APPLICATIONS
D ADG409 S1A S4B DA DB S4A S1B 1-OF-4 DECODER 1-OF-8 DECODER A0 A1 ENA0 A1 A2 EN 00027-001 Figure 1. GENERAL DESCRIPTION The ADG408/ADG409 are monolithic CMOS analog multiplexers comprising eight single channels and four differential channels, respectively. The ADG408 switches one of eight inputs to a common output as determined by the 3-bit binary address lines A0, A1, and A2. The ADG409 switches one of four differential inputs to a common differential output, as determined by the 2-bit binary address lines A0 and A1. An EN input on both devices is used to enable or disable the device. When the device is disabled, all channels are switched off. The ADG408/ADG409 are designed on an enhanced LC2MOS process that provides low power dissipation yet gives high switching speed and low on resistance. Each channel 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 channels exhibit break- before-make switching action, preventing momentary shorting when switching channels. Inherent in the design is low charge injection for minimum transients when switching the digital inputs. The ADG408/ADG409 are improved replacements for the DG408/DG409 analog multiplexers. PRODUCT HIGHLIGHTS 1. Extended Signal Range. The ADG408/ADG409 are fabricated on an enhanced LC2MOS process, giving an increased signal range that extends to the supply rails. 2. Low Power Dissipation. 3. Low RON. 4. Single-Supply Operation. For applications where the analog signal is unipolar, the ADG408/ADG409 can be operated from a single rail power supply. The parts are fully specified with a single 12 V power supply and remain functional with single supplies as low as 5 V .
