ADG2108BCPZ-REEL7

Overview

The ADG2108BCPZ-REEL7 is an I2C-compatible CMOS analog crosspoint switch featuring an 8 × 10 unbuffered array, totaling 80 bidirectional channels. It supports standard, fast (400 kHz), and high-speed (3.4 MHz) I2C interfaces with double-buffered input logic for simultaneous updates via the LDSW command. The device operates on dual ±5 V or single +12 V supplies, offering a maximum on-resistance of 35 Ω, low quiescent current under 20 µA, and up to 300 MHz bandwidth. Packaged in a 32-lead LFCSP_WQ (5 mm × 5 mm), it includes power-on reset functionality and readback capabilities.
