DESCRIPTION
The OPA341 series rail-to-rail CMOS operational amplifiers are designed for low-cost, miniature applications. They are optimized for low-voltage, single-supply operation. Rail-to-rail
input and output and high-speed operation make them ideal for driving sampling Analog-to-Digital (A/D) converters.
The power-saving shutdown feature makes the OPA341 ideal for portable low-power applications. The OPA341 series is also well suited for general-purpose and audio applications as well as providing I/V conversion at the output of Digital-to-Analog (D/A) converters. Single and dual versions have identical specifications for design flexibility.
The OPA341 series operate on a single supply as low as 2.5V, and input common-mode voltage range extends 300mV beyond the supply rails. Output voltage swings to within 1mV of the supply rails with a 100kΩ load. The OPA341 series offers excellent dynamic response (BW = 5.5MHz, SR = 6V/μs) with a quiescent current of only 750μA. The dual design features completely independent circuitry for lowest crosstalk and freedom from interaction.
The single (OPA341) packages are the tiny SOT23-6 surface mount and SO-8 surface mount. The dual (OPA2341) comes in the miniature MSOP-10 surface mount. All are specified from –55°C to +125°C and operate from –55°C to +150°C. The OPA343 provides similar performance without shutdown capability.

TLV320AIC33 - LOW POWER STEREO AUDIO CODEC FOR PORTABLE AUDIO/TELEPHONY

DESCRIPTION
The OPA2680 represents a major step forward in unity gain stable, voltage feedback op amps.
A new internal architecture 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 minimal headroom requirement.
These combine to give exceptional single supply operation.
Using a single +5V supply, the OPA2680 can deliver a 1V to 4V output swing with over 100mA drive current and 150MHz bandwidth.
This combination of features makes the OPA2680 an ideal RGB line driver or single supply ADC input driver.
The OPA2680’s low 6.4mA/ch. supply current is precisely trimmed at 25°C.
This trim, along with low temperature drift, guarantees lower maximum supply current
than competing products.
System power may be reduced further using the optional disable control pin (SO-14 package only).
Leaving this disable pin open, or holding it high, will operate the OPA2680N normally.
If pulled low, the OPA2680N supply current drops to less than 600mA while the output goes into a high impedance state.

FEATURES
*WIDEBAND +5V OPERATION: 220MHz (G = 2)
*HIGH OUTPUT CURRENT: 150mA
*OUTPUT VOLTAGE SWING: ±4.0V
*HIGH SLEW RATE: 1800V/ms
*LOW SUPPLY CURRENT: 6.4mA/Ch.
*LOW DISABLED CURRENT: 300mA/Ch.
*ENABLE/DISABLE TIME: 25ns/100ns

APPLICATIONS
*VIDEO LINE DRIVING
*xDS*LINE DRIVER/RECEIVER
*HIGH SPEED IMAGING CHANNELS
*ADC BUFFERS
*PORTABLE INSTRUMENTS
*TRANSIMPEDANCE AMPLIFIERS
*ACTIVE FILTERS
