0.3 pC Charge Injection, 100 pA Leakage
CMOS ± 5 V / 5 V / 3 V Dual SPDT Analog Switch
DESCRIPTION
The DG636E is a dual SPDT CMOS, analog switch,
designed to operate from a +3 V to +16 V single supply, or
from ± 3 V to ± 8 V, dual supplies. The DG636E is fully
specified at +3 V, +5 V, and ± 5 V.
The DG636E offers ultralow charge injection less than
± 0.4 pC over the entire signal range and leakage currents of
13 pA typical at 25 °C. It offers on resistance of 63
typ.,
and low parasitic capacitance of 3.7 pF source off, and
8.4 pF Drain on. The part is ideal for analog front end, data
acquisition and sample and hold designs providing fast and
precision signal switching.
The DG636E switches one of two inputs to a common
output as determined by the 3-bit binary address lines: A0,
A1, and EN. Each switch conducts equally well in both
directions when on, blocks input voltages up to the supply
level when off, and exhibits break before make switching
action.
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 DG636E operating temperature range is specified from
-40 °C to +125 °C. It is available in 14 lead TSSOP and the
space saving 1.8 mm x 2.6 mm miniQFN package.
FEATURES
• Ultra low charge injection
(Less than ± 0.3 pC, typ. over the full analog
signal range)
• Leakage current < 0.5 nA max. at 85 °C
(for DG636EEQ-T1-GE4)
• Low switch capacitance (C
S(off)
, 3.7 pF typ.)
• Fully specified with single supply operation at 3 V, 5 V, and
dual supplies at ± 5 V
• CMOS / TTL compatible
• 700 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)
• Material categorization: for definitions of compliance

terminal is exposed copper (not plated) as a result of the singulation process in manufacturing. A solder fillet at the exposed copper lip
cannot be guaranteed and is not required to ensure adequate bottom side solder interconnection
