DESCRIPTION
The OPA3690 represents a major step forward in unity-gain
stable, voltage-feedback op amps. A new internal architec-
ture provides slew rate and full power bandwidth previously
found only in wideband current-feedback op amps. A new
output stage architecture delivers high currents with a mini-
mal headroom requirement. These give exceptional single-
supply operation. Using a single +5V supply, the OPA3690
can deliver a 1V to 4V output swing with over 100mA drive
current and 150MHz bandwidth. This combination of fea-
tures makes the OPA3690 an ideal RGB line driver or single-
supply Analog-to-Digital Converter (ADC) input driver.
The OPA3690鈥檚 low 5.5mA/ch supply current is precisely
trimmed at 25擄C. This trim, along with low temperature drift,
ensures lower maximum supply current than competing
products. System power may be reduced further using the
optional disable control pin. Leaving this disable pin open,
or holding it HIGH, will operate the OPA3690 normal. If
pulled LOW, the OPA3690 supply current drops to less than
100碌A(chǔ)/ch while the output goes into a high impedance
state. This feature may be used for power savings.
