The DG2031 is a sub 1- (0.75 @ 2.7 V ) dual SPDT analog switch designed for low voltage applications.
The DG2031 has on-resistance matching (less than 0.05 @2.7 V) and flatness (less than 0.2 @ 2.7 V) that are guaranteed over the entire voltage range. Additionally, low logic thresholds makes the DG2031 an ideal interface to low voltage DSP control signals.
