In addition to small size, this part features wide output swing, very low quiescent current, and low bias current. Other features include unity gain stability and the best speed power ratio available. Power supplies in the range of 2.2V to 36V (±1.1V to ±18V) can be used. Each channel uses completely independent circuitry for lowest crosstalk and freedom from interaction, even when overloaded. In addition, the amplifier is free from output inversion when the inputs are driven to the rail. The OPA4243EA is supplied in the miniature TSSOP-14 surface mount package. Specifications apply from –40°C to +85°C. However, as the extensive typical performance curves indicate, the OPA4243 can be used over the full –55°C to +125°C range. A SPICE macromodel is available for design analysis.

(3) Short-circuit to ground, one amplifier per package. ELECTROSTATIC DISCHARGE SENSITIVITY This integrated circuit can be damaged by ESD. 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.

The power supply pins should be bypassed with 0.01µF ceramic capacitors. OPERATING VOLTAGE The OPA4243 can operate from single supply (2.2V to 36V) or dual supplies (±1.1V to ±18V) with excellent performance. Unlike most op amps which are specified at only one supply voltage, the OPA4243 is specified for real world applications; a single set of specifications applies throughout the 2.6V to 36V supply range. This allows the designer to have the same assured performance at any supply voltage within this range. In addition, many key parameters are guaranteed over the specified temperature range, –40°C to +85°C. Most behaviors remain unchanged throughout the full operating voltage range. Parameters, which vary significantly with operating voltage or temperature, are shown in the typical performance curves. PRINTED CIRCUIT BOARD LAYOUT See Burr-Brown Application Note AB-132 for specific PC board layout recommendations. INPUT PROTECTION Rail-to-rail input signals will not cause damage or invert the output of the OPA4243. To protect against ESD and excessive input voltage (beyond the supply rails) the OPA4243 includes diodes from the input terminals to the power supply rails. Normally, these diodes are reversed biased and have negligible effect on circuit operation. However, if the input voltage is allowed to exceed the supply voltages by enough to forward bias these diodes (generally, 0.3V to 0.6V) excessive input current could flow. If this condition could occur (for example, if an input signal is applied when the op amp supply voltage is zero), care should be taken to limit the input current to less than 10mA to avoid damage. An input signal beyond the supplies, with power applied, can cause an unexpected output inversion. ® 7 OPA4243
