It also integrates nonvolatile multiple-time programmable memory which supports up to 100 write operations of gamma and VCOM values to chip. On-chip, 10-bit DAC contains low-pass filter that reduces horizontal line frequency noise by 50 dB. Unit is available in 5 x 5 mm, 28-pin TQFN-EP package and is specified over -40 to +85°C temperature range.
Original Press Release:
Highly Integrated, 10-Bit Programmable Gamma and VCOM Reference System with Nonvolatile Memory
10-bit, 16-channel programmable gamma reference system provides MTP memory.
SUNNYVALE, CA - June 22, 2009 - Maxim Integrated Products (NASDAQ: MXIM) 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°C to +85°C extended temperature range. Prices start at $1.80 (1000-up, FOB USA).
