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.
