A/D convertor measures smaller signals faster
Sigma-delta ADC achieves greater than true 16bit noise-free resolution up to 2.4kHz across all input voltages from 40mV to 5V.
SAR convertor claims record speed and accuracy
A/D convertor achieves a new level of 16bit data capture performance, with best-in-class 15bit ENOB and 10Msample/s throughput.
Power design engineers with no prior programming experience can use the GUI to monitor and quickly adjust power functions such as frequency, timing, voltage settings and protection limits.
In end-system implementations, the ADP1043 helps system integrators optimise power supply energy efficiency, while reducing design cycle time and enabling intelligent power management systems.
The ADP1043 uses an application-specific, on-chip digital control engine that works in concert with the GUI and an industry-standard I2C interface.

Combined two-chip solution can reduce the active component count by 60% within a radio design, providing considerable board area and bill of material savings.
The new power control and management device incorporates a highly integrated circuit design that significantly reduces component count compared with competing analogue and digital power controllers.
"Analog Devices defined the GUI and the architecture of the ADP1043 to help today's power design engineers develop intelligent, adaptable power management solutions that accurately report parametric information in real time, without requiring the designer to program in C++ or other languages", says Peter Henry, Vice President and General Manager, Power Management Products, Analog Devices.
"With the ADP1043, ADI addresses the requirements of high-reliability power supply systems, where digital power introduces significant control and monitoring benefits to provide a competitive advantage in server, storage, and communications infrastructure applications".
The single-chip ADP1043 integrates on-chip technology for isolated power conversion, housekeeping, and monitoring that enables the practical implementation of more energy efficient power supply designs.
The ADP1043 controller's features include: seven-output PWM; onboard memory for program and data storage; the choice of traditional analogue or open-standard digital current share schemes for parallel power supply operation; MOSFET ORing control for redundant power supply operation, and differential voltage sensing and trimming - all of which can be programmed and adjusted via the I2C interface.
The ADP1043 will be available for general sampling in May 2008 and will be available in production quantities in August 2008.
The ADP1043 is priced at US $4.50 per unit in 1000-piece quantities and comes in a 32-pin LFCSP (5 x 5mm) package.
