![]() This medical device takes in the real-world vital sign information of a patient and processes it into diagnostics for reliable patient assessment. It non-invasively monitors several real- world analog inputs such as blood pressure, temperature, and electrocardiograph readings. The processed outputs can then be utilized to monitor the health of the patient. Component Highlights * Operational amplifiers - precision RRIO amplifiers combine low offset and low-input bias current to enhance the performance of any precision application. * A/D converter - high speed, 10-bit or greater resolution converters allow simultaneous sampling of the I and Q channels, thus requiring only one ADC. * Voltage reference - select from several devices with tolerance of 0.5% or less to provide a precise reference for the A/D converter. * Microcontroller - highly integrated COP8® controller includes 16k masked ROM. * Buck switching regulators - 1 to 5Amp regulators are reliable and cost-effective while saving power in medical equipment. 1 Amp LMP7701MF LMP7701MFX LMP7704MT 2 Voltage Regulator LM2592HV LM2593HV LM2596 3 Reference LM4120 LM4125 LM4132 4 ADC ADC08060 ADC08100 ADC081000 5 Microcontroller LMV225 LMV226 LMV228 6 LCD Panel ![]() As display manufactures lower prices, improve performance, extend display size ranges, and adopt new, innovative form factors, they are penetrating a wider range of applications. Design your displays using Nationals expertise in portable applications and innovative packaging. Component Highlights * TFT panel module - LM2702 is a compact bias solution, with integrated Vcom and Gamma buffers, ideal for large screen LCD panels. * Panel timing controller - with LVDS technology, these controllers have programmable outputs with customized control for standard or in-house column drivers and row drivers. * Vcom reference amplifier - LM8262 is a RRIO operational amplifier specifically designed to handle the Vcom driver requirements of TFT flat panels. * Audio amplifier - Overture® amplifiers deliver audio power with high efficiency and require few external components, making them ideal for slim LCD panels (1) Integrated LVDS Rx+Tcon DS90C3201VS DS90C3202VS DS90C365AMT (2) Gamma Reference Voltage LMP7701 LMP7704 LMP8270 (3) Vcom Reference LMH6624 LMH6626 LMH6628 (4) TFT Panel Modules DS90C3201VS DS90C3202VS DS90C365AMT (5) Switching Regulator (6) LDO LP2997 LP38690 LP38691 7 Ethernet DP83847ALQA56AX DP83847ALQA56A DP83848TSQ |
