THS4561 Datasheet Fully Differential Amplifier

Manufacturer: Texas Instruments

General Description

The THS4561 fully differential amplifier (FDA) offers a simple interface from single-ended sources to the VS+ + +5 V ± VS± + ±5 V ± THS4561 Using ±5 VS 3.57 k 330 pF 357 PCM Audio DAC Output 357 909 10 nF 150 pF 10 nF 909 20 VS+ PD FDA VS± 330 pF 20 G = 10 V/V 50-kHz MFB Butterworth Output Driver 3.57 k Gain of 10 V/V PCM Audio DAC Output With Second-Order MFB Filter at 50 kHz differential output required by precision analog-todigital converters (ADCs).

Designed for a very low, 8-Hz, 1/f voltage noise corner and low, 130-dB total harmonic distortion (THD) while consuming only a 775-µA quiescent current, the THS4561 is well suited for power-sensitive data acquisition (DAQ) systems where high performance is required with the best signal-to-noise ratio (SNR) and spurious-free dynamic range (SFDR) through the amplifier and ADC combination.
