They are optimized to operate on a single supply as low as 2.5V with an input commonmode voltage range that extends 300mV beyond the supplies. Rail-to-rail input/output and high-speed operation make them ideal for driving sampling Analog-to-Digital Converters (ADC). They are also well suited for generalpurpose and audio applications and providing I/V conversion at the output of Digital-to-Analog Converters (DAC). Single, dual, and quad versions have identical specs for design flexibility. The OPA342 series offers excellent dynamic response with a quiescent current of only 250µA max. Dual and quad designs feature completely independent circuitry for lowest crosstalk and freedom from interaction. ● ● ● ● ● ● APPLICATIONS ● ● ● ● ● ● ● ● COMMUNICATIONS PCMCIA CARDS DATA ACQUISITION PROCESS CONTROL AUDIO PROCESSING ACTIVE FILTERS TEST EQUIPMENT CONSUMER ELECTRONICS PACKAGE SINGLE OPA342 SOT23-5 ✔ QUAD OPA4342 ✔ MSOP-8 SO-8 DUAL OPA2342 ✔ ✔ TSSOP-14 ✔ SO-14 ✔ DIP-14 ✔ SPICE MODEL available at www.burr-brown.com.

Burr-Brown recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. NOTES: (1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may degrade device reliability. These are stress ratings only. Functional operation of the device at these conditions, or beyond the specified operating conditions, is not implied. (2) Input terminals are diode-clamped to the power supply rails. Input signals that can swing more than 0.5V beyond the supply rails should be current-limited to 10mA or less. (3) Short-circuit to ground, one amplifier per package.
