GENERAL DESCRIPTION
The ADG1604 is a complementary metal-oxide semiconductor
(CMOS) analog multiplexer and switches one of four inputs to
a common output, D, as determined by the 3-bit binary address
lines, A0, A1, and EN. Logic 0 on the EN pin disables the device.
Each switch conducts equally well in both directions when on
and has an input signal range that extends to the supplies. In
the off condition, signal levels up to the supplies are blocked.
All switches exhibit break-before-make switching action.
Inherent in the design is low charge injection for minimum
transients when switching the digital inputs.
The ultralow on resistance of these switches make them ideal
solutions for data acquisition and gain switching applications where
low on resistance and distortion is critical. The on resistance profile
is very flat over the full analog input range, ensuring excellent
linearity and low distortion when switching audio signals.
The CMOS construction ensures ultralow power dissipation,
making the parts ideally suited for portable and battery-
powered instruments.
PRODUCT HIGHLIGHTS
1. 1.6 Ω maximum on resistance over temperature.
2. Minimum distortion: THD + N = 0.007%.
3. 3 V logic-compatible digital inputs: VINH = 2.0 V, VINL = 0.8 V.
4. No VL logic power supply required.
5. Ultralow power dissipation: <16 nW.
6. 14-lead TSSOP and 16-lead, 4 mm × 4 mm LFCSP.
