THAT6261 - THAT

THAT6261 2-Channel Low-Noise ProgrammableGain Preamplifier

The THAT 626x is a family of two-channel “all-inone” digitally controlled preamplifiers with integrated ADC drivers. Gain is programmable from -8 to +34dB. The 626x family includes three products distinguished primarily by step size: Part Step size 6261 1dB 6263 3dB 6266 6dB All three parts offer excellent noise performance: at +34dB gain, the 6261 E.
