ED_ED UPDATE: POWER AND ANALOG_ Penton Media September 28, 2009 If you want to view this on the web go to: http://enews.penton.com/enews/electronicdesign/v/887 ENGINEERING ESSENTIALS --The ABCs of ADCs By Martin Mason, Maxim Integrated Products Real-world applications require real-world connections. Generally, that means an analog signal is being digitized somewhere in the system so a microprocessor, ASIC, or FPGA can gather data and make some decision. If you're new to data converter concepts or if it's been a long time since your last analog class, this crash course on specifying analog-to-digital converters may tip the performance scales in your design's favor.

This device is a dual input MOSFET gate driver designed to optimally drive two external N-Channel MOSFETs arranged in a non-isolated synchronous buck converter topology. The input transition thresholds of the MCP14700 is ideally suited for controllers that utilize 3.0V TTL/CMOS logic. The MCP14700 has two PWM inputs to allow independent control of the external N-Channel MOSFETs. Click here for more info.

It uses a 12-V input from an array of four 3-V dc, 40-mA solar cells connected in series. At the array's maximum output of 12 V dc, its maximum output power is 12 x 40 mA = 480 mW.

Non-volatile EEPROM provides designers with the flexibility to program MCP4728 DAC input codes, configuration bits and I2C_ address bits to the EEPROM using I2C serial-interface commands. This data is held during power-off time, allowing the MCP4728 DAC's configuration and outputs to be available immediately after power-up. Click here for info.
