Intersil Announces New Multi-Channel Buffers with Integrated VCOM Amplifier for TFT-LCD Monitors
-- New 8, 10 and 12 gamma buffers reduce component count, costs and space
IRVINE, CA, October 29, 2002 Intersil Corporation (NASDAQ: ISIL), a world leader in the design and manufacture of high performance analog and wireless networking solutions, today introduced three new multi-channel buffer products with integrated common voltage (VCOM) amplifiers. Integrating 8 (EL5224C), 10 (EL5324C) and 12 (EL5424C) buffers for gamma voltage buffering with the high power VCOM amplifier enables thin-film transistor liquid crystal display (TFT-LCD) monitor manufacturers to reduce component count over using separate VCOM op-amps. This results in a reduction in manufacturing costs and saves precious board space.
Intersils new multi-channel buffers allow our customers to integrate a single product in applications which have traditionally used up to four ICs. said Michael Jennings, director of marketing for Intersils Elantec Video Products. As a leader in buffer and VCOM products for the display industry, Intersil continues to drive the integration curve for our customers.
EL5x24C Technical Description
The EL5224C, EL5324C and EL5424C integrate 8, 10 and 12 buffers respectively with a single high-power VCOM amplifier. In TFT-LCD displays, the gamma buffers are used to buffer reference voltages set up using a resistor string into the column drivers. These voltages represent the gamma response of the LCD panel. The VCOM amplifier is used to buffer a voltage that drives the backplane of the LCD.
The VCOM amplifier is specified at 100mA output current. It is designed to drive capacitive loads and features excellent load regulation. Each gamma buffer has rail-to-rail input and output capability and is specified at 30 mA output current per channel. The EL5224C, EL5324C and EL5424C operate with supplies from 5 V to 18 V and consume just 6.5 mA, 7.8 mA and 8.8 mA respectively.
The EL5x24C extends Intersils offering of current gamma buffers and VCOM amplifiers. Existing products include the EL5220C and EL5420C VCOM amplifiers and the EL5x23C family of 4, 8, 10 and 12 channel buffers.
Availability and Pricing
The EL5224C is available in both 24-pin heatsink thin-shrink small outline package (HTSSOP) and 24-pin leadless plastic package (LPP) packages, priced at $1.60 in 10,000-unit quantities. The EL5324C is $1.76 in 10,000-unit quantities and is available in the 28-pin HTSSOP and 32-pin LPP packages. Also in the 32-pin LPP package, the EL5424C is priced at $1.90 in 10,000-unit quantities. All parts are available now in production quantities.
