THAT offers various combinations of our Mic Preamps and Controllers as specially prices sets, as well as a series of all-in-One digitally controlled preamplifiers with integrated ADC drivers.
626x Dual Programmable-Gain Preamplifier and ADC Driver IC
The THAT 626x is a family of two-channel “all-in-one” digitally controlled preamplifiers with integrated ADC drivers. Gain is programmable from -8 to +34 dB. These low-power (60 mW) devices can be powered from unipolar (+10 V and +5 V) or bipolar (±5 V) supplies. The 626x family includes three products distinguished primarily by step size.
