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/ms) 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 130mA/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.
