GENERAL DESCRIPTION
PRODUCT HIGHLIGHTS
1. <0.7 Ω over the full temperature range of –40°C to +85°C.
2. Single 1.65 V to 3.6 V operation.
3. 1.8 V logic compatible.
The ADG824 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
0.7 Ω over the full temperature range. The ADG824 is fully
specified for 3.3 V, 2.5 V, and 1.8 V supply operation.
4. High current carrying capability (300 mA continuous
current at 3.3 V).
Each switch conducts equally well in both directions when on,
and has an input signal range that extends to the supplies. The
ADG824 exhibits break-before-make switching action.
5. Low THD + N (0.06% typical).
6. 1.3 mm × 1.6 mm mini LFCSP package.
The low on resistance of the ADG824 makes this device ideal
for audio switching. In addition, a data rate of 180 Mbps makes
the device suitable for USB low speed (1.5 Mbps) and full speed
(12 Mbps) data switching.
The ADG824 is available in a 1.3 mm × 1.6 mm, 10-lead mini
LFCSP package.
