The DS90C387/DS90CF388 is a transmitter/receiver pair that supports dual pixel data transmission between the host and flat panel display up to QXGA resolutions. It offers multiple modes and features, including dual pixel data transmission, single pixel data transmission, and interoperability with FPD-Link devices.

The LM2750 is a regulated switched-capacitor doubler that produces a low-noise output voltage. The 5.0V output voltage option (LM2750-5.0) can supply up to 120mA of output current over a 2.9V to 5.6V input range, as well as up to 40mA of output current when the input voltage is as low as 2.7V. An adjustable output voltage option with similar output current capabilities is also available (LM2750-ADJ). The LM2750 has been placed in National’s 10-pin LLP, a package with excellent thermal properties that keeps the part from overheating under almost all rated operating conditions A perfect fit for space-constrained, battery-powered applications, the LM2750 requires only 3 external components: one input capacitor, one output capacitor, and one flying capacitor. Small, inexpensive ceramic capacitors are recommended for use. These capacitors, in conjunction with the 1.7MHz fixed switching frequency of the LM2750, yield low output voltage ripple, beneficial for systems requiring a low-noise supply. Pre-regulation minimizes input current ripple, reducing input noise to negligible levels. A tightly controlled soft-start feature limits inrush currents during part activation. Shutdown completely disconnects the load from the input. Output current limiting and thermal shutdown circuitry protect both the LM2750 and connected devices in the event of output shorts or excessive current loads.

LM3886 is a high-performance audio power amplifier from TI that delivers 68W of continuous average power and 0.1% THD+N, meeting the needs of various audio applications.

LM3881 Power Sequencer offers the easiest method to control power up and power down of multiple power supplies (switching or linear regulators).

LM380 is a 2.5W audio amplifier. The input signal can be ground referenced, the output voltage is automatically centered at one-half the supply voltage. There is short circuit protection and the output power range is wide. It can be used in various audio systems.

The LMV1089 is a dual input, Clarisound Far Field Noise Suppression Microphone Amplifier with Automatic Calibration Capability

LM27961 is a charge-pump-based white-LED driver that is ideal for mobile phone display backlighting. It can drive 4 LEDs for a main phone display backlight and 3 LEDs for a sub-display backlight. The driver provides excellent current and brightness matching in all LEDs. The LED driver current sources are split into two independently controlled groups. The primary group (Group A) can be used to backlight a main phone display with up to 4 LEDs, with low-side current drivers accommodating common-anode-type LEDs. The second group (Group B) can backlight a secondary display with up to 3 LEDs, with high-side current drivers accommodating common-cathode-type LEDs. Both Group A and Group B can also drive standard two-terminal LEDs, and provide other general lighting functions (keypad lighting, fun lighting, etc). The brightness of the two LED groups can be adjusted independently with external resistors. The LM27961 works off an extended Li-Ion input voltage range (2.7V to 5.5V), achieving voltage boost with a high-efficiency 3/2x-gain charge pump. The LM27961 is available in National’s chip-scale 18-bump micro SMD package.

The DS90CP04 1.5 Gbps 4x4 LVDS Crosspoint Switch is a digital cross-point switch produced by National Semiconductor Corporation. It uses Low Voltage Differential Swing (LVDS) technology for low power, high speed and low noise.
