ADG2188 is an 8x8 unbuffered analog switch array with dual/single supplies and I2C-compatible interface. It supports 3.4MHz high speed I2C option, 32-lead LFCSP_VQ (5mm x 5mm) package, double-buffered input logic, simultaneous update of multiple switches, bandwidth up to 300MHz, fully specified at dual ±5V/single +12V operation, on resistance 35Ω maximum, low quiescent current < 20μA. ADG2188 is widely used in TV AV switching, automotive infotainment, AV receivers, CCTV, ultrasound applications, KVM switching, telecom applications, test equipment/instrumentation, PBX systems.
The ADG2188 analog cross‑point switch provides an 8 × 8 matrix of bidirectional channels that can be configured as inputs or outputs. It supports standard, full‑speed and high‑speed (3.4 MHz) I²C interfaces, allowing simultaneous updates of multiple switches and a reset/off condition at power‑on.
Typical applications include automotive infotainment, KVM switching, telecom, test equipment, and ultrasound systems. The device is offered in a 32‑lead LFCSP_VQ package and is available in versions covering –40 °C to +85 °C (B) and –40 °C to +125 °C (Y).
