• 650MHz BANDWIDTH (G = +2)
The OPA3693 provides an easy to use, broadband,
triple, fixed-gain buffer amplifier. Depending on the
• FIXED GAIN OF ± 1 or +2
external connections, the internal resistor network
• OUTPUT VOLTAGE SWING: ± 4.1V
may be used to provide either a fixed gain of +2
• ULTRA-HIGH SLEW RATE: 2500V/ µ s
video buffer or a gain of +1 or – 1 voltage buffer. The
• 3RD-ORDER INTERCEPT: > 40dBm OPA3693 offers a slew rate (2500V/ µ s) and
bandwidth (> 800MHz) normally associated with a
(f < 50MHz)
much higher supply current. A new output stage
• LOW POWER: 130mW/channel
architecture delivers high output current with a
• LOW DISABLED POWER: 0.4mW/channel
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.
• MULTIPLE LINE VIDEO DISTRIBUTION
AMPLIFIER (DA)
The OPA3693 13mA/channel supply current is
• PORTABLE INSTRUMENTS
precisely trimmed at +25 ° C. This trim, along with a
• BROADBAND VIDEO LINE DRIVERS low temperature drift, gives lower system power over
temperature. System power can be further reduced
• ADC BUFFERS
using the optional disable control pin. Leaving this pin
• HIGH-FREQUENCY ACTIVE FILTERS
open, or holding it HIGH, gives normal operation. If
pulled LOW, the OPA3693 supply current drops to
less than 130 µ A/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.
