Maxim : Gamma correction IC has 16 programmable outputs

Maxim Integrated Products introduces the MAX9669, a low-cost, 16-channel, gamma-correction reference system with integrated nonvolatile (NV) memory. Offering 16 programmable gamma-correction outputs and one voltage reference for VCOM adjustment, this highly integrated device minimizes solution cost in TFT-LCDs. The MAX9669 can eliminate multiple discrete components including a digital variable resistor, VCOM amplifier, gamma buffers, resistor strings, and a high-voltage linear regulator. The high-voltage linear regulator is not needed because the on-chip, 10-bit DAC contains a lowpass filter that reduces the horizontal line frequency noise by 50dB. Additionally, the MAX9669 has nonvolatile, multiple-time programmable (MTP) memory that supports up to 100 write operations of gamma and VCOM values to the chip, thus eliminating the need for external EEPROM. A low-cost gamma-correction solution, the MAX9669 is ideal for LCD-based TVs, notebook PCs, and monitors.

The MAX9669 is available in a 5mm x 5mm, 28-pin TQFN-EP package with excellent heat dissipation. This device is fully specified over the -40 degrees Celsius to +85 degrees Celsius extended temperature range. Prices start at $1.80 (1000-up, FOB USA).

Maxim Integrated Products is a publicly traded company that designs, manufactures, and sells high-performance semiconductor products. The Company reported revenue in excess of $2 billion for fiscal 2008.
