The DG2018 and DG2019 are low voltage, single supply analog switches. The DG2018 is a dual double-pole/doublethrow (DPDT) with two control inputs that each controls a pair of single-pole/double-throw (SPDT). The DG2019 uses one control pin to operate four independent SPDT switches. When operated on a + 3 V supply, the DG2018’s control pins are compatible wit.
• Low voltage operation (1.8 V to 5.5 V)
• Low on resistance
- RDS(on): 6 Ω at 2.7 V
• Low voltage logic compatible
- DG2019: VINH = 1 V
• High bandwidth: 180 MHz
• QFN-16 package
BENEFITS
