WIDEBAND, LOW NOISE, LOW DISTORTION FULLY DIFFERENTIAL AMPLIFIER

•

Fully Differential Architecture

The THS4513 is a wideband, fully differential op amp

designed for 3.3–5 V data acquisition systems. It has

•

Centered Input Common-mode Range

very low noise at 2.2 nV/

√Hz, and extremely low

•

Minimum Gain of 1V/V (0 dB)

•

Bandwidth: 1600 MHz

at 70 MHz with 2-Vpp output, G = 0 dB, and 200-

•

Slew Rate: 5100 V/

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

•

1% Settling Time: 2.9 ns

pulsed applications. It is designed for minimum gain

•

of 0 dB.

•

To allow for dc coupling to ADCs, its unique output

common-mode voltage within 5 mV offset (typ) from

the set voltage, when set within 0.5 V of mid-supply,

Input Voltage Noise: 2.2 nV/

√Hz (f >10 MHz)

with less than 4 mV differential offset voltage. The

internal circuitry, which may be over-driven from an

external source.

•

Power Supply:

– Voltage: 3 V (±1.5 V) to 5 V (±2.5 V)

The input and output are optimized for best perform-

ance with their common-mode voltages
