The OPA344 is unity gain stable, while the OPA345 is optimized for gains greater than or equal (cid:1) MicroSIZE PACKAGES to five, and has a gain-bandwidth product of 3MHz. SOT23-5 The OPA344 and OPA345 are optimized to operate on a MSOP-8 single supply from 2.5V and up to 5.5V with an input TSSOP-14 common-mode voltage range that extends 300mV (cid:1) GAIN-BANDWIDTH beyond the supplies. Quiescent current is only ≥ 250µA (max). OPA344: 1MHz, G 1 ≥ Rail-to-rail input and output make them ideal for driving OPA345: 3MHz, G 5 sampling analog-to-digital converters. They are also well suited (cid:1) SLEW RATE for general purpose and audio applications and providing I/V µ OPA344: 0.8V/ s conversion at the output of D/A converters. Single, dual and OPA345: 2V/µs quad versions have identical specs for design flexibility. (cid:1) THD + NOISE: 0.006% A variety of packages are available. All are specified for operation from –40ºC to 85ºC. A SPICE macromodel for APPLICATIONS design analysis is available for download from www.ti.com.

OPA345 series op amps are optimized for applications significantly with operating voltages or temperature are requiring higher speeds with gains of 5 or greater. shown in the Typical Performance Curves. Rail-to-rail input and output swing significantly increases dynamic range, especially in low supply applications. Figure RAIL-TO-RAIL INPUT 1 shows the input and output waveforms for the OPA344 in The input common-mode voltage range of the OPA344 and unity-gain configuration.

There is a small Input G = +1, VS = +5V transition region, typically (V+) – 1.5V to (V+) – 1.1V, in 5V which both pairs are on. This 400mV transition region can vary 300mV with process variation. Thus, the transition region (both stages on) can range from (V+) – 1.8V to (V+) v di – 1.4V on the low end, up to (V+) – 1.2V to (V+) – 0.8V on V/ 1 the high end.
