Microchip Technology Introduces 18-bit Delta-Sigma Analog-to-Digital Converter (ADC) in SOT-23 Package.Low-Power ADC (1) See A/D converter. (2) (Apple Display Connector) A peripheral connector from Apple that combines digital video display, USB and power in one cable. Provides Highest Resolution Available in SOT-23, Plus Onboard PGA (1) (Professional Graphics Adapter) An early IBM PC display standard for 3D processing with 640x480x256 resolution. It was not widely used. (2) (Programmable Gate Array) See gate array and FPGA. and Voltage Reference A voltage reference is an electronic device (circuit or component) that produces a fixed (constant) voltage irrespective of the loading on the device, power supply variation and temperature. for Smaller Designs CHANDLER, Ariz. -- Microchip Technology  Microchip Technology (NASDAQ: MCHP) is a manufacturer of microcontroller, memory and analog semiconductors, founded in 1989 when Inc. (NASDAQ NASDAQin full National Association of Securities Dealers Automated Quotations U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on : MCHP MCHP Maryland Children's Health Program MCHP Microchip Technologies (stock symbol) MCHP Micro-sized Combined Heat and Power (American Honda Motor Co. & Climate Energy, LLC) MCHP Maine Community Heritage Project ), a leading provider of microcontroller and analog semiconductors, today announced the highest resolution analog-to-digital converter (ADC) available in a SOT-23 package. The low-power, 18-bit, Delta-Sigma MCP (1) See Microsoft certification. (2) (MultiChip Package) A chip package that contains two or more chips. It is essentially a multichip module (MCM) that uses a laminated, printed-circuit-board-like substrate (MCM-L) rather than ceramic (MCM-C). 3421 ADC features an integrated voltage reference and Programmable Gain Amplifier (PGA) on-chip, which reduces the need for external components and enables a smaller overall design footprint. With its 6-pin package, low power consumption and high resolution, the new ADC is ideal for portable measurement applications in the industrial, medical, consumer and automotive markets. The MCP3421 ADC uses an I2C I2C Inter-Integrated Circuit I2C Intelligent Interface Controller I2C Intelligent Controller [TM] compatible serial interface and operates from a single power supply (2.7V to 5.5V). Microchip's low-power technology enables the device's extremely low power consumption of just 155 microAmperes at 5V continuous conversion, which helps to extend battery life in portable measurement devices. Additionally, with the device's onboard PGA, users can select the gains of x1, x2, x4 or x8 before the analog-to-digital conversion analog-to-digital or A/D conversion, the process of changing continuously varying data, such as voltage, current, or shaft rotation, into discrete digital quantities that represent the magnitude of the data takes place, enabling very high-resolution conversion of even small input signals. The integrated voltage reference and oscillator oscillator Mechanical or electronic device that produces a back-and-forth periodic motion. A pendulum is a simple mechanical oscillator that swings with a constant amplitude, requiring the addition of energy at each swing only to compensate for the energy lost because of air lessen the need for external components, resulting in simpler designs and a smaller overall design footprint. "Manufacturers are constantly pressured to provide more compact, higher-resolution products that last longer on smaller batteries," said Bryan Liddiard, vice president of marketing with Microchip's Analog and Interface Products Division. "The MCP3421 ADC meets these needs. It consumes very little power and provides 18-bit resolution, plus an integrated PGA and voltage reference -- all in a miniature, SOT-23 package." Example applications for the MCP3421 ADC include portable devices in the following markets: industrial (portable instrumentation, pressure sensors, weigh scales, handheld meters and multimeters); medical (heart rate monitors and blood glucose blood glucose Diabetology The principal sugar produced by the body from food–especially carbohydrates, but also from proteins and fats; glucose is the body's major source of energy, is transported to cells via the circulation and used by cells in the presence meters); consumer (weigh scales and handheld meters); and automotive (sensor interfaces and fuel gauges).
