DESCRIPTION

•

FLEXIBLE SUPPLY RANGE:

The OPA690 represents a major step forward in

+5V to +12V Single Supply

unity-gain stable, voltage-feedback op amps. A new

±2.5V to ±5V Dual Supply

internal architecture provides slew rate and full-power

bandwidth

previously

found

only

in

wideband,

•

UNITY-GAIN STABLE: 500MHz (G = 1)

current-feedback op amps. A new output stage

•

HIGH OUTPUT CURRENT: 190mA

architecture delivers high currents with a minimal

•

OUTPUT VOLTAGE SWING: ±4.0V

headroom

requirement.

These

combine

to

give

exceptional single-supply operation. Using a single

•

HIGH SLEW RATE: 1800V/µs

+5V supply, the OPA690 can deliver a 1V to 4V

•

LOW SUPPLY CURRENT: 5.5mA

output swing with over 150mA drive current and

•

LOW DISABLE CURRENT: 100µA

150MHz bandwidth. This combination of features

makes the OPA690 an ideal RGB line driver or

•

WIDEBAND +5V OPERATION: 220MHz (G = 2)

single-supply Analog-to-Digital Converter (ADC) input

driver.

APPLICATIONS

•

VIDEO LINE DRIVING

The low 5.5mA supply current of the OPA690 is

precisely trimmed at +25°C. This trim, along with low

•

xDSL LINE DRIVER/RECEIVER

temperature

drift,

gives

lower

maximum

supply

•

current than competing products. System power may

•

ADC BUFFERS

be reduced further using the optional disable control

•

PORTABLE INSTRUMENTS

pin. Leaving this disable pin open, or holding it HIGH,

will operate the OPA690 normally. If pulled LOW, the

•

TRANSIMPEDANCE AMPLIFIERS

OPA690 supply current drops to less than 100mA

•

ACTIVE FILTERS

while the output goes to a high-impedance state. This

feature may be used for power savings.
