DESCRIPTION/ORDERING INFORMATION
The THS4513 is a wideband, fully differential op amp designed for 3.3 V to 5 V data-acquisition systems. It has very low noise at 2.2 nV/√Hz, and extremely low harmonic distortion of –76 dBc HD2 and –88 dBc HD3 at 70 MHz with 2 Vpp output, G = 14 dB, and 100 Ω load. Slew rate is very high at 5100 V/μs and with settling time of 5.5 ns to 1% (2 V step), it is ideal for pulsed applications. It is suitable for minimum gain of 6 dB.
To allow for dc coupling to ADCs, its unique output common-mode control circuit maintains the output common-mode voltage within 5 mV offset (typ) from the set voltage, when set within 0.5 V of mid-supply, with less than 4 mV differential offset voltage. The common-mode set point is set to mid-supply by internal circuitry, which may be over-driven from an external source.
The input and output are optimized for best performance with their common-mode voltages set to mid-supply. Along with high performance at low power supply voltage, this makes for extremely high performance single supply 5 V data acquisition systems.
The THS4513 is offered in a 16-pin ceramic flatpack package (W), and is characterized for operation over the full military temperature range from –55°C to 125°C.

This integrated circuit can be damaged by ESD. Texas Instruments 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.

(1) The absolute maximum ratings under any condition are limited by the constraints of the silicon process. 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, and functional operation of the device at these or any other conditions beyond those specified is not implied.
