DG636
Vishay Siliconix
0.5 pC Charge Injection, 100 pA Leakage,
Dual SPDT Analog Switch
DESCRIPTION
The DG636 is an analog CMOS, dual SPDT switch,
designed to operate from a + 2.7 V to + 12 V single supply or
from ± 2.7 V to ± 5.0 V, dual supplies. The DG636 is fully
specified at + 3 V, + 5 V and ± 5 V. All control logic inputs have
guaranteed 2 V logic high limits when operating from + 5 V or
± 5 V supplies and 1.4 V when operating from a 3 V supply.
The DG636 switches conduct equally well in both directions
and offer rail to rail analog signal handling. < 1 pC low charge
injection, coupled with very low switch capacitance and
leakage current makes this product ideal for use in precision
instrumentation applications. Operating temperature range
is specified from - 40 °C to + 125 °C. The DG636 is available
in 14 lead TSSOP and the space saving 1.8 mm x 2.6 mm
miniQFN package.
FEATURES
• Ultra low charge injection (± 0.5 pC, typ. over
the full analog signal range)
• Leakage current < 0.5 nA max. at 85 °C _RoHS
(for DG636EQ-T1-E3)
COMPLIANT
• Low switch capacitance (C_soff, 2 pF typ.)
• Low R_DS(on) - 115  max.
• Fully specified with single supply operation at 3.0 V, 5.0
V and dual supplies at ± 5.0 V
• Low voltage, 2.5 V CMOS/TTL compatible
• 600 MHz, - 3 dB bandwidth
• Excellent isolation and crosstalk performance (typ. > - 60
dB at 10 MHz)
• Fully specified from - 40 °C to 85 °C and - 40 °C to
+ 125 °C
• 14 pin TSSOP and 16 pin miniQFN package (1.8 mm x
2.6 mm)
• Compliant to RoHS directive 2002/95/EC
APPLICATIONS
• High-end data acquisition
• Medical instruments
• Precision instruments
• High speed communications applications
• Automated test equipment
• Sample and hold applications
