DESCRIPTION

The OPA703 and OPA704 series op amps are optimized for

applications requiring rail-to-rail input and output swing.

Single, dual, and quad versions are offered in a variety of

packages. While the quiescent current is less than 200µA per

amplifier, the OPA703 still offers excellent dynamic perfor-

mance (1MHz GBW and 0.6V/µs SR) and unity-gain stabil-

ity. The OPA704 is optimized for gains of 5 or greater and

provides 3MHz GBW and 3V/µs slew rate.

The OPA703 and OPA704 series are fully specified and

guaranteed over the supply range of ±2V to ±6V. Input

swing extends 300mV beyond the rail and the output swings

to within 40mV of the rail.

The single versions (OPA703 and OPA704) are available in

the MicroSIZE SOT23-5 and in the standard SO-8 surface-

mount, as well as the DIP-8 packages. Dual versions

(OPA2703 and OPA2704) are available in the MSOP-8,

SO-8, and DIP-8 packages. The quad OPA4703 and

OPA4704 are available in the TSSOP-14 and SO-14 pack-

ages. All are specified for operation from –40°C to +85°C.

APPLICATIONS INFORMATION Power-supply pins should be bypassed with 1000pF ceramic capacitors in parallel with 1µF tantalum capacitors. OPA703 and OPA704 series op amps can operate on 160µA quiescent current from a single (or split) supply in the range of 4V to 12V (±2V to ±6V), making them highly versatile and easy to use. The OPA703 is unity-gain stable and offers 1MHz bandwidth and 0.6V/µs slew rate. The OPA704 is optimized for gains of 5 or greater with a 3MHz bandwidth and 3V/µs slew rate.
PAGE 11
INPUT VOLTAGE Device inputs are protected by ESD diodes that will conduct if the input voltages exceed the power supplies by more than approximately 300mV. Momentary voltages greater than 300mV beyond the power supply can be tolerated if the current is limited to 10mA. This is easily accomplished with an input resistor, as shown in Figure 3. Many input signals are inherently current-limited to less than 10mA; therefore, a limiting resistor is not always required.
