The ADG2108 is a CMOS 8×10 unbuffered analog switch array with dual/single supplies. It features an I2C-compatible interface and a high-speed I2C option. The switch array supports simultaneous update of multiple switches. This product is suitable for applications such as AV switching, automotive infotainment, AV receivers, CCTV, ultrasound applications, KVM switching, telecom applications, test equipment/instrumentation, and PBX systems.
The ADG2108 is an 8 × 10 analog cross‑point switch offering 80 bidirectional channels. It supports dual‑single supply operation (Vop = +5 V to +12 V, Vss = –5 V to 0 V) and features double‑buffered inputs, simultaneous update of multiple switches, and a reset option that turns all channels off on power‑up. The device is supplied in a 32‑lead LFCSP_VQ package (5 mm × 5 mm).
Typical applications include automotive infotainment, KVM switching, telecom, test equipment, and ultrasound systems. The datasheet provides detailed specifications, timing diagrams, pin configurations, and ordering information for both B‑version (‑40 °C to +85 °C) and Y‑version (‑40 °C to +125 °C) parts.
