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 –75 dBc HD2 and –86 dBc HD3 at 70 MHz with 2-VPP output, G = 0 dB, and 200-
load. Slew rate is very high at 5100 V/μs and with settling time of 2.9 ns to 1% (2-V step), it is ideal for pulsed applications. It is designed for a minimum gain of 0 dB.
To allow for dc-coupling to analog-to-digital converters (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 midsupply, with less than 4-mV differential offset voltage. The common-mode set point is set to midsupply by internal circuitry, which may be overdriven from an external source.
The input and output are optimized for best performance with their common-mode voltages set to midsupply. Along with high performance at low power-supply voltage, this design makes it ideal for extremely high-performance, single-supply 5-V data acquisition systems.
The THS4513 is offered in a quad, leadless QFN-16 package (RGT), and is characterized for operation over the full industrial temperature range from –40°C to +85°C.
