RAD-TOLERANT CLASS V, WIDEBAND, FULLY DIFFERENTIAL AMPLIFIER

• Fully Differential Architecture

• Centered Input Common-Mode Range

The THS4513 is a wideband, fully differential op amp

designed for 3.3 V to 5 V data-acquisition systems. It

• Minimum Gain of 2V/V (6 dB)

has very low noise at 2.2 nV/

√Hz, and extremely low

• Bandwidth: 1100 MHz (Gain = 6 dB)

• Slew Rate: 5100 V/μs

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

• 1% Settling Time: 5.5 ns

settling time of 5.5 ns to 1% (2 V step), it is ideal for
