Description

The OPA3693 provides an easy to use, broadband, triple, fixed-gain 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. The OPA3693 offers a slew rate (2500V/µs) and bandwidth(> 800MHz) normally associated with a much higher supply current. A new output stage architecture delivers high output current with a minimal headroom and crossover distortion. This combination of features makes the OPA3693 an ideal RGB line driver or single-supply undersampling analog-to-digital converter (ADC) input driver. The OPA3693 13mA/channel supply current is precisely trimmed at +25°C. This trim, along with a low temperature drift, gives lower system power over temperature. System power can be further reduced using the optional disable control pin. Leaving this pin open, or holding it HIGH, gives normal operation. If pulled LOW, the OPA3693 supply current drops to less than 130µA/channel. This power-saving feature, along with exceptional single +5V operation, make the OPA3693 ideal for portable applications. The OPA3693 is available in an SSOP-16 package. The OPA3693 provides an easy to use, broadband, triple, fixed-gain buffer amplifier.
