DESCRIPTION

The OPA350 series rail-to-rail CMOS operational

amplifiers are optimized for low voltage, single-supply

operation. Rail-to-rail input/output, low noise (5nV/√Hz

and high speed operation (38MHz, 22V/µs) make them

ideal for driving sampling Analog-to-Digital (A/D)

converters. They are also well suited for cell phone PA

control loops and video processing (75Ω drive capability)

as well as audio and general purpose applications. Single,

dual, and quad versions have identical specifications for

maximum design flexibility.

The OPA350 series operates on a single supply as low as

2.5V with an input common-mode voltage range that

extends 300mV below ground and 300mV above the

positive supply. Output voltage swing is to within 10mV of

the supply rails with a 10kΩ load. Dual and quad designs

feature completely independent circuitry for lowest

crosstalk and freedom from interaction.

The single (OPA350) and dual (OPA2350) come in the

miniature MSOP-8 surface mount, SO-8 surface mount,

and DIP-8 packages. The quad (OPA4350) packages are

the space-saving SSOP-16 surface mount and SO-14

surface mount. All are specified from −40°C to +85°C and

operate from −55°C to +150°C.

They are unity-gain stable and suitable for a wide range of general-purpose applications. Rail-to-rail input/output make them ideal for driving sampling A/D converters. They are also well-suited for controlling the output power in cell phones. These applications often require high speed and low noise.

"#$ %"#$ &"#$ www.ti.com SBOS099C − SEPTEMBER 2000 − REVISED JANUARY 2005 FEEDBACK CAPACITOR IMPROVES RESPONSE For optimum settling time and stability with high-impedance feedback networks, it may be necessary to add a feedback capacitor across the feedback resistor, RF, as shown in Figure 4. This capacitor compensates for the zero created by the feedback network impedance and the OPA350’s input capacitance (and any parasitic layout capacitance).
