National's LM49100 audio subsystem allows routing of mono voice or stereo music signals to a mono speaker driver or stereo ground-referenced headphone amplifiers (or both) through selection of pre-set modes. It consumes the industry's lowest Iq of devices in its class: < 5 mA, with all channels active. Click here for more information

Voltage Reference Selection Basics Technical Paper White Paper Voltage references are a key building block in data conversion systems, and understanding their specifications and how they contribute to error is necessary for selecting the right reference. This paper explains common reference specifications, ranks their importance, and shows how designers can use them in simple calculations to narrow their search.

LDOs Ease the Stress of Start-Up Technical Paper Application Note Typical low-dropout (LDO) linear voltage regulators do not provide a method of limiting the in-rush current during start up conditions. This paper explains how National Semiconductor's LP38851/52/53 devices, with soft-start, solve this problem and ensure that start-up into high capacitive loads is uneventful and stress free.

FlexCap Technology Simplifies LDO Design Technical Paper Application Note This paper enumerates the advantages of using National Instruments' FlexCap LDOs and demonstrates that the internal compensation used in FlexCap products can maintain regulator stability regardless of the ESR of the output capacitor.

Optimizing Power Controller Designs Through Effective Utilization of Performance Features Technical Paper White Paper When in search of power for mixed-signal electronics, engineers must satisfy performance, cost, efficiency, and space needs. This paper illustrates how the proper features can help fulfill these requirements and enhance the performance of power supply and load.

A 3 Gbps SDI Connectivity Solution Supporting Uncompressed 1080p60 Video Technical Paper White Paper This paper introduces National Semiconductor's Serial Digital Interface (SDI) Smart SerDes combined with Xilinx Spartan-3 FPGAs and the Xilinx protocol stack—a high- performance, cost-effective solution for broadcast for Standard-Definition (SD), High-Definition (HD), and Three-Gigabit SDI (3G-SDI).
