SBOS353 – DECEMBER 2006

Triple, Ultra-Wideband, Fixed-Gain,

VIDEO BUFFER with Disable

• 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/µs

video buffer or a gain of +1 or –1 voltage buffer. The

• 3RD-ORDER INTERCEPT: > 40dBm

OPA3693

offers

a

slew

rate

(2500V/

µs) 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

• HIGH-FREQUENCY ACTIVE FILTERS

pin open, or holding it HIGH, gives normal operation.

If pulled LOW, the OPA3693 supply current drops to

less than 130

µA/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.
