DESCRIPTION
The OPA693 provides an easy to use, broadband, 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 voltage buffer.
Operating on a low 13mA supply current, the OPA693 offers
a slew rate (2500V/µs) and bandwidth (> 700MHz) 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 gives exceptional
single-supply operation. Using a single +5V supply, the
OPA693 can deliver a 2.5VPP swing with over 90mA drive
current and 500MHz bandwidth at a gain of +2. This combi-
nation of features makes the OPA693 an ideal RGB line
driver or single-supply undersampling Analog-to-Digital Con-
verter (ADC) input driver.
The OPA693’s low 13mA supply current is precisely trimmed
at 25°C. This trim, along with low drift over temperature,
ensures lower maximum supply current than competing
products that report only a room temperature nominal supply
current. System power may be further reduced by using the
optional disable control pin. Leaving this disable pin open, or
holding it HIGH, gives normal operation. This optional dis-
able allows the OPA693 to fit into existing video buffer
layouts where the disable pin is unconnected to get improved
performance with no board changes. If pulled LOW, the
OPA693 supply current drops to less than 170µA while the
output goes into a high impedance state. This feature may be
used for power savings.
The low gain stable current-feedback architecture used in the
OPA693 is particularly suitable for high full-power bandwidth
cable driving requirements. Where the additional flexibility of
an op amp is required, consider the OPA695 ultra-wideband
current feedback op amp. Where a unity gain stable voltage
feedback op amp with very high slew rate is required,
consider the OPA690.
