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.
