MICROCHIP TECHNOLOGY EXPANDS ANALOG PORTFOLIO WITH A/D CONVERTERS FEATURING FULL DIFFERENTIAL INPUTS.Microchip Technology (Nasdaq: 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 ) has introduced three upgraded, low-power analog-to-digital (A/D A/D See advance-decline line (A/D). ) converters with full differential inputs. Referred to as the 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). 330X family, these 13-bit A/D converters are ideal for remote data acquisition, transducer interface and sensing applications. Additionally, Microchip designed the low-power, low-cost devices to be easily implemented in portable and battery-powered applications. These products have a maximum sampling rate of 100 ksps and excellent linearity (+/-1 LSB (Linux Standard Base) A standard interface (ABI) for Linux from the Linux Foundation (www.linux-foundation.org). Introduced in 2001 by the Free Standards Group, which later became the Linux Foundation, applications based on the LSB standard will run properly under ) for integral non-linearity (INL) and differential non-linearity (DNL) specifications. "Microchip will continue to meet or exceed our customers' needs, proven by the introduction of the MCP330X family," said Trent Butcher, product marketing manager for the Analog and Interface Product Division at Microchip. "The A/D converters are small, fast and accurate devices that combine leading performance and value." The MCP330X devices are successive approximation 13-bit serial A/D converters with on-board sample and hold circuitry. A simple serial interface compatible with the SPI protocol is utilized for communication with the devices. The devices operate over a broad voltage range of 2.7 to 5.5 volts. Low current design enables operation with maximum standby and active currents of only 1uA and 450uA, respectively. The reference voltage can be varied from 400mV to 5V, yielding input-referred resolution between 97.6uV and 1.22mV. Microchip also offers the MXDEV Analog Evaluation System to assist designers with development of A/D circuits, including the essential tools a designer needs to create a system requiring differential inputs. Software tools provided with the system include real-time oscilloscope oscilloscope (əsĭl`əskōp'), electronic device used to produce visual displays corresponding to electrical signals. Displays of such nonelectrical phenomena as the variations of a sound's intensity can be made if the phenomena are and FFT displays. The MCP330X family is available in several small packages, including the MSOP-8 package. Because of the small size, low power and auto shutdown features, the MCP330X A/D converters are also well suited for a variety of communication and industrial applications. Pricing in 1,000-unit quantities is $1.48 each for the single MCP3301, $2.04 each for the dual MCP3302 and $2.26 each for the quad MCP3304. Samples and volume quantities are available today. The MCP3301 and MCP3304 are available in 8-pin PDIP (Plastic DIP) See DIP. , SOIC (Small Outline IC) A small-dimension, plastic, rectangular, surface mount chip package that uses gull-wing pins extending outward. See gull-wing lead, SOJ and chip package. and TSSOP TSSOP Thin Shrink Small Outline Package TSSOP Thin Scale Small Outline Package packages. The MCP3302 is available in 16-pin PDIP, SOIC and TSSOP package options. For more information, contact any Microchip sales representative or authorized worldwide distributor. |
