Regulator does the lot for TFT LCD
panels
The MAX8761 is a complete linear-regulator power supply for thin-film transistor liquid-crystal-display panels used in LCD monitors and LCD TVs.
Maxim Integrated Products introduces the MAX8761, a complete linear-regulator power supply for thin-film transistor (TFT) liquid-crystal-display (LCD) panels used in LCD monitors and LCD TVs Highly integrated to save cost and space, the device includes a high-performance linear regulator, a positive and a negative charge-pump regulator, built-in power-up sequence control, and a high-current operational amplifier

Speedy DAC claims dynamic superiority for comms
The MAX5195 is a 14bit 260Msample/s DAC claimed to provide the world's best dynamic performance in spurious-free dynamic range, intermodulation distortion and signal to noise ratio.
Low-power serial ADC runs up to 200Ksample/s
New from Maxim Integrated Products, the MAX1162 serial-interface 16bit A/D convertor connects directly to SPI, QSPI and Microwire devices without additional interface logic.
Additionally, the MAX8761 provides logic-controlled high-voltage switches to control the positive charge-pump output.
The MAX8761's linear regulator directly steps down the input voltage to generate the supply voltage for the source-driver ICs.
Output accuracy is 1.6% with a fast transient response.
The two built-in charge-pump regulators generate the TFT gate-on and gate-off supplies.
The high-current operational amplifier is typically used to drive the LCD backplane (VCOM) and features high-output current (150mA), fast slew rate (12V/us), and wide bandwidth (12MHz).
Its rail-to-rail inputs and output maximise flexibility.
The MAX8761 is available in a small (4 x 4mm), low-profile (0.8mm), 24-pin thin QFN package and operates over the -40 to +85C temperature range.
Prices start at $3.62 (1000-up, FOB USA).
A preassembled MAX8761 EV kit is available with recommended external components to reduce design time.
A preliminary datasheet for this product is available on the web.
