GENERAL DESCRIPTION The ADG884 is a low voltage CMOS device containing two
independently selectable single-pole, double-throw (SPDT)
switches. This device offers ultralow on resistance of less than
0.4 Ω over the full temperature range, making the part an ideal
solution for applications that require minimal distortion
through the switch. The ADG884 also has the capability of
carrying large amounts of current, typically 600 mA at 5 V
operation.
The ADG884 is available in a 10 bump, 2.0 mm × 1.50 mm
WLCSP package, a 10-lead LFCSP package, and a 10-lead
MSOP package. These tiny packages make the ADG884 the
ideal solution for space-constrained applications.
When on, each switch conducts equally well in both directions
and has an input signal range that extends to the supplies. The
ADG884 exhibits break-before-make switching action.
PRODUCT HIGHLIGHTS 1. Single 1.8 V to 5.5 V operation.
2. High current handling capability (400 mA continuous
current at 3.3 V).
3. 1.8 V logic-compatible.
4. Low THD + N (0.01% typ).
5. Tiny 2 mm × 1.5 mm WLCSP package, 3 mm × 3 mm
10-lead LFCSP package, and 10-lead MSOP package.

Table 4. 1 Temperature range of the B version is −40°C to +85°C. Guaranteed by design, not subject to production test.
ABSOLUTE MAXIMUM RATINGS TA = 25°C, unless otherwise noted.
Table 5. 1 Overvoltages at IN, S, or D are clamped by internal diodes. Current should be
limited to the maximum ratings given.
Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
Only one absolute maximum rating may be applied at any one
time.
ESD CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the
human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.
