OPA3692 OPA3692 www.ti.com SBOS228E – FEBRUARY 2002 – REVISED DECEMBER 2008 Triple, Wideband, Fixed Gain Video BUFFER AMPLIFIER With Disable FEATURES q FLEXIBLE SUPPLY RANGE: +5V to +12V Single Supply ±2.5V to ±6V Dual Supplies q INTERNALLY FIXED GAIN: +2 or ±1 q HIGH BANDWIDTH (G = +2): 225MHz q LOW SUPPLY CURRENT: 5.1mA/ch q LOW DISABLED CURRENT: 150µA/ch q HIGH OUTPUT CURRENT: 190mA q OUTPUT VOLTAGE SWING: ±4.0V q IMPROVED HIGH-FREQUENCY PINOUT DESCRIPTION The OPA3692 provides an easy-to-use, broadband fixed gain, triple buffer amplifier. Depending on the external connections, the internal resistor network may be used to provide either a fixed gain of +2 video buffer, or a gain of +1 or –1 voltage buffer. Operating on a very low 5.1mA/ch supply current, the OPA3692 offers a slew rate and output power normally associated with a much higher supply current. A new output stage architecture delivers high output current with minimal headroom and crossover distortion. This gives exceptional single-supply operation. Using a single +5V supply, the OPA3692 can deliver a 1V to 4V output swing with over 120mA drive current and > 200MHz bandwidth. This combination of features makes the OPA3692 an ideal RGB line driver or single-supply, triple Analog-toDigital Converter (ADC) input driver. The low 5.1mA/ch supply current of the OPA3692 is precisely trimmed at +25°C. This trim, along with low drift over temperature, ensures lower maximum supply current than competing products that rep...
