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

(for DG636EQ-T1-E3)

•

•

•

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)
