC/DC power supplies conserve board space

Right angle AC/DC power supplies conserve board space
CUI have released right angle versions of it's SIP AC/DC power supplies, which are available in 1 (PBK-1-XX-B), 3 (PBK-3-XX-B) and 5W (PBK-5-XX-B). The PBK-B family of power supplies measure as small as 35x25x13mm, making them suitable for boards with a limited space. Offered in single output voltages of 3.3, 5, 9, 12, 15 and 24VDC, the power supplies operate at AC input voltages between 85-264VAC.
